BlurEffect class

Transitions characters from blurry to sharp (or vice versa).

Each character starts with a Gaussian blur of sigmaFrom and resolves to sigmaTo, creating a focus-in effect.

Constructors

BlurEffect({Duration duration = const Duration(milliseconds: 1000), Curve curve = Curves.easeOut, Duration delayBetweenChars = const Duration(milliseconds: 40), double sigmaFrom = 8.0, double sigmaTo = 0.0})
Creates a blur transition 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 blur animations, transitioning from sigmaFrom to sigmaTo based on staggered progress.
override
getTotalDuration(int charCount) Duration
Returns the total duration needed to animate all charCount characters.
inherited
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.
