Implementation

@override
bool jumpTo(int offset) {
  final before = _offset;
  final next = offset.clamp(0, maxOffset);
  if (next == _offset) {
    _traceScroll(
      'widget_scroll.jumpTo noop '
      'target=$offset offset=$before max=$maxOffset',
    );
    return false;
  }
  _offset = next;
  _notifyListeners();
  _traceScroll(
    'widget_scroll.jumpTo '
    'target=$offset from=$before to=$_offset max=$maxOffset',
  );
  return true;
}
