【问题描述】：

最近我将我的项目迁移到一个新系统并纠正了所有错误，但我遇到了一个异常，说提供颤振源目录。我添加了颤振SDK路径并检查但我仍然无法解决问题。

FAILURE: Build failed with an exception.

* Where:
Script 'C:\src\flutterSDK\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 572

* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
   > Could not create task ':app:compileFlutterBuildDebug'.
      > Must provide Flutter source directory

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

我已经运行了 Flutter Doctor cmd，一切都很好
