获取 Flutter SDK
- 使用
git去克隆仓库 - 添加
flutter工具到环境变量 - 运行
flutter doctor来显示剩下你需要安装的的依赖。
克隆仓库
如果这是你第一次在电脑上安装 Flutter ，需要克隆这个远程仓库：
$ git clone -b beta https://github.com/flutter/flutter.git
D:\>git clone -b beta https://github.com/flutter/flutter.git
Cloning into 'flutter'...
remote: Counting objects: 128732, done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 128732 (delta 0), reused 0 (delta 0), pack-reused 128729
Receiving objects: 100% (128732/128732), 40.15 MiB | 500.00 KiB/s, done.
Resolving deltas: 100% (96845/96845), done.
Checking out files: 100% (2543/2543), done.
要更新现有版本的 Flutter ，参阅 升级 Flutter
更新你的环境变量
- 打开 “控制面板 > 系统和安全 > 系统 > 高级系统设置 > 环境变量”。
- 在 Path 变量末尾添加
;并且加上flutter\bin的全路径。
运行 flutter doctor
打开一个新的命令提示符运行以下的命令，看是否需要安装依赖项来完成安装：
$ flutter doctor
你可能会遇到下载不下来的情况，只需添加如下两对键值到环境变量中再次运行即可：

FLUTTER_STORAGE_BASE_URL
https://storage.flutter-io.cn

PUB_HOSTED_URL
https://pub.flutter-io.cn
PUB_HOSTED_URL和FLUTTER_STORAGE_BASE_URL是谷歌的国内临时镜像。
接下来运行flutter doctor
D:\>flutter doctor
