IconLineShrink class

Shrinks each of the glyph's contours along its long axis by shrink viewBox units (both ends pull in toward the center) and lets it spring back, one at a time in top-to-bottom order. Works well on glyphs with horizontal bars (e.g. a hamburger menu) — each bar briefly shortens in sequence, a clean ripple with no spin.

Each contour is scaled about its own bounding-box center. Rests as the plain icon (restValue 0), so the ripple is an emphasis on tap; reduced-motion shows the static glyph.

Properties

autoReverse → bool
no setterinherited
duration → Duration
Play time for one cycle. The widget sizes its controller to this.
final
hashCode → int
The hash code for this object.
no setterinherited
loops → bool
When true the controller AnimationController.repeats (pair with autoReverse for a ping-pong such as a breathe).
no setterinherited
restValue → double
The progress value to show at rest — when autoplay is off, before the first play, and (crucially) under reduced-motion, which renders this single settled frame instead of animating. e.g. 1.0 for a draw-on that should rest fully drawn, 0.0 for a spin that rests front-facing.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shrink → double
How much (viewBox px) each contour loses off its length at the peak.
final
span → double
Each contour's active window length on the 0..1 timeline; the rest (1 - span) is the one-by-one stagger spread.
final

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size, IconGeometry geom, double t, Paint paint) → void
Paint one frame. size is the icon's viewBox space; t is raw 0..1.
override
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
