5、安装过程当中碰到的问题

    1.Android license status unknown.

      首先 运行 flutter doctor --android-licenses，若是提示

A newer version of the Android SDK is required. To update, run:
D:\software\android-sdk-windows\tools\bin\sdkmanager --update

     则运行 D:\software\android-sdk-windows\tools\bin\sdkmanager --update ,若是提示

Warning: An error occurred during installation: Failed to move away or delete existing target file: D:\software\android-sdk-windows\tools
Move it away manually and try again..
done

    解决方法：进入 D:\software\android-sdk-windows 目录，把tools文件夹改成tool，再运行 D:\software\android-sdk-windows\tool\bin\sdkmanager --update

   运行完成后会从新建立tools文件夹，把tools文件夹下的全部文件复制到tool文件夹后把文件夹名称改成tools.

   再运行  flutter doctor --android-licenses
