GlassHeader

GlassHeader renders a frosted-glass panel that slides in from the top of the scroll view. It uses BackdropFilter to blur the content behind it, producing a modern glassmorphism effect that works especially well on image-heavy backgrounds.

Basic Usage

SmartRefresher(
  controller: _controller,
  header: const GlassHeader(),
  onRefresh: _onRefresh,
  child: ListView.builder(...),
)
