RainbowEffect class

Cycles rainbow HSL colors across characters over time.

Each character gets a distinct hue offset, creating a multicolored sweep that rotates through the color wheel.

RainbowEffect({Duration duration = const Duration(milliseconds: 2000), Curve curve = Curves.linear, double saturation = 0.8, double lightness = 0.6, int cycleCount = 1, Duration delayBetweenChars = Duration.zero}): Creates a rainbow color cycling animation.

curve → Curve: Curve applied to the animation timing for easing.

cycleCount → int: Number of full color cycles during one animation.
final
delayBetweenChars → Duration: Delay between each successive character's animation start.
finalinherited
duration → Duration: Total duration of one full animation cycle for a single character.

hashCode → int: The hash code for this object.
no setterinherited
lightness → double: HSL lightness of the colors (0.0–1.0).
final
runtimeType → Type: A representation of the runtime type of the object.

saturation → double: HSL saturation of the colors (0.0–1.0).
final

applyCurve(double t) → double: Applies the effect's curve to a linear value t (0.0–1.0).
inherited
getAnimations(double progress, int charCount) → List<CharacterAnimation>: Generates per-character hue-shifted colors across the rainbow.
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
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
staggeredProgress(double globalProgress, int index, int charCount) → double: Computes the per-character progress for staggered animations.
