Target kernel_snapshot failed: Exception


FAILURE: Build failed with an exception.

* Where:

* What went wrong:
Execution failed for task ':app:compileFlutterBuildRecDebug'.
> Process 'command '/Applications/flutter/bin/flutter'' finished with non-zero exit value 1

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
