[BUG] Scrolling by apple pencil doesn't work well

[zekunlou]

用apple pencil在树洞区域翻页时，页面滚动延迟，见下

1. 点开一个树洞的帖子
2. 尝试用apple pencil滚动页面（pencil不断向一个方向滑动） 2.1. 发现applepencil先留下一段笔迹，约1s后笔记消失，页面开始跟随笔滚动
3. 或许页面应该直接跟着笔滚动

系统为ipadOS15.2.1 danxi版本为1.3.5 build 151 下面是录屏视频 https://user-images.githubusercontent.com/53600622/154184768-d0714a04-887c-4395-b6d8-c9ff9639d97e.mp4

可以复现，但初步判定为上游框架问题，我们未必能修复。

Upstream issue is here: https://github.com/flutter/flutter/issues/101016. We will keep an eye for a fix.

Maybe it will be updated to the stable channel in the next few versions

I think the easiest and fastest way is to modify the source code by yourself, and follow this modification https://github.com/flutter/flutter/pull/101087

Thanks for informing! Hope it not be so long before the patch comes into beta or dev channel.

Upstream has fixed it in the most recent version of Flutter. Close it.
