flutter环境搭建教程

flutter环境搭建，可参考官网链接，此处以Windows为例：

1.下载SDK releases

2.将下载的SDK解压到自己的硬盘，并通过命令flutter --version查看版本，eg:

F:Program_Filesflutterin>flutter --version

Flutter 2.6.0-0.0.pre • channel dev • https://github.com/flutter/flutter.git

Framework • revision 83b9e99cfb (3 months ago) • 2021-08-23 19:03:21 +0200

Engine • revision d5adde01dd

Tools • Dart 2.15.0 (build 2.15.0-42.0.dev)

3.环境变量配置，这里已window10为例，右键点击我的电脑->属性->高级系统设置->环境变量

  1).新建用户变量

     变量名：FLUTTER_STORAGE_BASE_URL

     变量值：https://storage.flutter-io.cn

  2).编辑环境变量path中添加新配置： eg:F:Program_Filesflutterin

  3).通过命令flutter doctor，查看是否配置成功

C:Users17990>flutter  doctor
