用你最擅长的技术去对接新知识， 85 | 比如你是个天文迷，如果你想学英语，去看天文方面的读物会更有利， 86 | 因为你有这方面的知识储备，即使知识储备是中文又如何?难道英文的地球能出太阳系? 87 | 语言和知识本就是两码事，语言表述知识并不会更改知识本身。 88 | 所以知识对接上，两种语言之间的交错，会让你更快接受语言的本身，也能强化知识 89 | ``` 90 | 91 | --- 92 | 93 | ``` 94 | 所以我并没有一开始就上控件，而是基于我最熟悉的Canvas来绘图，熟悉Dart语法，否则后面工作不好开展， 95 | 在Android中Canvas的丰富知识储备让我很好的与Flutter中的Canvas对接,这一棋自认为不错 96 | 对接之后，以前画网格，坐标系，n角星的东西又能拿出来秀了，旧知识转化成新知识 97 | 通过Java代码更改成Dart代码，也让我更清楚了两者的异同点，以后把握起来就轻松写 98 | ``` 99 | 100 | >总的来说第一天还是蛮轻松好玩的。 101 | 102 | --- 103 | 104 | ##### 第二天及体悟： 105 | 106 | ``` 107 | 第二天可以说是兵行险招，本打算把基础控件说一下的(依稀听过Flutter的控件超级多) 108 | 但第一天图画好之后，非常想玩动画，如果放在后面，感觉不连贯 109 | 然而并没有把握把动画写好，毕竟才更接触一天而已。挑战一下呗，然后就玩动画了 110 | ``` 111 | 112 | 113 | ``` 114 | 第二天可以说是这七天里我感觉最成功的，动画+粒子运动全都复刻到Flutter上了 115 | 粒子时钟完成后，挺激动的,然后就拿去分(xian)享(bai),心想，Flutter还是不错的嘛 116 | 这绝对是Flutter的第一个粒子时钟(除了我，也许没有人会这么无聊做这种特效) 117 | ``` 118 | 119 | 120 | ``` 121 | 看上去第二天的文章好像一气呵成，其实也遇到了些阻碍， 122 | dart的时间处理和三维数组和Java有些出入，还有就是时钟的粒子运动， 123 | 差一点就放弃了，因为效果总是出不来。心想，搞出个时钟就算了吧，不也挺好嘛。 124 | 可是真的很不甘心，都到这步了。然后输出小球集合的个数、第一个小球的位置， 125 | 数据好好的啊，可为什么出不来效果……最后发现小球半径没有设置……出来才有鬼呢 126 | ``` 127 | 128 | 129 | 130 | ``` 131 | 有人问我有没有什么心得，心得这东西说出来都懂，做起来却不简单， 132 | 如果你觉得一个人的学习方式很好，你应该去观察他，然后取长补短。 133 | 每个人的境遇都是不同的，别人的学习方法不一定适合你，你没有必要和别人一样。 134 | 比如我大学喜欢写诗，然后通读各大名著，不断思考世界，如果你没有这些基础， 135 | 我的心得就不一定适合你。每个人的价值观也是不同的，我是更倾向提升自我境界的那种人， 136 | 物质并不多求。心得这东西，别人的都是废话，需要的话，网上鸡汤自己挑， 137 | 一般人豪言壮语，大多只是自欺欺人。最近看到八个字挺实在:"生死看淡，不服就干"。 138 | ``` 139 | 140 | >总的来说第二天收获颇丰。 141 | 142 | --- 143 | 144 | ##### 第三、四天及体悟： 145 | 146 | ``` 147 | 第三天基础控件，感觉应该很枯燥，所以我尽可能让它变得有趣 148 | 我喜欢画体系的树状图，因为这样看起来很清晰，也助于整理思路 149 | 我喜欢卡片，源于游戏王，对于繁多的事物，感觉用卡片记录一下比较有趣 150 | ``` 151 | 152 | 153 | --- 154 | 155 | ``` 156 | 第三天源码翻得比较多，基本上是进去看控件属性，代码测试 157 | 通过Android和html+css的布局经验，基本上套路都是那回事 158 | 而且Flutter的Flex布局和css的flex布局不谋而合，所以入手容易很多 159 | 遇到margin的时候，有点感触，写了点看到新东西的态度: 160 | 161 | 新事物往往都与旧事物有联系,学习新事物最好快速找到它与你知识库中旧事物的联系, 162 | 联系的多少取决于你知识库中内容的多少，连接得越多，你会越快或越能掌握旧事物 163 | ``` 164 | 165 | --- 166 | 167 | ``` 168 | 本以为第四天可以把剩余的控件讲完，再写几个小案例呢，万万没想到: 169 | Flutter的布局如此之多，再加上卡了一点小壳，只勉强把控件了结(实际上还有很多未涉及) 170 | Flutter里面29种叠合模式也是吓到我了，也借此分析了一下这种多情况的分析方式 171 | 第三天把我的激情燃烧殆尽，第四天，三个控件一组，一共六组18张，没那么多花哨 172 | 最后将Flex布局详细说明了一下 173 | ``` 174 | 175 | --- 176 | 177 | 178 | ``` 179 | 这两天难度不是很大，就是有点麻烦，画图，配卡什么的， 180 | 只是敲代码的估计一天就够了，不过那样会及其无聊，不是我想要的 181 | 第四天写到最后其实还是有不少控件没涉及到呢，但感觉也就那回事 182 | 认识一个控件可就那点套路，属性基本上也就那些，遇到新的看看也就明白了 183 | 没有必要全部列出来，这就是"鱼与渔"的区别吧，鱼是抓不完的，你也放不下 184 | ``` 185 | 186 | --- 187 | 188 | 189 | ``` 190 | 两条源码翻得比较勤，有点小感悟： 191 | 192 | 有问题就去解决，即使牵涉出十个新问题，你就想象成问题栈， 193 | 有问题就进栈，解决了就出栈，这样不会乱，你可见的就是栈顶而已， 194 | 一个一个来，这样会相对于11个问题摆在你面前更容易接受。 195 | 至于什么时候stackover（栈溢出）就看你的决心和耐力了。 196 | 当然新手感觉hold不住时，可以深呼吸，咬一下牙坚持一下。 197 | 还是不行的话，记录下问题，果断退出。也许你现在等级不够， 198 | 这个boss你打不过，那就去刷怪升级吧。短剑重铸之日，骑士归来之时。 199 | 现在回头来看以前困扰我的问题，其实也并没有什么，这样你才能感觉成长 200 | ``` 201 | 202 | >总的来说第三、四天挺苦闷，但也是必经之路 203 | 204 | --- 205 | 206 | ##### 第五、六、七天及体悟： 207 | 208 | ``` 209 | 经过前四天，基本上语法、控件也就熟悉了，接下来统一说一下： 210 | 第五天可以说非常有料，网上很少有详细分析Flutter怎么布局的 211 | 中文网的例子有点小复杂，我打算循序渐进地由简到难进行陈述 212 | 首先是最简单的条目入手一步步递进成掘金的条目， 213 | 交互操作看似很多，其实常用的也就那几个，操作也是widget这点非常有趣 214 | 215 | ``` 216 | 217 | ``` 218 | 第六天Dart的io,以及网络和json的处理，这是一门语言的基础 219 | Java和Python还有node的io有所接触，所以dart这方面并不麻烦 220 | 但一在Flutter上，路径不好拿，背景是跨平台，还好有三根救命稻草：`path_provider` 221 | 然后是权限问题，当然也有相应的依赖库`simple_permissions`， 222 | 网络库用起来比较简单,基本上和前端的网络库操作一致 223 | ``` 224 | 225 | 226 | ``` 227 | 第七天是前六天的知识整合，并扫一下其他小的知识点 228 | Flutter与安卓的原生交互让我感觉它还是蛮好的，虽然有点麻烦 229 | 不过要跨平台，只与Android交互只是有半壁江山，ios那块就不好办了 230 | 虽说Flutter可以跨平台，但如果要玩得转，需要一个人兼具Android和ios 231 | 这样算来，这个跨平台代价还是有的，你也许会说，有插件包啊 232 | 但是插件包只能解决一部分问题，各种业务千差万别，如果只靠插件包，有点牵强 233 | 毕竟有些逻辑上的小修小补，具体问题框架无能为力，只能"凑合用" 234 | Flutter是一个很好的UI框架，但可操作性，略有不足 235 | ``` 236 | 237 | --- 238 | 239 | ##### 结束语 240 | 241 | ``` 242 | React玩的好的人入手Flutter可以说会轻松很多，因为思想非常相似 243 | 任何人都会有不足，不可能对这个世界全识全知，也就是"术业有专攻" 244 | 但并不意味这要闭关锁国，排斥外物。程序员读读诗，看看史也没有什么不可 245 | 多看星空方知何谓渺小，多看细胞方知何谓浩大，你是巨人也是沙，崇高并谦卑着 246 | 程序源于对这个世界的认知，何为境界，你眼中所视之物，究竟为何? 247 | 学无止境，不要飘，脚踏实地，一步一印，殊途同归，新即远方，思之将至。 248 | ``` 249 | 250 | --- 251 | 252 | ##### 最后插播一段感悟：我经常思考工具与使用者间的关系: 253 | 254 | 255 | ``` 256 | `用工具`和`会用工具`之差异:[良庖岁更刀，割也；族庖月更刀，折也], 257 | 工具的使用方法体现了一位`工匠`的技艺 258 | 259 | 《庖丁解牛》是我最喜欢的一篇古文，如何在做任何事上: 260 | [以无厚入有间，恢恢乎其于游刃必有余地矣]是我的思考 261 | 262 | 文中的八字成为我接触新事物的律典：[依乎天理，因其固然]。 263 | 通其理，方用之，是`匠者`与`匠师`的差异 264 | 265 | 如果你不懂牛的构造原理，拿一把屠刀固然可杀牛取肉， 266 | 但庖丁的[以神遇而不以目视，官知止而神欲行] 267 | [提刀而立，为之四顾，为之踌躇满志，善刀而藏之]感觉也就与你无缘， 268 | 而这是一位匠者的自豪。 269 | 270 | 写一个程序就像打造一件艺术品，制造的过程便是`解牛`， 271 | IDE、API、运行环境就是我手中的剑 272 | 273 | 普通屠夫遇牛则斩，好肉坏肉在一起切，煮成一大杂烩。 274 | 庖丁的匠心独运是我追求的境界: 275 | [吾生也有涯，而知也无涯,以有涯随无涯] 愿君且行且珍惜。 276 | ``` 277 | 278 | -------------------------------------------------------------------------------- /android/app/build.gradle: -------------------------------------------------------------------------------- 1 | def localProperties = new Properties() 2 | def localPropertiesFile = rootProject.file('local.properties') 3 | if (localPropertiesFile.exists()) { 4 | localPropertiesFile.withReader('UTF-8') { reader -> 5 | localProperties.load(reader) 6 | } 7 | } 8 | 9 | def flutterRoot = localProperties.getProperty('flutter.sdk') 10 | if (flutterRoot == null) { 11 | throw new GradleException("Flutter SDK not found.
