I'm trying to run the application in the android emulator but this error keeps popping.

    FAILURE: Build failed with an exception.

* Where:
Script 'C:\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 1005

I have tried the following with no help.

flutter upgrade --force
flutter pub cache repair
flutter clean

Answer 1

Try this:

1. Close project.
2. Go to project repository folder.
3. Delete all generated files, for example:
   • .dart_tool
   • .idea
   • .build
   • .flutter-plugins
   • .flutter-plugins-dependencies
   • .metadata
   • .packages

Nothing should changed in your git changes due to .gitignore file

4. Open Android Studio again

5. Go to File->Invalidate Caches/Restart, then invalidate caches and restart

   if your project structure is corrupted go to: File -> Close Project, close project and reopen it, it should be back to normal.

6. Run all the necessary scripts starting with:

   flutter pub get

   dart pub get

For me the thing was to delete android/app/build folder and run flutter clean.
