AdaptiveLiquidGlassLayer class

An adaptive liquid glass layer that provides a glass background with proper fallback handling across all platforms.

This is a custom replacement for LiquidGlassLayer that uses AdaptiveGlass for rendering, ensuring the background uses the lightweight shader on web/Skia instead of falling back to FakeGlass.

Fallback chain for background:

  • Premium + Impeller → Full shader (best quality) + blending support
  • Premium + Skia/web → Lightweight shader (not FakeGlass!)
  • Standard → Lightweight shader

Blending:

  • blendAmount parameter only works on Impeller (requires full renderer)
  • On Skia, blending is ignored (widgets render separately)
  • This matches chromatic aberration behavior (Impeller-only features)

Usage:

// With explicit settings:
AdaptiveLiquidGlassLayer(
  settings: LiquidGlassSettings(...),
  quality: GlassQuality.premium,
  shape: LiquidRoundedSuperellipse(borderRadius: 32),
  blendAmount: 10.0, // Impeller-only
  child: YourContent(),
)

// Or use theme (recommended):
AdaptiveLiquidGlassLayer(
  child: YourContent(), // Uses GlassTheme settings automatically
)

Blend amount for smooth glass transitions (Impeller-only).
final
child → Widget
The widget to display inside the glass layer.
final
