GlassScrollEdgeStyle enum

Edge effect style matching iOS 26's .scrollEdgeEffectStyle.

Controls how scroll content fades or frosts at the edges when it meets a glass surface (navigation bar, bottom bar, etc.).

Values

blur → const GlassScrollEdgeStyle

A progressive, graduated blur that frosts live content under the bar.

Uses ProgressiveBlur to blur live scrolling content with a gradient sigma so high frequencies (text, sharp edges) melt into a soft frost, maintaining contrast and legibility for bar chrome while keeping content visible underneath.

This is an opt-in design enhancement beyond the system default, ideal for rich media grids, video feeds, or custom dynamic gradients.

Compositing cost: Internally uses a BackdropFilterLayer, which requires compositing on every frame the widget is visible. On Metal/Impeller this is GPU-only and cheap; on Skia/Android it carries a slightly higher overhead than soft or hard. On pages that use no other glass surfaces, soft remains a lighter alternative.

soft → const GlassScrollEdgeStyle

A rounded, diffused fade — content dissolves into the backdrop.

Matches iOS 26's .scrollEdgeEffectStyle(.soft). This is the default and recommended style for standard navigation and list views. When inside a GlassPage (or with texture capture enabled), paints a slice of the background texture; outside, falls back to a solid gradient.

hard → const GlassScrollEdgeStyle

A crisp boundary — content has a sharper cutoff at the bar edge.

Matches iOS 26's .scrollEdgeEffectStyle(.hard). Uses a 50% tighter transition zone with a steep opacity curve, ideal for dense settings lists, tabular data, and utility screens.
