hasScrollBody property
Indicates whether the child has a scrollable body, this value cannot be null.
Defaults to true such that the child will extend beyond the viewport and scroll, as seen in NestedScrollView.
Setting this value to false will allow the child to fill the remainder of
the viewport and not extend further. However, if the
SliverConstraints.precedingScrollExtent and/or the child's
extent exceeds the size of the viewport, the sliver will defer to the
child's size rather than overriding it.
Implementation
final bool hasScrollBody;
