IconBreathe class

A gentle idle "breathe" — the icon scales up and back about its center, on a loop. Cheapest effect in the set: it strokes the crisp un-flattened path once and only applies a uniform Canvas.scale, so there is no per-point transform.

Drive it with a ping-pong controller (loops + autoReverse); the eased t oscillates 0→1→0 for a calm inhale/exhale.

Constructors

IconBreathe({Duration duration = IconMotion.iconBreathe, double amplitude = 0.06, Curve curve = Curves.easeInOut})

const

Properties

amplitude → double

Peak scale increase (0.06 = +6%).

final

autoReverse → bool

no setter, override

curve → Curve

final

duration → Duration

Play time for one cycle. The widget sizes its controller to this.

final

hashCode → int

The hash code for this object.

no setter, inherited

loops → bool

When true the controller AnimationController.repeats (pair with autoReverse for a ping-pong such as a breathe).

no setter, override

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 setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

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.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
