WidgetPin class abstract

Controller for a Widget pinned at a fixed geographical location on the map.

A pinned Widget tracks the geographical location as the map is being manipulated. It behaves like a MapMarker, only it's a regular Flutter Widget and is not part of normal map rendering.

WidgetPin allows modifying the geographical location of the pinned Widget as well as its placement relative to it.

Use HereMapController.pinWidget to pin (add) a Widget to a map and obtain in instance of WidgetPin that controls it.

To unpin (remove) a Widget from the map, use HereMapController.unpinWidget. or WidgetPin.unpin.
