- if turning Hide Navigation Bar on and Render outside safe area on, the bar doesn't show up.

Notes

can't quit Unity process on this library, but can unload based on the flollowing.
- https://github.com/juicycleff/flutter-unity-view-widget/issues/447
- Start() is called even after reloading
can override custom loading screen on unity loading screen like the following.

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(fit: StackFit.expand, children: <Widget>[
        UnityWidget(
          onUnityCreated: _onUnityCreated,
          onUnityMessage: _onUnityMessage,
        ),
        if (_showLoading)
          Container(
              color: Colors.white,
              child: Center(
                child: LoadingAnimationWidget.threeRotatingDots(
                  color: Colors.blue,
                  size: 50,
                ),
              )),
      ]),
    );
  }

  void _onUnityMessage(message) async {
    logger.i('Received message from unity: ${message.toString()}');

    String msgStr = message.toString();
    if (msgStr == 'CompleteToLoad') {
      await Future.delayed(const Duration(seconds: 1));
      setState(() {
        _showLoading = false;
      });
    }
  }
