Execution failed for task ‘:app:compileflutterbuilddebug’.

The error message “execution failed for task ‘:app:compileflutterbuilddebug'” occurs when there is an issue during the compilation process of a Flutter project’s debug build.

There can be several reasons for this error, and here are a few possible scenarios and their solutions:

1. Missing dependencies or outdated Flutter version: Make sure that you have all the necessary dependencies mentioned in your project’s pubspec.yaml file. Additionally, check if you are using the latest stable version of Flutter. You can run the following command to upgrade Flutter:
   
flutter upgrade

2. Build cache corruption: Sometimes, the build cache can get corrupted, leading to compilation errors. In such cases, you can try clearing the build cache by running the following command:
   
flutter clean

   Then, recompile your project using the regular build command:
   
flutter build debug

3. Conflicting dependencies: If there are conflicting dependencies in your project, it can cause compilation failures. One approach to resolve this issue is to run the dependency solver command:
   
flutter pub get --verbose

   This command will display detailed information about the dependencies and any conflicts. You can then manually update the conflicting dependencies in your pubspec.yaml file and run the above command again.

Apart from these common scenarios, there can be other specific issues related to your project configuration, environment, or Flutter installation. It would be helpful to provide any additional error messages or logs to diagnose the problem more accurately.
