Implementation

@override
void initState() {
  super.initState();

  mapBloc = BlocProvider.of<MapBloc>(context);
  mapBloc.add(MapInitEvent());
  const pollRefreshDelay = const Duration(seconds: 3); // update every 3 sec
  new Timer.periodic(
      pollRefreshDelay,
      (Timer t) => BlocProvider.of<MapBloc>(context)
          .add(MapUpdateEvent(zoomLevel: currentZoom)));
}
