Polygons

addPolygon(String name, List<LatLng> points, double width = 1.0, Color color = const Color(0xFF00FF00), double borderWidth = 0.0, Color borderColor = const Color(0xFFFFFF00)): add a polygon on the map

On ready callback #

Execute some code right after the map is ready:

@override
void initState() {
   statefulMapController.onReady.then((_) {
      setState((_) =>_ready = true);
   });
   super.initState();
}

Changefeed #

A changefeed is available: it's a stream with all state changes from the map controller. Use it to update the map when a change occurs:

statefulMapController.onReady.then((_) {
    statefulMapController.changeFeed.listen((change) => setState(() {}));
   });
}
