removeListener

When you need to remove listening on an animation, you can call removeListener with the string that is returned from addListener.

this._animatedValue = new Animated.Value(0);

var animatedListenerId = this._animatedValue.addListener(
  ({ value }) => (this._value = value)
);

this._animatedValue.removeListener(animatedListenerId);

removeAllListeners

If you happen to attach any number of listeners to an animated value and want to clean up everything, you can simple call removeAllListeners. This will clean up all listeners attached to the Animated value so you don't have a memory leak.

componentWillUnmount: function() {
	this._animatedValue.removeAllListeners()
}
