-------------------------------------------------------------------------------- /notes/Dart_Intro.md: -------------------------------------------------------------------------------- 1 | ## Dart入门笔记 2 | > 参考文献: https://www.dartlang.org/samples 3 | 4 | 感觉最近要入坑 **Flutter** 了, 于是决定先了解一下它用的语言: **Dart** 的使用方法，然后写一篇笔记总结一下常用方法。 5 | 6 | #### 运行代码的环境 7 | 8 | 大多数代码都可以在这个 DartPad 上运行: 9 | [https://dartpad.dartlang.org/](https://dartpad.dartlang.org/) 10 | #### 首先就是一个 Hello Word 11 | 12 | ``` 13 | void main() { 14 | print('Hello, World!'); 15 | } 16 | ``` 17 | #### Dart 变量类型 18 | 19 | Dart 可以像 JS 一样用 var 来申明不指定它类型的变量，也可以申明特定类型的变量。 20 | 21 | 用 var 来申明变量： 22 | 23 | ``` 24 | // 字符串 25 | var name = 'Voyager I'; 26 | // 整型 27 | var year = 1977; 28 | // 浮点型 29 | var antennaDiameter = 3.7; 30 | // 列表 List 31 | var flybyObjects = ['Jupiter', 'Saturn', 'Uranus', 'Neptune']; 32 | // Map 类型 33 | var image = { 34 | 'tags': ['saturn'], 35 | 'url': '//path/to/saturn.jpg' 36 | }; 37 | ``` 38 | 39 | 申明特定类型的变量： 40 | 41 | ``` 42 | // 字符串 43 | String name = 'Voyager I'; 44 | // 整型 45 | int year = 1977; 46 | // 浮点型 47 | double antennaDiameter = 3.7; 48 | // 列表 List 49 | List flybyObjects = ['Jupiter', 'Saturn', 'Uranus', 'Neptune']; 50 | // Map 类型 51 | Map image = { 52 | 'tags': ['saturn'], 53 | 'url': '//path/to/saturn.jpg' 54 | }; 55 | ``` 56 | 然后，赋值变量的时候要记得考虑关键字：[关键字表](http://wiki.jikexueyuan.com/project/dart-language-tour/keywords.html) 57 | 58 | 59 | #### 条件语句 60 | 61 | ``` 62 | //if 语句 63 | if (判断条件) { 64 | 执行语句; 65 | } else if (判断条件) { 66 | 执行语句; 67 | } else{ 68 | 执行语句; 69 | } 70 | ``` 71 | 72 | ``` 73 | // switch case 74 | var number = '1'; 75 | switch (number) { 76 | case '1': 77 | print('The number is 1'); 78 | break; 79 | case '2': 80 | print('The number is 2'); 81 | break; 82 | case '3': 83 | print('The number is 3'); 84 | break; 85 | default: 86 | print('The number is Unknown'); 87 | } 88 | ``` 89 | 90 | #### 循环语句 91 | 两种 For 循环 92 | 93 | ``` 94 | // 第一种，就像 java 的 for 循环 95 | for (var i = 0; i < 2; i++) { 96 | print(i); 97 | } 98 | // 第二种，遍历 List 和 Set, 和 Python 用法很像 99 | var myList = [0, 1, 2]; 100 | for (var x in myList) { 101 | print(x); // 0 1 2 102 | } 103 | ``` 104 | While 循环 105 | 106 | ``` 107 | var i=1; 108 | while (i < 200) { 109 | print(i); 110 | i += 1; 111 | } 112 | ``` 113 | 和其他语言一样，dart 也可以使用 break 和 continue 114 | 115 | #### Dart 函数 116 | ``` 117 | //计算一个斐波那契数列 118 | int fibonacci(int n) { 119 | if (n == 0 || n == 1) return n; 120 | return fibonacci(n - 1) + fibonacci(n - 2); 121 | } 122 | 123 | var result = fibonacci(20); 124 | ``` 125 | 上面这个函数看着和一般的语言没差别，但是在 Dart 中和还有一个神奇的写法: 126 | 127 | ``` 128 | void main() => RunWhile(20); 129 | 130 | RunWhile(n) { 131 | var i=1; 132 | while (i < n) { 133 | print(i); 134 | i += 1; 135 | } 136 | } 137 | ``` 138 | 这么 main() 函数后面直接跟了一个 => 来调用 RunWhile 方法，这是Dart中单行函数或方法的简写。 139 | 140 | #### 引用库 141 | 142 | 143 | ``` 144 | // 导入内置库 145 | import 'dart:math'; 146 | 147 | // 导入外部库 148 | import 'package:test/test.dart'; 149 | 150 | // 通过文件系统路径导入库 151 | import 'path/to/my_other_file.dart'; 152 | ``` 153 | 154 | #### 创建类 155 | 156 | ``` 157 | // 创建一个猫的类 158 | class Cat { 159 | String name; 160 | num age; 161 | Cat(name, age) { 162 | //初始化 163 | this.name=name; 164 | this.age=age; 165 | } 166 | void talk() { 167 | print('My name is $name, I am ${age} years old now.'); 168 | } 169 | } 170 | 171 | void main(){ 172 | // 实例化并调用方法 173 | var myCat=new Cat("小爪", 1); // 没错，我的🐱叫小爪！！ 174 | myCat.talk(); 175 | } 176 | ``` 177 | 178 | 结尾了结尾了！umm, 推荐一个网站，我是看这个网站总结的: 179 | [https://www.dartlang.org/guides/language](https://www.dartlang.org/guides/language) 180 | 181 | 最后！希望 Dart 和 Flutter 能发展的好起来！ 182 | 183 | umm, 就这样，拜拜👋 184 | 185 | 186 | 187 | -------------------------------------------------------------------------------- /notes/Flutter_Async.md: -------------------------------------------------------------------------------- 1 | ## Flutter 学习之路 - 异步任务 2 | > 实验 Flutter 的异步任务 --- [代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day10.dart) 3 | 4 | ### Fultter 异步任务试验 5 | 6 | Flutter 在很多地方需要用到异步的任务，例如，加载网络数据，任务延迟执行等，所以异步任务是不可避免的问题。本次试验主要试验了下面几种情况： 7 | 8 | - 用 Future, then 实现任务延迟执行 9 | - 用 async 和 await 实现任务延迟执行 10 | - 测试调用 async 方法时，代码的执行顺序问题 11 | 12 | [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day10.dart) 13 | 14 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_async.gif) 15 | 16 | 17 | #### 用 Future, then 实现任务延迟执行 18 | 19 | Future 可以用来执行未来要执行的方法，例如下面代码，先输出 ”Started“, 调用 Future 以后过了一秒钟，再输出 ”Completed Task1“。 20 | 21 | ``` 22 | void thenCatch(){ 23 | mytext="Started"; 24 | setMyTextState(mytext); 25 | // then 用来说明 1 second 后做什么 26 | Future.delayed(Duration(seconds: 1)).then((_){ 27 | // 当运行完成 28 | mytext = mytext + "\n" + "Completed Task1"; 29 | setMyTextState(mytext); 30 | }).catchError((e){ 31 | // 当运行失败 32 | mytext=mytext+"\n"+'failed: ${e.toString()}'; 33 | setMyTextState(mytext); 34 | }); 35 | } 36 | ``` 37 | 38 | #### 用 async 和 await 实现任务延迟执行 39 | 40 | await 也是 Flutter 中很好的一种执行异步任务的方法。 41 | 42 | 但是要使用await，必须在有async标记的函数中运行，否则这个await会报错。 43 | 44 | 下面是一个加了 await 的方法，它的输出是怎么样呢? 45 | 46 | ``` 47 | Future asyncAwait() async{ 48 | mytext="Started"; 49 | setMyTextState(mytext); 50 | try{ 51 | // 这里没有 .then, 要加 await, await 是说在 await 完成前别往下执行 52 | await Future.delayed(Duration(seconds: 1)); 53 | mytext=mytext+"\n"+"Completed Task1"; 54 | setMyTextState(mytext); 55 | await Future.delayed(Duration(seconds: 1)); 56 | mytext=mytext+"\n"+"Completed Task2"; 57 | setMyTextState(mytext); 58 | }catch(e){ 59 | print('failed: ${e.toString()}'); 60 | } 61 | } 62 | ``` 63 | 64 | 答案是： 65 | 66 | ``` 67 | Started 68 | --- 1 second --- 69 | Completed Task1 70 | --- 2 second --- 71 | Completed Task2 72 | ``` 73 | 先输出 ”Start“, 然后过一秒，输出 ”Completed Task1“ 再过一秒输出 ”Completed Task2“ 。 74 | 75 | 如果把方法里的 await 去掉，看看会发生什么呢，结果是，Task1 和 Task2不会等待Future.delayed 完成，会直接执行。 76 | 77 | ``` 78 | Started 79 | Completed Task1 80 | Completed Task2 81 | --- 1 second --- 82 | ``` 83 | 84 | #### 测试调用 async 方法时，代码的执行顺序问题 85 | 86 | 那如果说，代码依次是 Task1, Task2, Task3, Task4, Task2 是一个异步的方法，Task3 , Task4 需要等待 Task2 完成吗？ 87 | 88 | 代码如下： 89 | 90 | ``` 91 | Future asyncAwaitWithTask() async{ 92 | mytext="Started"; 93 | setMyTextState(mytext); 94 | try{ 95 | // 这里没有 .then, 要加 await, await 是说在 await 完成前别往下执行 96 | await Future.delayed(Duration(seconds: 1)); 97 | mytext=mytext+"\n"+"Completed Task1"; 98 | setMyTextState(mytext); 99 | task2(); 100 | mytext=mytext+"\n"+"Completed Task3"; 101 | setMyTextState(mytext); 102 | mytext=mytext+"\n"+"Completed Task4"; 103 | setMyTextState(mytext); 104 | }catch(e){ 105 | print('failed: ${e.toString()}'); 106 | } 107 | } 108 | 109 | void task2() async{ 110 | await Future.delayed(Duration(seconds: 1)); 111 | mytext=mytext+"\n"+"Completed Task2"; 112 | setMyTextState(mytext); 113 | } 114 | ``` 115 | 答案是, Task3, Task4 会先于 Task2 执行，最前面的 GIF 图就是在运行的这个场景。 116 | 117 | ``` 118 | Started 119 | --- 1 second --- 120 | Completed Task1 121 | Completed Task3 122 | Completed Task4 123 | --- 2 second --- 124 | Completed Task2 125 | ``` 126 | 127 | 128 | ### Flutter 学习之路 Github 地址 129 | 130 | [https://github.com/draftbk/flutter_road](https://github.com/draftbk/flutter_road) 131 | 132 | 133 | 134 | 135 | 136

（[代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day2.dart)） 3 | 4 | ### Button 实验 5 | 6 | 实验了 Button 常用的一些功能 7 | 8 | - RaisedButton 9 | - FlatButton 10 | - 悬浮按钮 （FloatingActionButton） 11 | - 宽的悬浮按钮 （FloatingActionButton.extended） 12 | - 滚动条（Slider） 13 | - 复选框（Checkbox） 14 | - 选项按钮 （Radio Buttons） 15 | 16 | [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day2.dart) 17 | 18 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_button.gif) 19 | 20 | 21 | 22 | #### RaisedButton 23 | 24 | 用 child 的方式添加文字，用 onPressed 方法监听按钮行为。 25 | 26 | ``` 27 | // RaisedButton 28 | Padding( 29 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 30 | child: new RaisedButton( 31 | onPressed: () {print('button click');}, 32 | child: new Text("RaisedButton"), 33 | ), 34 | ), 35 | ``` 36 | 37 | #### FlatButton 38 | 39 | 和 RaisedButton 一样用 child 的方式添加文字，用 onPressed 方法监听按钮行为。 40 | FlatButton 本身是透明且没有突出的，所以设置了 color 使它更明显 41 | 42 | 43 | ``` 44 | // FlatButton 45 | Padding( 46 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 47 | child: new FlatButton( 48 | onPressed: () {print('button click');}, 49 | child: new Text("FlatButton"), 50 | color: Color(0xFFe16552), 51 | ), 52 | ), 53 | ``` 54 | 55 | #### 悬浮按钮 （FloatingActionButton） 56 | 57 | 悬浮按钮，可以通过改变 child 来设置 button 上显示文字或者 icon。 58 | 59 | 同时这里有个要注意的点，就是 **material design** 建议每个屏幕只有一个 FloatingActionButton，所以如果一定要两个（比如像我这样写demo），就要把这个 heroTag 设置为 null。 60 | 61 | ``` 62 | //FloatingActionButton 多个FloatingActionButton的时候会报错，要加 heroTag: null 63 | Padding( 64 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 65 | child: Row( 66 | mainAxisAlignment: MainAxisAlignment.spaceEvenly, 67 | children: [ 68 | // FloatingActionButton 69 | new FloatingActionButton( 70 | onPressed: () {print('button click');}, 71 | foregroundColor: Colors.white, 72 | backgroundColor: Color(0xFFf19670), 73 | child: new Icon(Icons.add), 74 | heroTag: null, 75 | ), 76 | // FloatingActionButton 77 | new FloatingActionButton( 78 | onPressed: () {print('button click');}, 79 | foregroundColor: Colors.white, 80 | backgroundColor: Color(0xFFf19670), 81 | child: new Text("文字"), 82 | heroTag: null, 83 | ), 84 | ], 85 | ), 86 | ), 87 | ``` 88 | #### 宽的悬浮按钮 （FloatingActionButton.extended） 89 | 90 | 可以看我上面的动图，有这个按钮的效果，感觉还挺棒的哈哈。 91 | 92 | ``` 93 | // FloatingActionButton.extended 94 | Padding( 95 | padding: const EdgeInsets.fromLTRB(0.0, 15.0, 0.0, 0.0), 96 | child: new FloatingActionButton.extended( 97 | onPressed: () { 98 | print('button click'); 99 | }, 100 | foregroundColor: Colors.white, 101 | backgroundColor: Colors.amber, 102 | icon: new Icon(Icons.flag,color: Colors.red,), 103 | label: new Text('FloatingActionButton.extended', maxLines: 1), 104 | ) 105 | ), 106 | ``` 107 | 108 | #### 滚动条（Slider） 109 | 110 | ``` 111 | Padding( 112 | padding: const EdgeInsets.fromLTRB(0.0, 15.0, 0.0, 0.0), 113 | child: new Slider( 114 | value: mCurrentValue, 115 | min: 1.0, 116 | max: 10.0, 117 | onChanged: (e) { 118 | setState(() { 119 | //四舍五入的双精度值 120 | mCurrentValue = e.roundToDouble(); 121 | }); 122 | } 123 | ) 124 | ), 125 | ``` 126 | 127 | #### 复选框（Checkbox） 128 | 129 | ``` 130 | Padding( 131 | padding: const EdgeInsets.fromLTRB(0.0, 15.0, 0.0, 0.0), 132 | child: new Checkbox( 133 | value: isChecked, 134 | onChanged: (bool){ 135 | setState(() { 136 | isChecked=bool; 137 | }); 138 | }, activeColor: Colors.blue, 139 | ) 140 | ), 141 | ``` 142 | 143 | #### 选项按钮 （Radio Buttons） 144 | 145 | 这里如果把新建的 Radio 的值设置为 null, 这个 Radio 就是不可选的，会显示一个灰色的状态。 146 | 147 | ``` 148 | // Radio 149 | Padding( 150 | padding: const EdgeInsets.fromLTRB(0.0, 15.0, 0.0, 0.0), 151 | child: new ButtonBar(//ButtonBar：水平排列按钮 152 | alignment: MainAxisAlignment.center, 153 | children: [ 154 | //value和groupValue值一样的话,则按钮选中 155 | new Radio(value: 1, 156 | groupValue: groupValue1, 157 | onChanged: (int e) => updateGroupValue(e)), 158 | new Radio(value: 2, 159 | groupValue: groupValue1, 160 | onChanged: (int e) => updateGroupValue(e)), 161 | new Radio(value: 3, 162 | groupValue: groupValue1, 163 | onChanged: (int e) => updateGroupValue(e)), 164 | new Radio(value: 4, 165 | groupValue: groupValue1, 166 | onChanged: (int e) => updateGroupValue(e)), 167 | //value 值为 null 则表示按钮不可用 168 | new Radio(value: null, groupValue: null, onChanged: null) 169 | ], 170 | ) 171 | ), 172 | ``` 173 | 174 | #### 遇到的问题 175 | 176 | 感觉对于控件，各个参数主要是看官网文档，然后自己改改, 所以还是记录一下遇到的问题。 177 | 178 | ##### 问题一: 当多个 FloatingActionButton 的时候程序运行会黑屏 179 | 180 | 解决方案：把 **heroTag** 设置为 **null** 181 | 182 | ``` 183 | new FloatingActionButton( 184 | onPressed: () {print('button click');}, 185 | foregroundColor: Colors.white, 186 | backgroundColor: Color(0xFFf19670), 187 | child: new Icon(Icons.add), 188 | heroTag: null, 189 | ), 190 | ``` 191 | 看了官网的说明，大意是 **material design** 建议每个屏幕只有一个 FloatingActionButton，所以如果一定要两个（比如像我这样写demo），就把这个 heroTag 设置为 null。 192 | 193 | 官网对于 heroTag 的说明: [link](https://docs.flutter.io/flutter/material/FloatingActionButton/heroTag.html) 194 | 195 | #### Flutter 学习之路 Github 地址 196 | 197 |

Flutter 学习之路 - 对话框（Dialog） 2 | > 实验一些常用的对话框实现方式--- [代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day6.dart) 3 | 4 | ### Dialog 实验 5 | 6 | 补上这个应该在第六篇博客就想写的坑，试验在 Flutter 中对 dialog 的各种使用方式。 7 | 8 | Flutter 官方建议使用 SimpleDialog 和 AlertDialog 两种方式来实现 Dialog, 然后这篇文章受下面这篇安卓的博客的启发，尝试实现一些不同功能的 Dialog: 9 | 10 | [https://www.cnblogs.com/gzdaijie/p/5222191.html](https://www.cnblogs.com/gzdaijie/p/5222191.html) 11 | 12 | 13 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_navigationbar.gif) 14 | 15 | 16 | #### 底部提示栏 17 | 18 | 最简单的提示方式，从底部弹出提示。 19 | 20 | ```Dart 21 | Future _showSnackBar(BuildContext context, String text) async { 22 | final scaffold = Scaffold.of(context); 23 | scaffold.showSnackBar( 24 | SnackBar( 25 | content: Text(text), 26 | ), 27 | ); 28 | } 29 | ``` 30 | 31 | 32 | #### 简单的 Dialog 33 | 34 | 见到提示对话框，只是提示功能，不需要交互。当看到显示之后，就只需要点击 “是的”，表示知道就行了。 35 | 36 | ```Dart 37 | Future _showSnackBar(BuildContext context, String text) async { 38 | final scaffold = Scaffold.of(context); 39 | scaffold.showSnackBar( 40 | SnackBar( 41 | content: Text(text), 42 | ), 43 | ); 44 | } 45 | ``` 46 | 47 | #### 一个列表的 Dialog 48 | 49 | 列表的 Dialog 可以选择点击不同的 item 进行不同的操作。 50 | 51 | 在实现的时候遇到了一个坑，就是，在SingleChildScrollView里不能用 ListView，是直接在 ListBody 里面加入 ListTile 就好了。 52 | 53 | ```Dart 54 | Future _showListAlertDialog() async { 55 | return showDialog( 56 |

Flutter 学习之路 - Gridview 2 | > 实验一些常用的 Gridview 功能 --- [代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day5.dart) 3 | 4 | ### Gridview 实验 5 | 6 | Flutter 学习之路第五次实验，实验了 Gridview 常用的一些功能，用 Gridview 实现单词软件的一个基础功能。 7 | 8 | - 设置 gridview 各个属性设置（间距，每行个数，长宽比） 9 | - 自定义 item, 以及 gridview item 点击事件 10 | - 动态添加 gridview 的 item 11 | 12 | [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day5.dart) 13 | 14 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_gridview.gif) 15 | 16 | 17 | #### 设置 gridview 各个属性设置（间距，每行个数，长宽比） 18 | 19 | - 用 crossAxisCount 来设置每行个数 20 | - 用 crossAxisSpacing 设置水平间隙 21 | - 用 mainAxisSpacing 设置上下间隙 22 | - 用 childAspectRatio 来设置宽高比例 23 | 24 | ``` 25 | child: GridView.count( 26 | // 每行有几个子控件 27 | crossAxisCount: 2, 28 | // 水平子Widget之间间距 29 | crossAxisSpacing: 10.0, 30 | // 设置上下间隙 31 | mainAxisSpacing: 8.0, 32 | // 子Widget宽高比例 33 | childAspectRatio: 2.0, 34 | children: List.generate(listNumber, (index) { 35 | return gridItem(context, index); 36 | }), 37 | ), 38 | ``` 39 | 40 | #### 自定义 item, 以及 gridview item 点击事件 41 | 42 | 这两个一起写是因为，实际上，item 点击是建立在自定义 item 上的，能自定义 item 了就能点击了。 43 | 44 | 自定义一个 gridItem 的 Widget 45 | 46 | ``` 47 | Widget gridItem (BuildContext context, int _index) { 48 | int index=_index%words.length; 49 | return Container( 50 | alignment: Alignment.center, 51 | child: GestureDetector( 52 | onTap: () { 53 | setState(() { 54 | String temp=words[index]; 55 | words[index]=translations[index]; 56 | translations[index]=temp; 57 | }); 58 | }, 59 | child: Text( 60 | words[index], 61 | style: TextStyle( 62 | fontSize: 28, 63 | color: Colors.white, 64 | ), 65 | ), 66 | ), 67 | color:myColor, 68 | ); 69 | } 70 | ``` 71 | 72 | 用 List.generate 加载自定义的 gridItem 73 | 74 | ``` 75 | Widget gridViewSection = Builder( 76 | builder: (context) => Container( 77 | margin: EdgeInsets.fromLTRB(5.0, 5.0, 5.0, 5.0), 78 | height: 600.0, 79 | child: GridView.count( 80 | // 每行有几个子控件 81 | crossAxisCount: 2, 82 | // 水平子Widget之间间距 83 | crossAxisSpacing: 10.0, 84 | // 水平子Widget之间间距 85 | mainAxisSpacing: 8.0, 86 | // 子Widget宽高比例 87 | childAspectRatio: 2.0, 88 | children: List.generate(listNumber, (index) { 89 | return gridItem(context, index); 90 | }), 91 | ), 92 | ) 93 | ); 94 | ``` 95 | 96 | #### 动态添加 gridview 的 item 97 | 98 | 这个和之前写 listview 的动态添加套路差不多，就是改变下面这个 listNumber 的值，就可以完成动态添加. 99 | 100 | ``` 101 | children: List.generate(listNumber, (index) { 102 | return gridItem(context, index); 103 | }), 104 | ``` 105 | 同样，别忘了用 setState 106 | 107 | ``` 108 | onTap: () { 109 | setState(() { 110 | String temp=words[index]; 111 | words[index]=translations[index]; 112 | translations[index]=temp; 113 | }); 114 | }, 115 | ``` 116 | 117 | ### Flutter 学习之路 Github 地址 118 | 119 |

学习之路第三次试验，试验了有关于 Image 常用的一些功能，包括图片本地加载，图片和 GIF 的网络加载，图片渐现呈现，从网络加载图片并缓存在内存中。 7 | 8 | [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day3.dart) 9 | 10 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_image.gif) 11 | 12 | ##### 加载本地图片 13 | 14 | 在 lib 同级目录下创建文件夹 images, 并且在 pubspec.yaml 文件中添加如下几行。 15 | 16 | ``` 17 | flutter: 18 | assets: 19 | - images/flutter.png 20 | ``` 21 | 22 | 用 AssetImage 获取图片 23 | 24 | ``` 25 | // Image from asserts 26 | Padding( 27 | padding: const EdgeInsets.fromLTRB(0.0, 20.0, 0.0, 0.0), 28 | child: new Image( 29 | image:new AssetImage('images/flutter.png'), 30 | width: 50, 31 | height: 50, 32 | ), 33 | ), 34 | ``` 35 | 36 | ##### 根据网络链接加载图片 37 | 38 | ``` 39 | // Image from internet 40 | Padding( 41 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 42 | child: Image.network( 43 | 'https://github.com/draftbk/Blog_Resource/blob/master/Flutter/picture/day3/flutter.png?raw=true', 44 | scale: 4, 45 | ), 46 | ), 47 | ``` 48 | 49 | ##### 从网络链接加载 **GIF** 50 | 51 | 可以很方便地加载 GIF 是个很棒的功能了，找了个 Google 动图哈哈 52 | 53 | ``` 54 | // Gif from internet 55 | Padding( 56 | padding: const EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0), 57 | child:Image.network( 58 | 'https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/day3/google.gif?raw=true', 59 | scale: 4, 60 | ), 61 | ), 62 | ``` 63 | 64 | ##### FadeInImage（图片渐现呈现） 65 | 66 | 在 pubspec.yaml 加入 cached\_network\_image 67 | 68 | ``` 69 | // FadeInImage 70 | Padding( 71 | padding: const EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0), 72 | child: FadeInImage.memoryNetwork( 73 | width: 180, 74 | height: 180, 75 | placeholder: kTransparentImage, 76 | image: 'https://github.com/draftbk/Blog_Resource/blob/master/Flutter/picture/day3/flutter.png?raw=true', 77 | ), 78 | ), 79 | ``` 80 | 81 | ##### CachedNetworkImage （从网络加载图片并缓存在内存中） 82 | 83 | 在 pubspec.yaml 加入 cached\_network\_image 84 | 85 | ``` 86 | // CachedNetworkImage 87 | Padding( 88 | padding: const EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0), 89 | child: CachedNetworkImage( 90 | width: 100, 91 | height: 100, 92 | placeholder: CircularProgressIndicator(), 93 | imageUrl: 94 | 'https://github.com/draftbk/Blog_Resource/blob/master/Flutter/picture/day3/flutter.png?raw=true', 95 | ), 96 | ), 97 | ``` 98 | 99 | 100 | #### 遇到的问题 101 | 102 | 所以还是记录一些自己遇到的问题。 103 | 104 | ##### 问题一: 当我使用如下代码加载 Gif 以及 png 时，不能显示 105 | 106 | 107 | ``` 108 | // Gif from internet 109 | adding( 110 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 111 | child:Image.network( 112 | 'https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/day3/google.gif?raw=true', 113 | scale: 2, 114 | ), 115 | ) 116 | ``` 117 | 118 | 解决方法：在链接后面加上 **?raw=true** 就可以显示了 119 | 120 | ``` 121 | 'https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/day3/google.gif?raw=true', 122 | ``` 123 | ##### 问题二: 不知道 assets 文件夹在哪创建，图片放哪可以被用到 124 | 125 | 126 | 查了一下发现，其实不用非要 assets 文件夹，Flutter 使用 pubspec.yaml 文件（位于项目根目录），来识别应用程序所需的asset。 可以创建一个其他名字的文件夹来标识 assets 路径。 127 | 128 | ``` 129 | flutter: 130 | assets: 131 | - images/flutter.png 132 | ``` 133 | 134 | ##### 问题三：在导入 package 的时候有时候不知道导入什么版本 135 | 136 | 懒人方法：any 137 | 138 | ``` 139 | dependencies: 140 | flutter: 141 | sdk: flutter 142 | transparent_image: any 143 | cached_network_image: any 144 | ``` 145 | 146 | ##### 问题四：最开始没有给 Container 设置宽度，在加载图片时动画布局变化很糟（果然还是新手233） 147 | 148 | 解决：给 Container 设置 width 149 | 150 | ``` 151 | Widget buttonSection = Container( 152 | padding: const EdgeInsets.all(15.0), 153 | width: 1000, 154 | ``` 155 | 156 | #### Flutter 学习之路 Github 地址 157 | 158 | [https://github.com/draftbk/flutter_road](https://github.com/draftbk/flutter_road) 159 | 160 | 161 | 162 | 163 | 164 | 165 |

Flutter 学习之路 - Listview 入门 2 | > 实验一些常用的 List 功能 --- [代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day4.dart) 3 | 4 | ### Listview 实验 5 | 6 | 实验了 Listview 常用的一些功能 7 | 8 | - 实现水平的 Listview 9 | - 给Listview item 加上点击事件 10 | - Listview 动态更新 11 | 12 | [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day4.dart) 13 | 14 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_listview.gif) 15 | 16 | #### 实现水平的 Listview 17 | 18 | 把属性 scrollDirection 设置为 Axis.horizontal 就能水平了，真的好方便。下面的代码为了避免太长我就选了一部分，实际上children还要多才有效果，可以看我 github 上的源码，或者自己加几个就好了。 19 | 20 | 21 | ``` 22 | child: ListView( 23 | scrollDirection: Axis.horizontal, 24 | children: [ 25 | Container( 26 | width: 160.0, 27 | color: Colors.red, 28 | ), 29 | Container( 30 | width: 160.0, 31 | color: Colors.blue, 32 | ), 33 | // Add more childre 34 | ], 35 | ), 36 | ``` 37 | 38 | #### 给 Listview item 加上点击事件 39 | 40 | 点击事件感觉和处在 listview 里的 children 有关，children 是怎么设置点击事件，就按它的设置就好。 41 | 42 | ``` 43 | child: ListView( 44 | children: [ 45 | ListTile( 46 | leading: Icon(Icons.map), 47 | title: Text('Map'), 48 | onTap: (){ 49 | _showToast(context,"Map"); 50 | }, 51 | ), 52 | ], 53 | ) 54 | ``` 55 | 56 | ##### Listview 动态更新 57 | 用 ListView.builder 以及 一个外部的 List, 然后写一个方法更新 List 的值 58 | 59 | ``` 60 | List items=[]; 61 | // show listview by item 62 | Widget dynamicSection = Container( 63 | margin: EdgeInsets.symmetric(vertical: 5.0), 64 | height: 200.0, 65 | child: ListView.builder( 66 | itemCount: items.length, 67 | itemBuilder: (context,index){ 68 | return ListTile( 69 | leading: Icon(Icons.send), 70 | title: new Text("NewItem $index")); 71 | } 72 | ) 73 | ); 74 | // modify items 75 | void _addListDate(){ 76 | setState(() { 77 | items.add(1); 78 | }); 79 | } 80 | ``` 81 | 82 | 83 | #### 遇到的问题 84 | 85 | 记录一下遇到的问题。 86 | 87 | ##### 问题一: Snackbar 报错不显示 88 | 89 | 原本代码： 90 | 91 | ``` 92 | Widget basicListSection = Container( 93 | margin: EdgeInsets.symmetric(vertical: 20.0), 94 | height: 200.0, 95 | child: ListView( 96 | children: [ 97 | ListTile( 98 | leading: Icon(Icons.map), 99 | title: Text('Map'), 100 | onTap: (){ 101 | _showToast(context,"Map"); 102 | }, 103 | ), 104 | ], 105 | ) 106 | ); 107 | ``` 108 | 109 | 原因：原本用的 context 是 Scaffold 的实例化的 widget 的 context, 不是 Scaffold 的。 110 | 111 | 参考：[link](https://stackoverflow.com/questions/51304568/scaffold-of-called-with-a-context-that-does-not-contain-a-scaffold/51304732) 112 | 113 | 所以要改成下面这样：(用 Builder( 114 | builder: (context) => ) 包起来 115 | 116 | ``` 117 | Widget basicListSection = Builder( 118 | builder: (context) => Container( 119 | margin: EdgeInsets.symmetric(vertical: 20.0), 120 | height: 200.0, 121 | child: ListView( 122 | children: [ 123 | ListTile( 124 | leading: Icon(Icons.map), 125 | title: Text('Map'), 126 | onTap: (){ 127 | _showToast(context,"Map"); 128 | }, 129 | ), 130 | ], 131 | ) 132 | ) 133 |

[代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day7.dart) 3 | 4 | ### NavigationBar 实验 5 | 6 | 7 | - 底部导航栏 [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day7.dart) 8 | - 顶部导航栏 [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/subpage/TopBarPage.dart) 9 | 10 | 11 | 12 | 13 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_navigationbar.gif) 14 | 15 | 16 | #### 底部导航栏（Part1） 17 | 18 | 底部导航用 PageView 和 BottomNavigationBar 完成。大段的代码就不贴了，在 [Github 代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day7.dart) 就能找到。 19 | 20 | ##### BottomNavigationBar 21 | 22 | BottomNavigationBar 在 items 里面添加想要的 BottomNavigationBarItem，然后 currentIndex 代表当前 item, page 在 PageView 的 onPageChanged()更改。 23 | 24 | ``` 25 | bottomNavigationBar: new BottomNavigationBar(items: [ 26 | new BottomNavigationBarItem( 27 | icon: new Icon(FontAwesomeIcons.font), 28 | title: new Text("Text"), 29 | backgroundColor: Colors.grey 30 | ), 31 | //更多 BottomNavigationBarItem 32 | ], 33 | onTap: onTap, 34 | currentIndex: page 35 | ), 36 | ``` 37 | 38 | ##### 改变页面切换时候的动画效果 39 | 看 onTap 方法，其中改变 curve 可以改变页面切换时候的动画效果，可以点进 curves,dart 里面看看，有挺多种方法，尝试了一下，还是 Curves.ease 是一种最让人舒服的动画。 然后 duration 可以设置动画时间，可以尝试设置成 1000，你会发现切换页面，嗯，很慢。 40 | 41 | ``` 42 | void onTap(int index) { 43 | pageController.animateToPage( 44 | index, 45 | // 设置页面转换效果的时间 46 | duration: const Duration(milliseconds: 300), 47 | // 设置转换时的效果 48 | curve: Curves.ease); 49 | } 50 | ``` 51 | 52 | ##### PageView 53 | 54 | 然后是 PageView：用把子页面放到 children 里面(这里Page1() 什么的是为了简化篇幅，实际上没这个 class)，然后用一个 pageController 来监听页面切换，可以上面的代码里就有 pageController 来控制页面和转换效果。用 onPageChanged 监听页面切换，执行页面切换以后的要执行的操作。 55 | 56 | ``` 57 | body: new PageView( 58 | children: [ 59 | new Page1(), 60 | new Page2(), 61 | new Page3(), 62 | ], 63 | controller: pageController, 64 | onPageChanged: onPageChanged, 65 | ), 66 | ``` 67 | 用 onPageChanged 监听页面切换，切换后设置当前 page 值。 68 | 69 | ``` 70 | void onPageChanged(int page) { 71 | setState(() { 72 | this.page = page; 73 | }); 74 | } 75 | ``` 76 | ##### 设置起始子页面： 77 | 78 | ``` 79 | @override 80 | void initState() { 81 | super.initState(); 82 | // 设置初始化page 83 | pageController = new PageController(initialPage: this.page); 84 | } 85 | ``` 86 | 87 | #### 顶部导航栏（Part2） 88 | 89 | 用 AppBar 实现，用 title 设置顶部 bar 的文字，bottom用 TabBar 设置导航栏的图标，然后界面上在 TabBarView 里面完成不同的 subpage。 90 | 91 | ``` 92 | new AppBar( 93 | title: Text('TopBarPage'), 94 | bottom: new TabBar( 95 | tabs: [ 96 | new Tab( 97 | icon: new Icon(FontAwesomeIcons.google), 98 | ), 99 | new Tab( 100 | icon: new Icon(FontAwesomeIcons.facebook), 101 | ), 102 | ], 103 | controller: _tabController, 104 | ), 105 | ), 106 | body: new TabBarView( 107 | controller: _tabController, 108 | children: [ 109 | new Center(child: new Text('Google',style: TextStyle(fontSize: 20,),)), 110 | new Center(child: new Text('Facebook',style: TextStyle(fontSize: 20,),)), 111 | ], 112 | ), 113 | ``` 114 | 115 | #### 其他 116 | 117 | 刚刚在油管上浏览，看到 Flutter 又出新视频，上面有用 Cupertino Package 实现 iOS 风格的导航栏，有兴趣也可以看一下。 118 | 119 | [https://www.youtube.com/watch?v=3PdUaidHc-E](https://www.youtube.com/watch?v=3PdUaidHc-E) 120 | 121 | ### Flutter 学习之路 Github 地址 122 | 123 | 这是项目的 GitHub 地址，正在持续更新，欢迎

Flutter 学习之路 - 网络入门 2 | > 实验一些 Flutter 的网络方面的功能 （[代码Github地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day11.dart)） 3 | 4 | ### 概述 5 | 6 | 一开始在想标题要叫什么呢，想想网络是个很复杂的东西，这里就实验了最基本的，开发过程中最常用的 Get Post, 就叫网络入门吧哈哈。 7 | 8 | Flutter 现在常用的网络方式有如下三种： 9 | 10 | - HttpClient 11 | - http 12 | - dio 13 | 14 | 这里试验了三种方法的 GET,POST 方法，以及 JSON 的解析。 15 | 16 | 实现通过 ip 获取 ip 所在地信息等方法。 17 | 18 | 19 | [代码地址](https://github.com/draftbk/flutter_road/blob/master/flutter_road_widgets/lib/days/Day11.dart) 20 | 21 | ![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_network.gif) 22 | 23 | 本次试验 url: 24 | 25 | ```Dart 26 | String getUrl="https://httpbin.org/ip"; 27 | String postUrl="http://ip.taobao.com/service/getIpInfo.php"; 28 | String searchIp='117.89.35.58'; 29 | ``` 30 | 分别是获取 ip(虽然我觉得它获取的ip 很奇怪)，以及通过 ip 获取 ip 的所在地以及其他信息。 31 | 32 | 为了方便，第二个url 要用的 ip 设定为一个固定值。 33 | 34 | ### 用 HttpClient 实现 35 | HttpClient 是 Dart 原生的网络请求，flutter 中文网上的 cookbook 是用这个来实现的 36 | 37 | 不需要在 pubspec.yaml 添加依赖 38 | 39 | 引入： 40 | 41 | ```Dart 42 | import 'dart:convert'; 43 | import 'dart:io'; 44 | ``` 45 | 46 | #### GET 请求 47 | 48 | ```Dart 49 | void HttpClient_Get() async { 50 | var httpClient = new HttpClient(); 51 | String result; 52 | try { 53 | var request = await httpClient.getUrl(Uri.parse(getUrl)); 54 | var response = await request.close(); 55 | if (response.statusCode == HttpStatus.OK) { 56 | result = await response.transform(utf8.decoder).join(); 57 | } else { 58 | result = 59 | 'Error getting IP address:\nHttp status ${response.statusCode}'; 60 | } 61 | } catch (exception) { 62 | result = 'Failed getting IP address'; 63 | } 64 | } 65 | ``` 66 | 67 | #### POST 请求 68 | 69 | 网上找没有，然后对应着官网 API 尝试用了下面这个方法还是失败， 不清楚为什么，如果有同学找到方法解决求告知一下！ 70 | 71 | ```Dart 72 | Uri uri=new Uri(path:postUrl,queryParameters: {"ip": searchIp} ); 73 | var request = await httpClient.postUrl(uri); 74 | var response = await request.close(); 75 | ``` 76 | 其他两个方法 POST 都可以，umm, 而且功能还更全，所以还是用另外两种方法吧！ 77 | 78 | ### 用 http 实现 79 | flutter 官网上的 cookbook 是用这个来实现的 80 | 81 | 不需要在 pubspec.yaml 添加依赖 82 | 83 | 引入： 84 | 85 | ```Dart 86 | import 'package:http/http.dart' as http; 87 | ``` 88 | 89 | #### GET 请求 90 | 91 | ```Dart 92 | void http_Get() async { 93 | String result; 94 | try { 95 | var response = await http.get(getUrl); 96 | if (response.statusCode == HttpStatus.OK) { 97 | result = response.body; 98 | } else { 99 | result = 100 | 'Error getting IP address:\nHttp status ${response.statusCode}'; 101 | } 102 | } catch (exception) { 103 | result = 'Failed getting IP address'; 104 | } 105 | } 106 | ``` 107 | 108 | #### POST 请求 109 | 110 | ```Dart 111 | void http_Post() async { 112 | String result; 113 | try { 114 | 115 | var client = http.Client(); 116 | var response = await client.post(postUrl, body: {"ip": searchIp}); 117 | 118 | if (response.statusCode == HttpStatus.OK) { 119 | result = response.body; 120 | } else { 121 | result = 122 | 'Error getting IP address:\nHttp status ${response.statusCode}'; 123 | } 124 | } catch (exception) { 125 | result = 'Failed getting IP address'; 126 | } 127 | } 128 | ``` 129 | 130 | ### 用 dio 实现 131 | 132 | dio是Flutter中文网开源的一个强大的Dart Http请求库，支持Restful API、FormData、拦截器、请求取消、Cookie管理、文件上传/下载、超时等 133 | 134 | 需要在 pubspec.yaml 添加依赖 **dio: any** 135 | 136 | ```Dart 137 | dependencies: 138 | flutter: 139 | sdk: flutter 140 | dio: any 141 | ``` 142 | 143 | 引入： 144 | 145 | ```Dart 146 | import 'package:dio/dio.dart'; 147 | ``` 148 | 149 | 150 | #### GET 请求 151 | 152 | ```Dart 153 | void dio_Get() async { 154 | String result; 155 | try { 156 | Dio dio = new Dio(); 157 | var response = await dio.get(getUrl); 158 | if (response.statusCode == HttpStatus.OK) { 159 | result = response.data.toString(); 160 | } else { 161 | result = 162 | 'Error getting IP address:\nHttp status ${response.statusCode}'; 163 | } 164 | } catch (exception) { 165 | result = 'Failed getting IP address'; 166 | } 167 | } 168 | ``` 169 | 170 | #### POST 请求 171 | 172 | ```Dart 173 | void dio_Post() async { 174 | String result=""; 175 | try { 176 | var dio = new Dio(); 177 | var response = await dio.post(postUrl, queryParameters:{"ip": searchIp}); 178 | if (response.statusCode == HttpStatus.OK) { 179 | result = response.data.toString(); 180 | } else { 181 | result = 182 | 'Error getting IP address:\nHttp status ${response.statusCode}'; 183 | } 184 | } catch (exception) { 185 | result = 'Failed getting IP address'; 186 | } 187 | } 188 | ``` 189 | 190 | #### 其他 191 | 192 | dio 还有好多方法，可以看看这个链接： 193 | [https://pub.dartlang.org/packages/dio](https://pub.dartlang.org/packages/dio) 194 | 195 | ### JSON 解析 196 | 197 | 就直接用下面的方法就可以解析了，真的很方便 198 | 199 | ```Dart 200 | var data = json.decode(result); 201 | result = data['origin']; 202 | ``` 203 | 204 | 205 | ### Flutter 学习之路 Github 地址 206 | 207 | 这是项目的 GitHub 地址，正在持续更新，欢迎 Star 呀！╮(￣▽￣)╭ 208 | 209 |

![](https://github.com/draftbk/Blog_Resource/blob/master/Flutter/gif/flutter_road_text.gif) 21 | 22 | 23 | #### Text Style 属性 24 | 25 | 感觉Text的前面的一些地方都是通过改 Text 的属性，可以直接进入我的代码地址看代码看懂的，这边就放一个属性表。 26 | 27 | | 属性 | 意义 | 28 | | ---------- | ----------- | 29 | | fontSize | 文字大小 | 30 | | fontWeight | 文字粗细 | 31 | | color | 文字颜色 | 32 | | fontFamily | 字体 | 33 | | fontStyle | 文字风格（可以设置斜体） | 34 | | wordSpacing | 单词之间的间隙 | 35 | | letterSpacing |字母之间的间隙 | 36 | | locale |区域设置 | 37 | | decoration | 文字装饰（例如下划线，上划线，划去的效果） | 38 | | decorationStyle |文字装饰的风格（例如我上面代码实现的波浪线） | 39 | | decorationColor |文字装饰的颜色 | 40 | 41 | #### 文本点击 42 | 点击事件改变自己参数的时候要用 setState， 不然直接改 _tapText 界面并不会有反应。 43 | 44 | ``` 45 | Padding( 46 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 47 | child: GestureDetector( 48 | onTap: () { 49 | setState(() { 50 | if(_tapText=="啊我被点到了"){ 51 | _tapText="文字点击事件, 点我！"; 52 | }else{ 53 | _tapText="啊我被点到了"; 54 | } 55 | }); 56 | }, 57 | child: Text( 58 | _tapText, 59 | style: TextStyle( 60 | fontSize: 16, 61 | fontWeight: FontWeight.bold, 62 | ), 63 | ), 64 | ), 65 | ), 66 | ``` 67 | 68 | #### 文本拼接 69 | 70 | 拼接效果可以看上面的动图，感觉拼接是一个很有趣的功能，可以在一段文字里实现不同的功能，或者不同的点击，感觉例如一个英文文档，可以点击不同的文字获取不同的中文翻译这样的功能可以这样实现。 71 | 72 | ``` 73 | // 文本拼接 74 | Padding( 75 | padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 0.0), 76 | child: Text.rich( 77 | new TextSpan( 78 | text: '文字拼接: ', 79 | style: new TextStyle( 80 | color: Colors.black, 81 | fontSize: 14, 82 | decoration: TextDecoration.none), 83 | children: [ 84 | new TextSpan( 85 | text: "文字一", 86 | style: new TextStyle( 87 | color: Colors.blue, 88 | fontSize: 20, 89 | decoration: TextDecoration.none)), 90 | new TextSpan( 91 | text: "文字二", 92 | style: new TextStyle( 93 | color: Colors.green, 94 | fontSize: 14, 95 | decoration: TextDecoration.none)), 96 | new TextSpan( 97 | text: "文字三", 98 | style: new TextStyle( 99 | color: Colors.red, 100 | fontSize: 18, 101 | decoration: TextDecoration.none)), 102 | ]), 103 | ), 104 | ) 105 | ``` 106 | 107 | #### Flutter 学习之路 Github 地址 108 | 109 |
