Properties

animationName → String

The animationName property of the CSSAnimation interface returns the . This specifies one or more keyframe at-rules which describe the animation applied to the element.

no setter

currentTime ↔ CSSNumberish?

The Animation.currentTime property of the Web Animations API returns and sets the current time value of the animation in milliseconds, whether running or paused.

getter/setter pair, inherited

effect ↔ AnimationEffect?

The Animation.effect property of the Web Animations API gets and sets the target effect of an animation. The target effect may be either an effect object of a type based on AnimationEffect, such as KeyframeEffect, or null.

getter/setter pair, inherited

finished → JSPromise<Animation>

The Animation.finished read-only property of the Web Animations API returns a Promise which resolves once the animation has finished playing.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

id ↔ String

The Animation.id property of the Web Animations API returns or sets a string used to identify the animation.

getter/setter pair, inherited

isDefinedAndNotNull → bool

Available on JSAny?, provided by the NullableUndefineableJSAnyExtension extension

no setter

isNull → bool

Available on JSAny?, provided by the NullableUndefineableJSAnyExtension extension

Whether this value corresponds to JavaScript null.

no setter

isTruthy → JSBoolean

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of !!this in JavaScript.

no setter

isUndefined → bool

Available on JSAny?, provided by the NullableUndefineableJSAnyExtension extension

Whether this value corresponds to JavaScript undefined.

no setter

isUndefinedOrNull → bool

Available on JSAny?, provided by the NullableUndefineableJSAnyExtension extension

no setter

oncancel ↔ EventHandler?

getter/setter pair, inherited

onfinish ↔ EventHandler?

getter/setter pair, inherited

onremove ↔ EventHandler?

getter/setter pair, inherited

pending → bool

The read-only Animation.pending property of the Web Animations API indicates whether the animation is currently waiting for an asynchronous operation such as initiating playback or pausing a running animation.

no setter, inherited

playbackRate ↔ double

The Animation.playbackRate property of the Web Animations API returns or sets the playback rate of the animation.

getter/setter pair, inherited

playState → AnimationPlayState

The read-only Animation.playState property of the Web Animations API returns an enumerated value describing the playback state of an animation.

no setter, inherited

ready → JSPromise<Animation>

The read-only Animation.ready property of the Web Animations API returns a Promise which resolves when the animation is ready to play. A new promise is created every time the animation enters the "pending" play state as well as when the animation is canceled, since in both of those scenarios, the animation is ready to be started again.

no setter, inherited

replaceState → AnimationReplaceState

The read-only Animation.replaceState property of the Web Animations API indicates whether the animation has been removed by the browser automatically after being replaced by another animation.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

startTime ↔ CSSNumberish?

The Animation.startTime property of the Animation interface is a double-precision floating-point value which indicates the scheduled time when an animation's playback should begin.

getter/setter pair, inherited

timeline ↔ AnimationTimeline?

The Animation.timeline property of the Animation interface returns or sets the AnimationTimeline associated with this animation. A timeline is a source of time values for synchronization purposes, and is an AnimationTimeline-based object. By default, the animation's timeline and the Document's timeline are the same.

dispatchEvent(Event event) → bool

The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
