下载安装并配置flutter

1.去github上下载flutter安装包

https://github.com/flutter/flutter/releases/tag/2.0.4

2.将安装包zip解压到你想安装Flutter SDK的路径

&＃xff08;如&＃xff1a;C:\src\flutter&＃xff1b;注意&＃xff0c;不要将flutter安装到需要一些高权限的路径如C:\Program Files\&＃xff09;

3.配置系统环境变量和用户环境变量

&＃xff08;1&＃xff09;用户环境变量&＃xff1a;
PUB_HOSTED_URL&＃xff1a;https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL&＃xff1a;https://storage.flutter-io.cn
&＃xff08;2&＃xff09;系统环境变量
在PATH里&＃xff1a;添加一个你解压缩好的flutter\bin的全路径

4.在你解压缩的文件夹里用git命令行执行一条命令&＃xff1a;

git clone -b beta https://github.com/flutter/flutter.git
如图&＃xff1a;



这样就下载成功

5.进入用git下载命令下载的flutter文件夹&＃xff0c;找到这个双击打开命令行&＃xff0c;输入PowerShell,再输入flutter doctor.
