setDidUnderflow method

void setDidUnderflow (bool value)

Called during layout to indicate whether this object provided insufficient children for the RenderSliverMultiBoxAdaptor to fill the SliverConstraints.remainingPaintExtent.

Typically called unconditionally at the start of layout with false and then later called with true when the RenderSliverMultiBoxAdaptor fails to create a child required to fill the SliverConstraints.remainingPaintExtent.

Useful for subclasses to determine whether newly added children could affect the visible contents of the RenderSliverMultiBoxAdaptor.
