Methods

addEventListener(String type, EventListener listener, [ bool useCapture ]) → void
inherited
after(Object nodes) → void
inherited
animate(Iterable<Map<String, dynamic>> frames, [ dynamic timing ]) → Animation
  • 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.
