Gradle task assembleRelease failed with exit code 1

Solution:

Something that work for me is: Delete your pubspec.lock, and press ‘Pub Get’ in your pubspec.yaml, it’ll regenerate pubspec.lock file again and should fix the problem.

Go to pubspec.yaml file, try doing Packages get | Pub get, and then build the project again.

I faced the same error and further, I tried:

flutter clean
flutter pub get in the terminal, and the issue was solved!
