Methods

addEventListener(String type, EventListener listener, [ bool useCapture ]) → void inherited

after(Object nodes) → void inherited

animate(Iterable<Map<String, dynamic>> frames, [ dynamic timing ]) → Animation @SupportedBrowser(SupportedBrowser.CHROME, '36'), inherited

Creates a new AnimationEffect object whose target element is the object

on which the method is called, and calls the play() method of the

AnimationTimeline object of the document timeline of the node document

of the element, passing the newly created AnimationEffect as the argument

to the method. Returns an Animation for the effect.

Examples

var animation = elem.animate([{"opacity": 75}, {"opacity": 0}], 200);

var animation = elem.animate([

{"transform": "translate(100px, -100%)"},

{"transform" : "translate(400px, 500px)"}

], 1500);

The frames parameter is an Iterable, where the

map entries specify CSS animation effects. The

timing paramter can be a double, representing the number of milliseconds

for the transition, or a Map with fields corresponding to those

of the Timing object.
