React-native-animatable: transition or transitionTo's callback

[monzy613]

Hi, I want to have a callback using transition(from, to), but this transition func return undefined..
also I tried onAnimationEnd, it's not fired

Seems like this would be pretty easy to write. I tried doing it with a promise but I don't really know how those work exactly.. I accomplish my goal with a timeout

var duration = 2000

    this.refs.Card.transitionTo({height:150},duration)

    setTimeout(()=> {
      console.warn('transition done')
    },duration)

can we have a promised like function for this? something like:

transitionTo(params).then(() => console.log(’transition done’))

@kevando Indeed it's a workaround.. but not look very nice

I hope I can use callback or promise then.
Because too many setTimeout will make my animation slower and pause sometimes.

onTransitionBegin and onTransitionEnd are now available in 1.3.0.

I still want to have a promise, using onTransitionEnd may deal with other situations.
