readLabelsSingle method
Reads only labels for tile. Labels are pois as well as ways that carry a name tag. It is permissible for the MapDataStore to return more data. This default implementation returns all map data, which is inefficient, but works.
@param tile tile for which data is requested. @return label data for the tile.
Implementation
@override
Future<DatastoreReadResult?> readLabelsSingle(Tile tile) async {
return readMapDataSingle(tile);
}
