tile The tile to check for data availability Returns true if tile data is available, false otherwise

Implementation

@override
Future<bool> supportsTile(Tile tile) async {
  final List<Datastore> datastoresList = datastores.toList();
  List<Future<bool>> futures = [];
  for (Datastore mdb in datastoresList) {
    futures.add(() {
      if (_datastoreIntersectsTile(mdb, tile)) {
        return mdb.supportsTile(tile);
      }
      return Future.value(false);
    }());
  }
  List<bool> results = await Future.wait(futures);
  for (bool result in results) {
    if (result) {
      return true;
    }
  }
  return false;
}
