AntiFlickerDirection enum

Defines the directions for the anti-flicker gradient used with GlassAntiFlicker.

This enum specifies the possible fade directions to prevent visual artifacts at the edges of glass panels in Arcane UI components. It enables smooth transitions between Glass elements and surrounding content, particularly useful in layouts like Section or FillScreen where glass overlays might otherwise cause flickering during animations or scrolling.

Key features:

  • Supports four cardinal directions for flexible edge handling.
  • Integrates seamlessly with ArcaneTheme for consistent styling.
  • Performance: Stateless and const, ensuring no unnecessary rebuilds in dynamic UIs like SliverScreen.

Usage example in a Section:

Section(
  child: GlassAntiFlicker(direction: AntiFlickerDirection.bottom),
)

  • GlassAntiFlicker, the widget that applies this gradient.

Values

top → const AntiFlickerDirection

Gradient fades from top to bottom, ideal for top edges of glass panels.

bottom → const AntiFlickerDirection

Gradient fades from bottom to top, suitable for bottom-aligned Glass in FillScreen.

left → const AntiFlickerDirection

Gradient fades from left to right, for left-side transitions in Section layouts.

Gradient fades from right to left, for right-side anti-flicker in navigation-heavy UIs.
