W: Scrollable + Widget,{ /* private fields */ }
Expand description
Scroll bar controls
This is a wrapper adding scroll bar controls around a child. Note that this
widget does not enable scrolling; see ScrollBarRegion
for that.
Scroll bar positioning does not respect the inner widget’s margins, since
the result looks poor when content is scrolled. Instead the content should
force internal margins by wrapping contents with a (zero-sized) frame.
ScrollRegion
already does this.

By default scroll bars are automatically enabled based on requirements.
Use the HasScrollBars
trait to adjust this behaviour.
