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);}

Answer 1

I updated all my project packages. That solved the issue for me.

Answer 2

You need to equalize kotlin version in first row which is ext.kotlin_version = '1.6.10' to according to classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" of underlined $kotlin_version

After this, problem will solve...

Answer 3

I'm also faced same issue, I done with below changes. But it's a temporary bug fix. For more reference

Search for the FlutterLocationService.kt and edit it change override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>?, grantResults: IntArray?): Boolean to

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray): Boolean
