当我点击 Pub 进入 pubspec.yaml 时，弹出错误：
Oops; flutter has exited unexpectedly: "Invalid argument(s): Cannot find executable for C:\Users\Ali\flutter\bin\cache\dart-sdk\bin\pub.bat.".
A crash report has been written to C:\Users\Ali\AndroidStudioProjects\inheritance_widgeta_context\flutter_17.log.
我已更新所有 SDK 工具
如何解决这个问题？
这是日志：

我通过以下 3 个步骤解决了这个问题，
1-:- 您需要禁用病毒防护，
2-:- 您应该完全删除缓存文件夹（它位于例如：- 'C:\flutter\bin\cache'）
3-：运行“Flutter Doctor”，它会再次下载所有工件
