FireEffect class

Simulates flickering flames on each character.

Characters flicker with random orange/red/yellow colors, scale, jitter, and blur using deterministic noise for a fire-like appearance.

FireEffect({Duration duration = const Duration(milliseconds: 1500), Curve curve = Curves.linear, double jitter = 3.0, double blurSigma = 4.0, double maxScale = 1.15, Duration delayBetweenChars = Duration.zero}): Creates a fire simulation animation.

blurSigma → double: Gaussian blur applied to the flame effect.

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

delayBetweenChars → Duration: Delay between each successive character's animation start.

duration → Duration: Total duration of one full animation cycle for a single character.

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 fire flicker with noise-based color and jitter.
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.
