centerCurrentLocationStreamController.add(17) zoom doesn't work like before

[bmason8]

After upgrading to v_3.0.0 centering the location marker doesn't work for me like in v_2.0.0. Before it would zoom to the level entered as the parameter in centerCurrentLocationStreamController.add(17);. Now it will center the icon but won't zoom to the correct level. It just zooms in a tiny bit each time I make the call. I'm hoping I'm just doing something wrong but if I am I can't see where.

Here's how I'm setting up the Marker widget:

LocationMarkerLayerWidget(
                  options: LocationMarkerLayerOptions(
                    accuracyCircleColor: Colors.deepPurple.shade100.withOpacity(0.3),
                    headingSectorColor: Colors.deepPurple.shade300.withOpacity(0.8),
                    marker: DefaultLocationMarker(
                      color: (_mapControlNotifier.trackingStatus) ? Colors.deepPurple.shade300 : tmSecondary,
                    ),
                    positionStream: const LocationMarkerDataStreamFactory().geolocatorPositionStream(
                      stream: Geolocator.getPositionStream(
                        locationSettings: const LocationSettings(
                          accuracy: LocationAccuracy.high,
                          distanceFilter: 1,
                        ),
                      ),
                    ),
                  ),
                  plugin: LocationMarkerPlugin(
                    centerCurrentLocationStream: _mapControlNotifier.centerCurrentLocationStreamController.stream,
                    centerOnLocationUpdate: _mapControlNotifier.centerOnLocationUpdate,
                  ),
                ),

I'm also finding that the heading is now off. Moving my phone a couple of degrees will spin the header 360 degrees or more. Any help would be appreciated.

You mentioned two issue.

1) The zooming by sending single to centerCurrentLocationStream stop before it complete. I found that the map stop zooming if the location is updated with CenterOnLocationUpdate.always during the zooming. This may cause this problem. Please try v3.0.1, it should fix this problem.

2) The header is spinning unexpectedly. It is because of the unit of heading (degree and radius) do not match. Sorry about that. This problem also be fixed in v3.0.1.

Have you try the example provided in the repo? Is it work? Can you show me how you build the FlutterMap?
