New Feature: Add widget(s) on a given position

[rlazom]

Hi, first of all, I really love your plugin men, awesome job 😎🤘

I like to suggest a new feature, I think it could be very useful. Feature: Add widget(s) on a given position.

The idea could be add to the current panorama class a list of objets(a widget with the position in the scene):

Panorama(
  child: Image.asset('assets/panorama.jpg'),
  widgets: <PositionedWidget>[]
),

And the PositionedWidget Class something like:

PositionedWidget {
  Vector3 position,
  Widget widget
}

This could be used to add (for example):

• A button in a position of the image an enable new interactions
• A text/hint when the user click a widget.
• Etc.

It would be great, because it could be used for virtual tours (click to an icon --> moving from one panorama to another) or to display information on a specific point (for example an object in a museum) etc ...

Would be good to have also an example of how to do this (also without changing the plugin)

Some tests I've done:

• Panorama version ^0.1.2 does not have widgets support (just tried, but no new code for widgets)
• Taking the 791473c version and the example in the repository I have some strange errors
• If I use a simple widget like this:

  Hotspot(
  latitude: -76.0,
  longitude: -52.0,
  widget: GestureDetector(
  onTap: () {
    print('tap tap');
  },
  child: Container(
    //padding: EdgeInsets.all(8),
    color: Colors.white,
    child: Icon(Icons.search),
  ),
  ),
  ),

it works (at least on Android):
