Flutter Map Radius Cluster

A clustering plugin for flutter_map with async marker/cluster searching within a defined radius.


This plugin is new and the API is subject to change frequently in the near future.


Add flutter_map and flutter_map_radius_cluster to your pubspec:

  flutter_map: any
  flutter_map_radius_cluster: any # or the latest version on Pub

Add it to FlutterMap and configure it using RadiusClusterLayerOptions.

  Widget build(BuildContext context) {
  return FlutterMap(
    options: MapOptions(
      zoom: 5,
      maxZoom: 15,
    children: <Widget>[
        options: TileLayerOptions(
          urlTemplate: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
          subdomains: ['a', 'b', 'c'],
        options: RadiusClusterLayerOptions(
          radiusInKm: 100.0,
          search: (radius, center) {
            /* ... your search implementation here */
          clusterWidgetSize: const Size(40, 40),
          anchor: AnchorPos.align(AnchorAlign.center),
          builder: (context, clusterData) {
            clusterData as ClusterDataWithCount;
            return Container(
              decoration: BoxDecoration(
                  borderRadius: BorderRadius.circular(20.0),
                  color: Colors.blue),
              child: Center(
                child: Text(
                  style: const TextStyle(color: Colors.white),
