MorphController class

Drives one morphing icon.

Create it with the icon it should paint first; it renders that icon immediately, without animating. Every method is a no-op after dispose.

hashCode → int: The hash code for this object.

hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
isAnimating → bool: True while a spring is running.
no setter
path → Path: The shape to paint right now. Reused across frames — treat as read-only.
no setter
progress ↔ double: Progress of the last painted frame; 1 at rest.
getter/setter pair
reducedMotion ↔ bool: When true, morphTo degrades to set — zero frames.
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.

target → MorphIconData: The icon currently targeted.

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
dispose() → void: Discards any resources used by the object.
override
morphTo(MorphIconData icon, {SpringPreset? preset, double? stiffness, double? damping, Duration? duration}) → void: Springs to icon. Interruptible: called mid-flight it re-plans from the shape currently on screen and carries the spring's velocity across.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
seek(MorphIconData icon, double t) → void: Freezes the morph toward icon at t, without any spring.
set(MorphIconData icon) → void: Paints icon immediately. Zero frames.
toPathD() → String: The current shape as an SVG d attribute.
toString() → String: A string representation of this object.
