loadmore时，拉高一点，手不离开屏幕，当前cell会跳动到新数据的最后一条，并且再触发一次loadmore。

解决方案：


class MyScrollPhysics extends BouncingScrollPhysics {
  const MyScrollPhysics({ScrollPhysics parent}) : super(parent: parent);
  @override
  MyScrollPhysics applyTo(ScrollPhysics ancestor) {
    return MyScrollPhysics(parent: buildParent(ancestor));
  }

  @override
  double adjustPositionForNewDimensions({
    ScrollMetrics oldPosition,
    ScrollMetrics newPosition,
    bool isScrolling,
    double velocity,
  }) {
    return newPosition.pixels;
  }
}

SmartRefresher(
physics: MyScrollPhysics()
)

人才啊，有一个 issue 是我提的，一直没解决，最近再关注下（其实早期flutter版本是没问题的）
楼主去官方提得这么详细，这个功能官方确实需要改进，太影响体验了，不知道接受了没有。
感谢楼主提出解决方案。
