graphicsOverlays property
A collection of GraphicsOverlay objects used to display graphics on top
of the view's content.
To display graphics in the GeoViewController, add the graphics to a
GraphicsOverlay and add the GraphicsOverlay to this collection. The
order of the GraphicsOverlay objects in the collection reflects their
display order in the view. The first GraphicsOverlay in the collection
is drawn beneath all other graphic overlays.
This collection may be empty but is never null. You can't add duplicate
GraphicsOverlay objects to the collection or use this graphics overlay
collection in another GeoViewController.
Use methods such as GeoViewController.identifyGraphicsOverlays, to identify graphics in this collection.
Implementation
List<GraphicsOverlay> get graphicsOverlays => _graphicsOverlays.value;
