In Xamarin I am trying:
GraphicCollection Graphics = new GraphicCollection();
it does not work -> does not take 0 arguments
what I want to do is to rewrite the PointClusterer sample for the windows desktop into Xamarin Forms
It isn't creatable or settable on the overlay.
Instead create a GraphicsOverlay. It comes with a GraphicsCollection in it that you can use. To put if another way: Think of your overlay as the graphics collection.
okay, I understand, like:
GraphicsOverlay overlay = new GraphicsOverlay();
GraphicCollection collection = overlay.Graphics;
