Feature Request: itemUnloading event similar to itemLoading event #24

I could not find anything similar to this, it would be helpful to have an event for when an item is no longer being displayed as a view to free up any tasks/intervals related to it.

@garsuga such évent is not really possible seeing how collection view works. views are reused. so you wouly not always get the event

Sorry, I worded that poorly. I was interested in an event that would tell when at item has its view bound to a new item. That way you can tell when an item is no longer bound to a view.

https://developer.android.com/reference/kotlin/androidx/recyclerview/widget/RecyclerView.RecyclerListener This is an event that happens when a view is being recycled, I was hoping for an event at the same time which would return the item which was replaced when the view was recycled.

@garsuga ok the thing is i want the component to remain as lean as possible for it be fast. What you could do is:

clone this repo
create a new package inside packages (a new plugin)
add the functionnality so that we can release it as a collectionview extension
make a PR

Would that we good with you?
