This is my MainActivity.kt file:

package com.app.chasescroll_flutter

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity

class MainActivity: FlutterFragmentActivity() {
}

//************************************************

I have also changed my build.gradle/app and changed the kotlin version to 1.5.10 and upgraded my minSdkVersion to 21. I am astuck on this issue from 3 days and couldn't find any helping material from github/issues. Kindly guide me if there's any way to solve this. Thanks

Please continue here: #538

It's possible that the android:name=".MainActivity" part does not point to the correct class
