ScrambleEffect class
Characters randomly scramble and unscramble into the final text.
Each character shows a random symbol until its reveal time, which is determined by deterministic noise. The result is a sci-fi/hacker-style decryption effect.

Constructors
- ScrambleEffect({Duration duration = const Duration(milliseconds: 2000), Curve curve = Curves.easeOut, Duration delayBetweenChars = const Duration(milliseconds: 30), int seed = 42, String charset = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'})
-
Creates a scramble/unscramble animation.

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 random char override until noise-based reveal.
override
-
getTotalDuration(
int charCount) → Duration -
Returns the total duration needed to animate all
charCountcharacters.inherited -
noise(
int index, [int offset = 0]) → double -
Returns a deterministic pseudo-random value (0.0–1.0) for the given
indexand optionaloffset.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.
