Many errors when I exit the panorama viewer screen

[dariocavada]

If I open a screen where I have a panorama widget from the home page and then go back to the home page, in the console I have several errors because the gyroscope event continues to be sent by the panorama component ...

A way to solve this issue is to assign this.scene = null in the dispose of the panorama.dart code:

@override
  void dispose() {
    this.scene = null;
    _controller.dispose();
    super.dispose();
  }

With the latest version in this repository this works.
