Solution Tried:

1. Invalidate Caches/Restart
2. Build -> Clean Project
3. Updated Kotlin Plugin and used latest Kotlin version
4. Run ./gradlew assembleDebug
5. Run flutter doctor and flutter clean

Previously I tried to build for release and the release build, but some features weren't working. So I looked around and found that I was supposed to add the code below in the main method in the MainActivity.kt in the android section, that's when this issue started. I even tried to comment out the method but the error is still there.

override fun configureFlutterEngine(@NonNull flutterEngine:FlutterEngine){GeneratedPluginRegistrant.registerWith(flutterEngine);}
