private const val FLUTTER_ENGINE_NAME1 = "custom1"

class MainActivity : FlutterActivity()  {

    private val channelName = "com.example.host/start" // 메소드 채널 이름(모듈과 같아야 함)
    private var channel1 : MethodChannel? = null
    private lateinit var binding: ActivityMainBinding

    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)

        flutterEngine.navigationChannel.setInitialRoute("start")
        flutterEngine.dartExecutor.executeDartEntrypoint(
            DartExecutor.DartEntrypoint.createDefault()
        )

        // FlutterEngine을 등록하기 위해 Dart 코드 실행

        channel1 = MethodChannel(flutterEngine.dartExecutor.binaryMessenger, channelName)
        // 메소드채널 위치 설정

        FlutterEngineCache
            .getInstance()
            .put(FLUTTER_ENGINE_NAME1, flutterEngine)
        GeneratedPluginRegistrant.registerWith(flutterEngine);
        channel1?.invokeMethod("param", "{" +
               
                "}")

    }

    override fun onCreate(savedInstanceState: Bundle?) {
