bool shrinkWrap
final

Whether the extent of the scroll view in the scrollDirection should be determined by the contents being viewed.

If the scroll view does not shrink wrap, then the scroll view will expand to the maximum allowed size in the scrollDirection. If the scroll view has unbounded constraints in the scrollDirection, then shrinkWrap must be true.

Shrink wrapping the content of the scroll view is significantly more expensive than expanding to the maximum allowed size because the content can expand and contract during scrolling, which means the size of the scroll view needs to be recomputed whenever the scroll position changes.

Defaults to false.
