ShakeEffect class

Applies an earthquake-style shake to all characters.

Characters jitter randomly with decreasing intensity. Uses deterministic noise so the shake pattern is repeatable.

Methods

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 noise-based jitter with rotation.
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.
inherited
toString() → String
A string representation of this object.
