ImplicitAnimate class

Animates changes to the endpoints of Fade, Scale, Slide and Move effects.

Each effect has an independent clock. A changed end transitions from the currently displayed value; begin is used only when the chain is mounted. Effects are matched by position and exact type. Changing the chain's length or types resets the whole chain. Use a new key to reset an unchanged shape.

This is an opt-in alternative to Animate, without timeline controls. Unsupported effects and reverseCurve throw ArgumentError. Reduced motion from MediaQuery applies endpoints immediately and cancels pending delays.

Methods

addEffect(Effect effect) → ImplicitAnimate

override

addEffects(List<Effect> effects) → ImplicitAnimate

inherited

animate({Key? key, List<Effect>? effects, AnimateInitCallback? onInit, AnimateCallback? onPlay, AnimateCallback? onComplete, bool? autoPlay, Duration? delay, AnimationController? controller, Adapter? adapter, double? target, double? value, bool preRenderZeroDuration = false}) → Animate

Available on Widget, provided by the AnimateWidgetExtensions extension

Wraps the target Widget in an Animate instance, and returns the instance for chaining calls. Ex. myWidget.animate() is equivalent to Animate(child: myWidget).

animateImplicitly({Key? key, List<Effect>? effects}) → ImplicitAnimate

Available on Widget, provided by the ImplicitAnimateWidgetExtensions extension

Wraps this widget in ImplicitAnimate. Only Fade, Scale, Slide and Move effects are supported; existing shorthand extensions construct those types.

createElement() → StatefulElement

Creates a StatefulElement to manage this widget's location in the tree.

inherited

createState() → State<ImplicitAnimate>

Creates the mutable state for this widget at a given location in the tree.

override

debugDescribeChildren() → List<DiagnosticsNode>

Returns a list of DiagnosticsNode objects describing this node's children.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String

Returns a string representation of this node and its descendants.

inherited

toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A short, textual description of this widget.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
