How to solve flutter.gradle and flutter.bat error?Script 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' && flutter.bat error

Question

FAILURE: Build failed with an exception.

• Where:

Script 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 991

• What went wrong:

Execution failed for task ':app:compileFlutterBuildDebug'.

Process 'command 'C:\src\flutter\bin\flutter.bat'' finished with non-zero exit value 1

Answer 1

The solution that worked for me was:

1. Delete pubspec.lock file
2. Do flutter pub get
3. Run the project

And it worked.

Answer 2

I was able to get around this by running with null safety turned off. See this article for details.

 dart --no-sound-null-safety run
 flutter run --no-sound-null-safety
