======== Exception caught by foundation library ====================================================
The following assertion was thrown while dispatching notifications for ScrollController:
ScrollController attached to multiple scroll views.
'package:flutter/src/widgets/scroll_controller.dart':
Failed assertion: line 109 pos 12: '_positions.length == 1'

这个问题 我在MAC 在scrollbar 滚动时候触发。

问题重现

1. 选择 webchat tab（基本任何一个tab 也会发生）
2. 手势滚动 两次

这是我的flutter doctor 信息
