+/// This widget is useful when you have a single box that will normally be
+/// entirely visible, for example a clock face in a time picker, but you need to
+/// make sure it can be scrolled if the container gets too small in one axis
+/// (the scroll direction).
+///
+/// It is also useful if you need to shrink-wrap in both axes (the main
+/// scrolling direction as well as the cross axis), as one might see in a dialog
+/// or pop-up menu. In that case, you might pair the [SingleChildScrollView]
+/// with a [BlockBody] child.
+///
+/// When you have a list of children and do not require cross-axis
+/// shrink-wrapping behavior, for example a scrolling list that is always the
