WiggleEffect class

Applies random jitter and rotation to each character.

Uses deterministic noise so each character has a unique, repeatable wiggle pattern with configurable amplitude, frequency, and rotation.

WiggleEffect({Duration duration = const Duration(milliseconds: 1000), Curve curve = Curves.easeInOut, double amplitude = 4.0, double frequency = 3.0, double rotationAmplitude = 0.05, Duration delayBetweenChars = Duration.zero}): Creates a wiggling jitter effect per character.

applyCurve(double t) → double: Applies the effect's curve to a linear value t (0.0–1.0).

getAnimations(double progress, int charCount) → List<CharacterAnimation>: Generates per-character noise-based jitter with rotation.
override
getTotalDuration(int charCount) → Duration: Returns the total duration needed to animate all charCount characters.

noise(int index, [int offset = 0]) → double: Returns a deterministic pseudo-random value (0.0–1.0) for the given index and optional offset.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
