ScrollArea class

A convenience widget that wraps SingleChildScrollView with optional sizing and an optional Scrollbar.

Provide width and/or height to constrain the scroll area. When showScrollbar is true (the default), a Scrollbar is drawn to the right of the scrollable content.

You may supply an external ScrollController to programmatically control the scroll position or to share it with other widgets.
