Map Events

info

The features described on this site have been added in version 0.1.1.

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 Scaffold(
    appBar: AppBar(title: const Text('Events')),
    body: MapLibreMap(
      options: MapOptions(center: Position(9.17, 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
  }
}
