1、设置 Android Studio

检查是否勾选了 Android SDK Tools（Obsolete）

2、java jdk 版本改为 1.8

根据自己的java jdk 8 路径更改环境变量

C:\Program Files\Java\jdk1.8.0_291\bin

3、打开命令行运行 flutter doctor

提示变成下面的样子

    X Android licenses not accepted.  To resolve this, run: flutter doctor --android-licenses

然后运行 flutter doctor --android-licenses 一路 输入y 完成
