Flutter开发环境搭建

避免国内被墙，设置镜像源：

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

Windows直接添加上述环境变量即可。

下载Flitter安装包：

https://flutter.io/docs/development/tools/sdk/archive#windows

下载后解压会生成flutter目录，运行目录下的bat文件：

flutter_console.bat

添加flutter环境变量：

#将路径添加到环境变量的Path中
flutter\bin

检查flutter依赖：

flutter doctor

经过检测后，会提示你缺失的环境：

[-] Android toolchain - develop for Android devices
    • Android SDK at D:\Android\sdk
    ✗ Android SDK is missing command line tools; download from https://goo.gl/XxQghQ
    • Try re-installing or updating your Android SDK,
      visit https://flutter.io/setup/#android-setup for detailed instructions.

环境无误后，启动AndroidStudio，安装flutter插件，重启后即可直接新建flutter项目。

附带命令：

#显示连接的设备
flutter devices
#运行项目
flutter run
#运行并检查错误
flutter run --verbose
#打包release
flutter build --release
flutter build apk
