com.facebook.litho.animation.AnimatedPropertyNode

public class AnimatedPropertyNode
extends ValueNode

A ValueNode that allows getting and/or setting the value of a specific property (x, y, scale, text color, etc) on a given mount content (View or Drawable).

If there is no input hooked up to this node, it will output the current value of this property on the current mount content. Otherwise, this node will set the property of the given mount content to that input value and pass on that value as an output.
