MatrixRainEffect class

Characters fall vertically with varying brightness like Matrix rain.

Each character drops at a slightly different rate with brightness, blur, and opacity variation, emulating the iconic green rain effect.

MatrixRainEffect({Duration duration = const Duration(milliseconds: 2000), Curve curve = Curves.linear, Color matrixGreen = Colors.green, double fallSpeed = 1.0, double blurSigma = 2.0, Duration delayBetweenChars = Duration.zero}): Creates a Matrix-style rain animation.

blurSigma → double: Gaussian blur applied to characters in motion.
final
curve → Curve: Curve applied to the animation timing for easing.

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
fallSpeed → double: Overall fall speed multiplier (1.0 = default speed).

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 falling animation with brightness fade.
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.
