set method
Set an existing anntotation to the map. Use this to do a fast update for a single annotation
Implementation
Future<void> set(T anntotation) async {
assert(_idToAnnotation.containsKey(anntotation.id),
"you can only set existing annotations");
_idToAnnotation[anntotation.id] = anntotation;
final oldLayerIndex = _idToLayerIndex[anntotation.id];
final layerIndex = selectLayer != null ? selectLayer!(anntotation) : 0;
if (oldLayerIndex != layerIndex) {
// if the annotation has to be moved to another layer/source we have to
// set all
await _setAll();
} else {
await controller.setGeoJsonFeature(
_makeLayerId(layerIndex), anntotation.toGeoJson());
}
}
