App Crashes when we use flyTo. It sporadic but consistently crashes after using a few times

Nessuno ha ancora preso questa issue.

Users search locations and using the lat and long and we drop the pin for the location. This is the piece of code that does this. the flyTo crashes sometimes but if we just use setCamera it works. Is this a know issue? Have attached the stacktrace below as well.

```
Future _goToCurrentLocation(Position userPosition) async {
try {
final cameraOptions = CameraOptions(center: Point(coordinates: userPosition), zoom: 14.0,);
final animationOptions = MapAnimationOptions(duration: 2000, startDelay: 0,);
//fly to or ease to crashes. So we are using set camera
await _mapboxMap.flyTo(cameraOptions, animationOptions);
//await _mapboxMap.setCamera(cameraOptions);

if (_currentLocMarker != null) {
await _pointAnnotationManager.delete(_currentLocMarker!);
}
// Add a marker at current location
final annotationOptions = PointAnnotationOptions(
geometry: Point(coordinates: userPosition),
iconImage: personalMarkerPin,
iconSize: 1.0,);
_currentLocMarker = await _pointAnnotationManager.create(annotationOptions);
if (!mounted) {
return;
}
await context.read().getCompleteCurrentLocationMetaInfo(
latitude: double.parse(userPosition.lat.toString()),
longitude: double.parse(userPosition.lng.toString()));
}catch(err){
if (kDebugMode) {
print('----errror $err');
}
}

}

```

```

Inizia da _goToCurrentLocation e riproduci chiamate ripetute a flyTo usando le coordinate fornite, confrontando i percorsi flyTo e setCamera. Usa l’errore del canale di AnimationManager e l’assertion di disposal di NavigatorState riportati per isolare il problema; il lavoro è completato quando le chiamate ripetute a flyTo non causano più il crash segnalato.

Scritto dal modello di indicizzazione a partire dal testo della issue.
