  1. @override
List<CharacterAnimation> getAnimations(
  1. double progress,
  2. int charCount
)
override

Generates per-character background color sweeps.

Implementation

@override
List<CharacterAnimation> getAnimations(double progress, int charCount) {
  if (charCount == 0) return [];

  return List.generate(charCount, (index) {
    final staggered = staggeredProgress(progress, index, charCount);
    final curved = applyCurve(staggered);
    final returnT = sin(curved * pi);
    final bgOpacity = opacityFrom + (opacityTo - opacityFrom) * returnT;
    return CharacterAnimation(
      backgroundColor: bgOpacity > 0.001
          ? highlightColor.withValues(alpha: bgOpacity.clamp(0.0, 1.0))
          : null,
    );
  });
}
