当EasyRefresh里面存在其他含ScrollController的widget时，其他Controller调用animateTo会导致EasyRefresh的IndicatorMode状态重置

[gdmec07120836]

先看效果 https://github.com/xuelongqy/flutter_easy_refresh/assets/6902443/edccc6c3-fa6e-48dd-b3ff-337b50a5bcdf

可以看到黄色的tab切换之后下拉刷新CupertinoHeader消失了，调试发现是_offset:0.0，IndicatorMode的状态变成了IndicatorMode.inactive 再进一步调试发现是Swiper开了自动切换，里面的TransformerPageController调用了animateTo，导致EasyRefresh的ScrollPhysics也被回调了，重新检测了滑动边界。 关键代码： Swiper切换Ui的时候这里的短点也会执行

大佬可以去试一下。 easy_refresh: 3.4.0 card_swiper: 3.0.1 用其他Controller应该也是这个效果，我懒得重新写就直接用这个widget了
