原生于 Flutter 数据交换：Flutter 似乎没有从 MethodChannel 接收数据

问：

我正在构建一个播放视频的应用程序，我可以从 Flutter 打开数据（链接视频）并将其传递给 Native，但我需要在 VideoActivity 末尾传递播放器的位置

其实我有这个代码

主要活动

class MainActivity: FlutterActivity() {
    private val CHANNEL = "ankit.flutter.dev/video"

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        GeneratedPluginRegister.registerGeneratedPlugins(FlutterEngine(this))
        flutterEngine?.dartExecutor?.let {
            MethodChannel(it, CHANNEL).setMethodCallHandler { call, result ->
                if (call.method == "playVideo") {
                    goToVideoActivity()
                    result.success(null)
                } else if (call.method == "updateVideoPosition") {
                    val position = call.arguments as Int
                    result.success(position)
                }
            }
        }

    }

视频活动

private lateinit var flutterEngine: FlutterEngine

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = VideoLayoutBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)

        // Inizializza il FlutterEngine all'avvio dell'app
        flutterEngine = FlutterEngine(this)
        flutterEngine.dartExecutor.executeDartEntrypoint(DartExecutor.DartEntrypoint.createDefault())
        FlutterEngineCache.getInstance().put("1", flutterEngine)
}

    override fun onDestroy() {
        super.onDestroy()
        releasePlayer()
        val methodChannel = MethodChannel(flutterEngine.dartExecutor.binaryMessenger, "ankit.flutter.dev/video")
        Log.d("posizione 1", "$currentPosition")
        methodChannel.invokeMethod("updateVideoPosition", currentPosition)
    }

$currentPosition使用正在工作的另一部分代码正确更新（末尾的日志显示正确的值）

在颤振方面，我有这个

  @override
  void initState() {
    super.initState();
    MethodChannel platform = MethodChannel("ankit.flutter.dev/video");
    platform.setMethodCallHandler((call) async {
      print("Metodo ricevuto: ${call.method} argomenti: ${call.arguments}");
      if (call.method == 'updateVideoPosition') {
        final position = call.arguments as int;
        print('Current video position: $position milliseconds');
      }
    });
  }

Flutter 似乎没有从原生活动中获得任何价值，我无法弄清楚原因（我不擅长 kotlin，我正在使用许多教程/GPT 来弄清楚我需要什么

谢谢大家的帮助
