Exception thrown regarding unimplemented `unity#createPlayer` method on iOS

[behnamsattar]

Describe the bug
Upon calling the .create() method on the controller, I always get an exception saying it's not implemented. It seems to work, though.

To Reproduce
Here is my code to perform an unload and then recreate.

bool _isCheckingLoadState = false;

Future<void> _reloadUnityScene() async {
    await _unityWidgetController?.unload();
    timer = Timer.periodic(
      const Duration(milliseconds: 500),
      (_) async {
        if (!_isCheckingLoadState) {
          _isCheckingLoadState = true;
          final isLoaded = await _unityWidgetController?.isLoaded() ?? false;
          if (!isLoaded) {
            timer?.cancel();
            await _unityWidgetController?.create();
          }
          _isCheckingLoadState = false;
        }
      },
    );
  }

Expected behavior
The method call should not throw the unimplemented error, as this method is supposed to be working on iOS builds.

Unity (please complete the following information):

• OS: macOS
• Version: 12.6

Smartphone (please complete the following information):

• Device: iPhone 11
• OS: iOS
• Version: 16.1

Additional context

Just playing around with unload on iOS, it looks like nearly anything will recreate the UnityWidget.
Sending a message, calling resume and more all seem to instantly recreate the unity instance.

On Android I only get Unity back after calling create, or showing a new UnityWidget.
