NestedScrollViewHeaderSliversBuilder typedef

NestedScrollViewHeaderSliversBuilder = List<Widget> Function(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);
