Fix PluginApplicationException

✅ Solution

PluginApplicationException in Flutter often arises from outdated or incompatible Gradle versions or dependencies within your Android project, especially when using Add2App or integrating Flutter modules. Ensure your `android/build.gradle` and `android/app/build.gradle` files use compatible Gradle and Android Gradle Plugin versions, and that any Flutter plugin dependencies are up-to-date with the AGP version you are using. Try upgrading Gradle and AGP to the latest stable versions, or downgrading to versions known to be compatible with your Flutter plugins, then invalidate caches and restart.
