I Found the answer and it worked for me. Here it is just replace your code with following code in MainActivity.kt file.

package //your package name for eg.com.example.filename

import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant

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