I have this errors on my debug console, and not show nothing the camera preview in web mobile, but on my Mac browser works fine

Height of Platform View type: [plugins.flutter.io/camera_2] may not be set. Defaulting to `height: 100%`.
Set `style.height` to any appropriate value to stop this message.
Width of Platform View type: [plugins.flutter.io/camera_2] may not be set. Defaulting to `width: 100%`.
