NestedScrollViewHeaderSliversBuilder typedef

List<Widget> NestedScrollViewHeaderSliversBuilder (BuildContext context, bool innerBoxIsScrolled)

Signature used by NestedScrollView for building its header.

The innerBoxIsScrolled argument is typically used to control the SliverAppBar.forceElevated property to ensure that the app bar shows a shadow, since it would otherwise not necessarily be aware that it had content ostensibly below it.

Implementation

typedef NestedScrollViewHeaderSliversBuilder = List<Widget> Function(BuildContext context, bool innerBoxIsScrolled);
