flutter_map_supercluster

Description:

flutter map supercluster

Flutter Map Supercluster (previously flutter_map_fast_cluster) #
Two different Marker clustering layers for flutter_map:

SuperclusterImmutableLayer: An extremely fast Marker clustering layer, Markers may not be
added/removed.
SuperclusterMutableLayer: An slightly slower (but still very fast) Marker clustering layer.
Markers can be added/removed.

If you want beautiful clustering animations check out flutter_map_marker_plugin. It will perform
well for quite a lot of Markers on most devices. If you are running in to performance issues and are
happy to sacrifice animations then this package may be for you.

urlTemplate: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
subdomains: ['a', 'b', 'c'],
),
),
SuperclusterLayer.immutable(
initialMarkers: markers, // Provide your own
clusterWidgetSize: const Size(40, 40),
builder: (context, markerCount, extraClusterData) {
return Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20.0),
color: Colors.blue,
),
child: Center(
child: Text(
markerCount.toString(),
style: const TextStyle(color: Colors.white),
),
),
);
},
),
],
);

cluster layers.
