contentAwareBrightness property

Whether to install a GlassContentAwareScope around the scaffold's body and bars.

When true, the scaffold wraps the body in GlassContentAwareContent and the entire Stack in GlassContentAwareScope. This enables bars with adaptiveBrightness: true to sample the body content and automatically flip between light and dark appearance.

The standalone GlassContentAwareScope and GlassContentAwareContent widgets remain available for custom layouts that don't use GlassScaffold.

GlassScaffold(
  contentAwareBrightness: true,
  bottomBar: GlassBottomBar(
    adaptiveBrightness: true,
    ...
  ),
  body: CustomScrollView(...),
)
