CupertinoScrollbar class
An iOS style scrollbar.
A scrollbar indicates which portion of a Scrollable widget is actually visible.
To add a scrollbar to a ScrollView, simply wrap the scroll view widget in a CupertinoScrollbar widget.
By default, the CupertinoScrollbar will be draggable (a feature introduced in iOS 13), it uses the PrimaryScrollController. For multiple scrollbars, or other more complicated situations, see the controller parameter.
