flutter 5 | - node.js环境 下载：https://nodejs.org/zh-cn/ 下好安装即可，很简单 6 | - npm包管理工具(Node自带) 7 | 8 | # fmaker功能 9 | 10 | 11 | 12 | fmaker是一个flutter辅助图片处理工具，也可以用来给iOS或Android项目生成图标 13 | 14 | 指令帮助： 15 | ```bash 16 | fmaker -h 17 | Usage: fmaker [options] [command] 18 | 19 | Options: 20 | -V, --version output the version number 21 | -h, --help display help for command 22 | 23 | Commands: 24 | init 在一个Flutter项目中初始化tmaker，为你创建文件夹，添加示例文件和添加.gitignore参数 25 | build [parts] 创建资源，可指定创建指定部分，例: fmaker build ios,android,assets 26 | preview 仅创建资源的预览注释，也就是r.preview.dart文件 27 | folder 把app的图标渲染在本项目的文件夹上(仅mac) 28 | help [command] display help for command 29 | ``` 30 | 31 | ### 按倍率生成图片 32 | `fmaker`可以自动识别项目下`/assets/fmaker`中的多倍图，将多倍图按flutter格式递归转换为2.0x，3.0x，4.0x等文件夹，再将压缩后的低倍图保存到assets中，保证flutter可以自动识别低倍率的图片。例如，在文件夹下放置`example@3x.png`，会生成三倍图，两倍图和一倍图。 33 | 34 | > 为什么要这样做？ 35 | 36 | 因为高分辨率的图片被缩小时，会产生不必要的锐化效果，偶尔会产生卡顿；小图被放大时，会变得很模糊，flutter提供一个功能，自动显示正确分辨率的图片。 37 | 但是使用这个功能困难重重，如果你的设计使用sketch切图，只能切出`image.png`,`image@2x.png`,`image@3x.png`这种图，但是flutter需要的图片目录格式是`image.png`,`2.0x/image.png`,`3.0x/image.png`，这种格式使用sketch是很难一次导出的（需要每一次都更改导出名称），很不好用。 38 | 39 | ### 生成App图标 40 | 41 | 如果`/assets/fmaker`文件夹下有名为`ios_icon.png`和`android_icon.png`的文件，那么`fmaker`会自动识别这两个文件，直接将图标生成到项目中，不需要额外的复制粘贴。 42 | 43 | > 注意：iOS的图标不可含有alpha通道，Android的图标可以包含。共同的一点是，图标必须是正方形，`fmaker`会帮你检查icon尺寸，并在log中输出错误。 44 | ### 生成文件夹图标 45 | 46 | 在项目目录下运行： 47 | 48 | ``` 49 | fmaker folder 50 | ``` 51 | 52 | 脚本会自动把Icon?加入.gitignore。 53 | 如下加入即可： 54 | ``` 55 | Icon? 56 | ``` 57 | ### 生成yaml引用与r.dart 58 | 59 | 为了方便`flutter`使用，现在会自动生成yaml的资源引用，你需要先添加： 60 | 61 | ```yaml 62 | flutter: 63 | uses-material-design: true 64 | assets: 65 | # 添加下面这一句 66 | # fmaker 67 | ``` 68 | 那么在运行`fmaker build`后，就会自动生成: 69 | ```yaml 70 | flutter: 71 | uses-material-design: true 72 | assets: 73 | # fmaker 74 | - assets/example.png 75 | # fmaker-end 76 | ``` 77 | 对应的，也会在lib目录下生成r.dart文件，变量名会自动转为驼峰形式 78 | ```dart 79 | class R { 80 | static final String aqweqAsqQweqDasQwr = 'assets/aqweq-asq_qweq-das_qwr.png'; 81 | static final String assfaAbAResize = 'assets/assfa(ab)a-resize.png'; 82 | static final String example = 'assets/example.png'; 83 | } 84 | ``` 85 | 86 | # 安装 87 | 88 | ```bash 89 | git clone https://github.com/mjl0602/flutter-assets-maker.git 90 | cd flutter-assets-maker 91 | npm install -g 92 | fmaker 93 | ``` 94 | 如果看到，“没有对应指令，fmaker已安装”的log，就已经安装成功。 95 | 96 | # 使用 97 | 先假定你的项目名叫yourFlutterProject。 98 | 99 | 需要准备icon文件，`ios_icon.png`和`ios_android.png`，放在yourFlutterProject/assets/fmaker下，其他的多倍图也可以放进去，例如example@3x.png。 100 | 101 | Tips:如果找不到合规的文件又想试一试，使用fmaker init来使用我的测试图片。 102 | 103 | ```bash 104 | cd yourFlutterProject 105 | fmaker init #如果暂时找不到图，就用我的图测试 106 | fmaker build 107 | ``` 108 | 然后安卓与iOS的App图标都已经被替换，你可以启动项目来查看。 109 | 110 | # 注意 111 | 112 | - 工具理论上只支持png。 113 | - 工具会产生两个一样的图，一个是最高倍图，一个是源图，一定程度上增加了项目大小。 114 | - 建议不要引用fmaker文件夹中的源图，因为他不能被自动切换倍率。 115 | - fmaker的重复图片不会增加产物大小，只要你不引入源图。 116 | 117 | # 示例 118 | 119 | //TODO 120 | 有空就整个例子 121 | 122 | > 如果有bug，欢迎提issue，pr更好哦。 123 | > 仓库地址:https://github.com/mjl0602/flutter-assets-maker 124 | 125 | #未经作者授权，本文禁止转载 126 | 127 | 128 | -------------------------------------------------------------------------------- /assets/Contents.json: -------------------------------------------------------------------------------- 1 | { 2 | "images" : [ 3 | { 4 | "size" : "20x20", 5 | "idiom" : "iphone", 6 | "filename" : "Icon-App-20x20@2x.png", 7 | "scale" : "2x" 8 | }, 9 | { 10 | "size" : "20x20", 11 | "idiom" : "iphone", 12 | "filename" : "Icon-App-20x20@3x.png", 13 | "scale" : "3x" 14 | }, 15 | { 16 | "size" : "29x29", 17 | "idiom" : "iphone", 18 | "filename" : "Icon-App-29x29@1x.png", 19 | "scale" : "1x" 20 | }, 21 | { 22 | "size" : "29x29", 23 | "idiom" : "iphone", 24 | "filename" : "Icon-App-29x29@2x.png", 25 | "scale" : "2x" 26 | }, 27 | { 28 | "size" : "29x29", 29 | "idiom" : "iphone", 30 | "filename" : "Icon-App-29x29@3x.png", 31 | "scale" : "3x" 32 | }, 33 | { 34 | "size" : "40x40", 35 | "idiom" : "iphone", 36 | "filename" : "Icon-App-40x40@2x.png", 37 | "scale" : "2x" 38 | }, 39 | { 40 | "size" : "40x40", 41 | "idiom" : "iphone", 42 | "filename" : "Icon-App-40x40@3x.png", 43 | "scale" : "3x" 44 | }, 45 | { 46 | "size" : "60x60", 47 | "idiom" : "iphone", 48 | "filename" : "Icon-App-60x60@2x.png", 49 | "scale" : "2x" 50 | }, 51 | { 52 | "size" : "60x60", 53 | "idiom" : "iphone", 54 | "filename" : "Icon-App-60x60@3x.png", 55 | "scale" : "3x" 56 | }, 57 | { 58 | "size" : "20x20", 59 | "idiom" : "ipad", 60 | "filename" : "Icon-App-20x20@1x.png", 61 | "scale" : "1x" 62 | }, 63 | { 64 | "size" : "20x20", 65 | "idiom" : "ipad", 66 | "filename" : "Icon-App-20x20@2x.png", 67 | "scale" : "2x" 68 | }, 69 | { 70 | "size" : "29x29", 71 | "idiom" : "ipad", 72 | "filename" : "Icon-App-29x29@1x.png", 73 | "scale" : "1x" 74 | }, 75 | { 76 | "size" : "29x29", 77 | "idiom" : "ipad", 78 | "filename" : "Icon-App-29x29@2x.png", 79 | "scale" : "2x" 80 | }, 81 | { 82 | "size" : "40x40", 83 | "idiom" : "ipad", 84 | "filename" : "Icon-App-40x40@1x.png", 85 | "scale" : "1x" 86 | }, 87 | { 88 | "size" : "40x40", 89 | "idiom" : "ipad", 90 | "filename" : "Icon-App-40x40@2x.png", 91 | "scale" : "2x" 92 | }, 93 | { 94 | "size" : "76x76", 95 | "idiom" : "ipad", 96 | "filename" : "Icon-App-76x76@1x.png", 97 | "scale" : "1x" 98 | }, 99 | { 100 | "size" : "76x76", 101 | "idiom" : "ipad", 102 | "filename" : "Icon-App-76x76@2x.png", 103 | "scale" : "2x" 104 | }, 105 | { 106 | "size" : "83.5x83.5", 107 | "idiom" : "ipad", 108 | "filename" : "Icon-App-83.5x83.5@2x.png", 109 | "scale" : "2x" 110 | }, 111 | { 112 | "size" : "1024x1024", 113 | "idiom" : "ios-marketing", 114 | "filename" : "Icon-App-1024x1024@1x.png", 115 | "scale" : "1x" 116 | } 117 | ], 118 | "info" : { 119 | "version" : 1, 120 | "author" : "xcode" 121 | } 122 | } 123 | -------------------------------------------------------------------------------- /assets/back.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mjl0602/flutter-assets-maker/fd1ab536c09496f8bf2599033f90b71cb2e24f18/assets/back.png -------------------------------------------------------------------------------- /assets/example@3x.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mjl0602/flutter-assets-maker/fd1ab536c09496f8bf2599033f90b71cb2e24f18/assets/example@3x.png -------------------------------------------------------------------------------- /assets/fileicon: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bash 2 | 3 | ### 4 | # Home page: https://github.com/mklement0/fileicon 5 | # Author: Michael Klement (http://same2u.net) 6 | # Invoke with: 7 | # --version for version information 8 | # --help for usage information 9 | ### 10 | 11 | # --- STANDARD SCRIPT-GLOBAL CONSTANTS 12 | 13 | kTHIS_NAME=${BASH_SOURCE##*/} 14 | kTHIS_HOMEPAGE='https://github.com/mklement0/fileicon' 15 | kTHIS_VERSION='v0.2.4' # NOTE: This assignment is automatically updated by `make version VER=` -

that is, you 554 | can only assign custom icons to regular files and folders, not to symlinks 555 | to them. 556 | 557 | `` can be an image file of any format supported by the system. 558 | It is converted to an icon and assigned to ``. 559 | If you omit ``, `` must itself be an image file whose 560 | image should become its own icon. 561 | 562 | `` specifies the file to extract the custom icon to: 563 | Defaults to the filename of `` with extension `.icns` appended. 564 | If a value is specified, extension `.icns` is appended, unless already present. 565 | Either way, extraction fails if the target file already exists; use `-f` to 566 | override. 567 | Specify `-` to extract to stdout. 568 | 569 | Command `test` signals with its exit code whether a custom icon is set (0) 570 | or not (1); any other exit code signals an unexpected error. 571 | 572 | **Options**: 573 | 574 | * `-f`, `--force` 575 | When getting (extracting) a custom icon, forces replacement of the 576 | output file, if it already exists. 577 | 578 | * `-q`, `--quiet` 579 | Suppresses output of the status information that is by default output to 580 | stdout. 581 | Note that errors and warnings are still printed to stderr. 582 | 583 | ## NOTES 584 | 585 | Custom icons are stored in extended attributes of the HFS+ filesystem. 586 | Thus, if you copy files or folders to a different filesystem that doesn't 587 | support such attributes, custom icons are lost; for instance, custom icons 588 | cannot be stored in a Git repository. 589 | 590 | To determine if a give file or folder has extended attributes, use 591 | `ls -l@ `. 592 | 593 | When setting an image as a custom icon, a set of icons with several resolutions 594 | is created, with the highest resolution at 512 x 512 pixels. 595 | 596 | All icons created are square, so images with a non-square aspect ratio will 597 | appear distorted; for best results, use square imges. 598 | 599 | ## STANDARD OPTIONS 600 | 601 | All standard options provide information only. 602 | 603 | * `-h, --help` 604 | Prints the contents of the synopsis chapter to stdout for quick reference. 605 | 606 | * `--man` 607 | Displays this manual page, which is a helpful alternative to using `man`, 608 | if the manual page isn't installed. 609 | 610 | * `--version` 611 | Prints version information. 612 | 613 | * `--home` 614 | Opens this utility's home page in the system's default web browser. 615 | 616 | ## LICENSE 617 | 618 | For license information and more, visit the home page by running 619 | `fileicon --home` 620 | 621 | EOF_MAN_PAGE 622 | -------------------------------------------------------------------------------- /assets/folder.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mjl0602/flutter-assets-maker/fd1ab536c09496f8bf2599033f90b71cb2e24f18/assets/folder.png -------------------------------------------------------------------------------- /assets/ic_launcher.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mjl0602/flutter-assets-maker/fd1ab536c09496f8bf2599033f90b71cb2e24f18/assets/ic_launcher.png -------------------------------------------------------------------------------- /assets/ios.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mjl0602/flutter-assets-maker/fd1ab536c09496f8bf2599033f90b71cb2e24f18/assets/ios.png -------------------------------------------------------------------------------- /assets/shape.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mjl0602/flutter-assets-maker/fd1ab536c09496f8bf2599033f90b71cb2e24f18/assets/shape.png -------------------------------------------------------------------------------- /builder/flutter.js: -------------------------------------------------------------------------------- 1 | const sharp = require("sharp");
