void attach(ScrollPosition position) {
  assert(
    position is MultiDateScrollPosition,
    'MultiDateScrollControllers can only be used with '
    'MultiDateScrollPositions.',
  );
  final linkedPosition = position as MultiDateScrollPosition;
  assert(
    linkedPosition.controller == controller,
    'MultiDateScrollPosition cannot change controllers once created.',
  );
  super.attach(position);
