React-native: [Animated] spring.onComplete function?

[phongyewtong]

If there is a callback for on spring animation complete will be great.

[browniefed]

this.animateValue.spring({}).start(function onComplete() {})

The start call takes a function that is called on complete.

Thanks @browniefed 😀
