Flutter的SDK国内下载方法及AndroidStudio配置打包方法

打开官方网站版本归档列表:https://docs.flutter.dev/install/archive
在蓝色的版本号(即有链接),如2.10.0上,右键,复制链接地址如下
https://storage.googleapis.com/flutter_infra_release/releases/stable/windows/flutter_windows_2.10.0-stable.zip
更换头部地址https://storage.googleapis.com为镜像地址https://storage.flutter-io.cn

即国内下载:
https://storage.flutter-io.cn/flutter_infra_release/releases/stable/windows/flutter_windows_2.10.0-stable.zip

https://storage.flutter-io.cn/flutter_infra_release/releases/stable/windows/flutter_windows_2.10.5-stable.zip

Androidstudio配置:
settings
Dart: D:\software\flutter_2.10.5\flutter\bin\cache\dart-sdk

打包方法:
命令行进入项目目录
如果项目flutter版本与环境变量不一样则使用精确路径调用flutter批处理命令,例如:
D:\software\flutter_3.3.0\flutter\bin\flutter.bat build apk --release
上面打包的是全soc架构通用的,体积比较大
如果不用兼容arm 32位及x86架构,则可以加如下参数
D:\software\flutter_3.3.0\flutter\bin\flutter.bat build apk --release --split-per-abi
会分成3个包
app-armeabi-v7a-release.apk # 32 位 ARM 老款/低端设备
app-arm64-v8a-release.apk # 64 位 ARM，现代手机主流（2020 年后基本全是,覆盖95%设备）
app-x86_64-release.apk # x86 64 位，主要是模拟器和少数特殊设备
