public abstract class TransitionPropagation
extends Object

   ↳ androidx.transition.TransitionPropagation

Extend TransitionPropagation to customize start delays for Animators created in Transition.createAnimator(ViewGroup, TransitionValues, TransitionValues). A Transition such as Explode defaults to using CircularPropagation and Views closer to the epicenter will move out of the scene later and into the scene sooner than Views farther from the epicenter, giving the appearance of inertia. With no TransitionPropagation, all Views will react simultaneously to the start of the transition.
