error importing flutter_test / test_api packages

问题

I'm stocked in a problem related to test_api package.
当我运行我的Flutter应用程序时，我遇到了以下错误。

  1. /Applications/flutter/packages/flutter_test/lib/src/_goldens_io.dart:12:8: Error: Error when reading '../../../.pub-cache/hosted/pub.dev/test_api-0.6.1/lib/expect.dart': No such file or directory

<!-- end snippet -->

so that means it doesn't found flutter_test packages as I understand.

I have tried to delete pubspec.lock, flutter clean and pub get,
I have tried flutter pub cache repair and flutter pub cache clean.
I have tried to delete the folder located in .pub-cache/hosted/pub.dev but nothing works. always the same error

Could you please help me with to fix this problem?

Thanks in advance
