SliverStickyHeaderBuilder class

A widget that builds a SliverStickyHeader and calls a SliverStickyHeaderWidgetBuilder when the header scroll percentage changes.

This is useful if you want to change the header layout when it starts to scroll off the viewport. You cannot change the main axis extent of the header in this builder otherwise it could result in strange behavior.
