ShimmerEffect class

Sweeps a bright highlight band across the text.

Characters transition from baseColor to highlightColor as the band passes, creating a metallic shimmer or loading effect.

getAnimations(double progress, int charCount) → List<CharacterAnimation>
Generates per-character color lerp from highlight band position.
override
getTotalDuration(int charCount) → Duration
Returns the total duration needed to animate all charCount characters.
override
noise(int index, [int offset = 0]) → double
Returns a deterministic pseudo-random value (0.0–1.0) for the given index and optional offset.
inherited
