callPoolingContainerOnRelease
fun View.callPoolingContainerOnRelease(): Unit

callPoolingContainerOnReleaseForChildren
fun ViewGroup.callPoolingContainerOnReleaseForChildren(): Unit
Calls PoolingContainerListener.onRelease on any PoolingContainerListeners attached to any of its children (not including the ViewGroup itself)

listener: PoolingContainerListener
): Unit

Extension properties
isPoolingContainer
var View.isPoolingContainer: Boolean
Whether this View is a container that manages the lifecycle of its child Views.
Any View that sets this to true must call callPoolingContainerOnRelease on child Views before they are discarded and may possibly not be used in the future. This includes when the view itself is detached from the window, unless it is being held for possible later reattachment and its children should not release their resources.
Warning: Failure to call callPoolingContainerOnRelease when a View is removed from the hierarchy and discarded is likely to result in memory leaks!
isWithinPoolingContainer
val View.isWithinPoolingContainer: Boolean
Whether one of this View's ancestors has isPoolingContainer set to true
