children property
Widgets to be placed onto the map in a Stack-like fashion
Widgets that use MobileLayerTransformer will be 'mobile', will move and rotate with the map. Other widgets will be 'static' (and should usually use Align or another method to position themselves). Widgets/layers may or may not identify which type they are in their documentation, but it should be relatively self-explanatory from their purpose.
Implementation
final List<Widget> children;
