Flutter环境搭建
-
配置环境变量
用户变量
FLUTTER_STORAGE_BASE_URL : https://storage.flutter-io.cn
PUB_HOSTED_URL : https://pub.flutter-io.cn
由于是在国内，所以需要配置一个可靠的镜像站点，也可以选择清华大学TUNA
FLUTTER_STORAGE_BASE_URL: https://mirrors.tuna.tsinghua.edu.cn/flutter
PUB_HOSTED_URL: https://mirrors.tuna.tsinghua.edu.cn/dart-pub

获取Flutter SDK
下载链接：https://flutter.dev/docs/development/tools/sdk/releases#windows
可以直接下载SDK然后解压，也可以从github下载，目前最新版v1.12.13+hotfix.7
在系统变量中编辑用户变量的Path条目，添加flutter SDK的bin目录
Path : D:\flutter\sdk\bin
