FlagWaveEffect class

Characters undulate in a 3D wave like a waving flag.

Uses CharacterAnimation.rotationY in a sinusoidal pattern that travels across the text, creating a perspective depth effect similar to a fluttering banner.

Constructors

FlagWaveEffect({Duration duration = const Duration(milliseconds: 1500), Curve curve = Curves.easeInOut, double amplitude = 0.4, int waveCount = 2, Duration delayBetweenChars = Duration.zero})
Creates a flag-waving 3D rotation effect.

delayBetweenChars → Duration
Delay between each successive character's animation start.
finalinherited
duration → Duration
Total duration of one full animation cycle for a single character.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.

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 rotationY following a traveling sine wave.
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.
