The fill color of all the MapPolygon.

For setting color for each MapPolygon, please check the MapPolygon.color property.

 @override

     MapLatLng(41.8780, -93.0977),
   ];

   _mapSource = MapShapeSource.asset(
     'assets/usa.json',
     shapeDataField: 'name',
   );

   _zoomPanBehavior = MapZoomPanBehavior();
   super.initState();
 }

 @override
