LiquidGlassScope class

A scope that provides infrastructure for glass refraction on Skia and Web.

Place LiquidGlassScope at the root of a stack or page. Descendant GlassEffect widgets (used by GlassSegmentedControl, GlassTabBar) will automatically find and sample the capture surface marked by GlassBackgroundSource.

On Impeller, LiquidGlassScope is not needed — GlassQuality.premium uses the native scene graph for refraction.

Usage:

LiquidGlassScope(
  child: Stack(
    children: [
      // 1. Mark the capture surface
      GlassBackgroundSource(
        child: Image.asset('wallpaper.jpg'),
      ),

      // 2. Glass widgets sample it automatically
      Center(child: GlassSegmentedControl(...)),
    ],
  ),
)
