3 years ago How many markers do you have on average when your app crashes ?
I think you may not be using the library correctly, the updateMarkers method is therefore called too many times, causing the application to crash.

3 years ago The app was crashing when there were about 500-600 markers. Anyway, I think the issue was calling updateMarkers too many times. One more mistake was that updateMarker was called in _onCameraMove. After doing a bit of refactoring, now it is working fine.
As the number of markers increases the map begins to lag and unresponsive. And finally, the app crashes.
/// my map GoogleMap( mapToolbarEnabled: false, zoomControlsEnabled: false, onMapCreated: _onMapCreated, myLocationEnabled: false, myLocationButtonEnabled: false, minMaxZoomPreference: MinMaxZoomPreference(1.0, 14.0), initialCameraPosition: CameraPosition( target: widget.initialPosition, zoom: _defaultZoom, ), markers: _updateMarker( Provider.of(context).userDetailsList),
onCameraMove: _onCameraMove,
onCameraIdle: _onCameraIdle,
),
/// update marker Set _updateMarker(List userDetailsList) {
_manager.setItems(<ClusterItem>[
for (UserDetails userDetails in userDetailsList)
ClusterItem(LatLng(userDetails.lat, userDetails.long),
item: Place(name: userDetails.name))
]);
_manager.updateMap();
return _markers;
}
/// cluster manager ClusterManager _initClusterManager() { return ClusterManager(items, _updateMarkers,
markerBuilder: _markerBuilder, initialZoom: _defaultZoom);
}
List<ClusterItem> items = [];
Not able to figure out what's causing the issue, can it be the package issue or flutter issue? Any help will be appreciated.
