Flutter Plugin not reaching onActivityResult within plugin and reaches with result to MainActivity

[Muthaiah Thiagarajan]

Need some help on plugin development with flutter on Android. Facing the following issue.

class MyPlugin : MethodCallHandler, PluginRegistry.ActivityResultListener{

    override fun onActivityResult(requestCode: Int, p1: Int, data: Intent?): Boolean {

   Doesnt reach here - Actually it should reach here as i have registered on the constructor of this plugin

    }

constructor(registrar: Registrar) {
    this.registrar = registrar
    registrar.addActivityResultListener(this)

}

companion object {
    @JvmStatic
    fun registerWith(registrar: Registrar) {
        val channel = MethodChannel(registrar.messenger(), "my_plugin")
        val plugin = MyPlugin(registrar)
        channel.setMethodCallHandler(plugin)
    }
}

}

class MainActivity: FlutterActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    GeneratedPluginRegistrant.registerWith(this)

  }
  
  override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

   Reaches here
  }
}

I added the override on the MainActivity to find the problem, not intended to have that override method.

You can adds a callback allowing the plugin to take part in handling incoming calls to Activity.onActivityResult(int, int, Intent) by using this method Registrar#addActivityResultListener. I have implemented it in my flutter package here https://github.com/alann-maulana/flutter_beacon/blob/master/android/src/main/java/com/flutterbeacon/FlutterBeaconPlugin.java#L71
