Animation Callbacks

Go back to Tutorial

A callback is fired when an animation is started and also when it is done.

In the keyframes example, you have a trigger called @flyInOut. You can hook those callbacks like this:

hero-list-multistep.component.ts (excerpt)

template: `

<ul>

<li *ngFor=”let hero of heroes”

(@flyInOut.start)=”animationStarted($event)”

(@flyInOut.done)=”animationDone($event)”

[@flyInOut]=”‘in'”>

{{hero.name}}

</li>

</ul>

`,

The callbacks receive an AnimationEvent that contains useful properties such as fromState, toState and totalTime.

Those callbacks will fire whether or not an animation is picked up.
