Events

The event system is the used if you want to listen to any user interactions or state changes on the map.

Basic Usage

To listen to map events, implement a callback function for the onEvent parameter.

@override
Widget build(BuildContext context) {
  return MapLibreMap(
    options: MapOptions(center: Geographic(lon: 9.17, lat: 47.68)),
    onEvent: _onEvent,
  );
}

void _onEvent(event) {
  print(event.runtimeType);

  // check for the event type
  if (event is MapEventClicked) {
    print('The map has been clicked at ${event.point.lng}, ${event.point.lat}');
  }

  // or use a switch statement to listen to all the events you are interested in
  switch (event) {
    case MapEventMapCreated():
      print('map created');
    case MapEventStyleLoaded():
      print('style loaded');
    default:
    // ignore all other events
  }
}
