          //   onPressed: () async {
          //     if (await _unityWidgetController.isReady() ?? false) {
          //       _unityWidgetController.unload();
          //       _unityWidgetController.dispose();
          //     }

      body: UnityWidget(
        onUnityCreated: _onUnityCreated,
        onUnityMessage: onUnityMessage,
        onUnitySceneLoaded: onUnitySceneLoaded,
        useAndroidViewSurface: true,
        fullscreen: false,

  }

  void onUnityMessage(message) {
    print('Received message from unity: ${message.toString()}');
  }

  void onUnitySceneLoaded(SceneLoaded? scene) {
    if (scene != null) {
      print('Received scene loaded from unity: ${scene.name}');
      print('Received scene loaded from unity buildIndex: ${scene.buildIndex}');
    } else {
      print('Received scene loaded from unity: null');
    }
  }

  // Callback that connects the created controller to the unity controller
  void _onUnityCreated(UnityWidgetController controller) async {
    _unityWidgetController = controller;
    await Future.delayed(const Duration(milliseconds: 2000));
    await _unityWidgetController.resume();
  }

// void _onUnityCreated(controller) async {
