StickyHeaderBuilder class

Sticky Header Builder Widget.

The same as StickyHeader but instead of supplying a Header view, you supply a builder that constructs the header with the appropriate stickyness.

Place this widget inside a ListView, GridView, CustomScrollView, SingleChildScrollView or similar.
