下载对应系统SDK解压即可，比如解压到D:\flutter
配置环境变量
Flutter 默认仓库不能直接访问，需要配置国内代理地址，另外为了方便不同版本切换不用重新下载依赖，可以配置依赖缓存目录，默认缓存目录为SDK目录
| 用途 | 变量 | 值 |
|---|---|---|
| 基础库 | FLUTTER_STORAGE_BASE_URL | https://storage.flutter-io.cn |
| 依赖库 | PUB_HOSTED_URL | https://pub.flutter-io.cn |
| 依赖库缓存目录 | PUB_CACHE | %USERPROFILE%\.pub-cache |
环境变量 PATH 配置加入，SDK解压目录
| 变量 | 值 |
|---|---|
| FLUTTER_HOME | Flutter SDK路径\bin eg: D:\flutter
|
| PATH |
%FLUTTER_HOME%\bin %FLUTTER_HOME%\bin\cache\dart-sdk\bin
|
开发 Android 应用还需要配置 Android SDK，直接安装 Android Studio 根据引导下载即可（Android Studio安装可以跳过不需要手动配置）
Android Studio 国内下载地址
Android Studio 国外下载地址
| 变量 | 值 |
|---|---|
| ANDROID_HOME | Android SDK路径 eg: %USERPROFILE%\AppData\Local\Android\Sdk
|
| PATH |
%ANDROID_HOME%\tools%ANDROID_HOME%\tools\bin%ANDROID_HOME%\platform-tools
|
macOS / Linux
