Get item on beforeChange and afterChange events

How can I get the item from the slide if either the beforeChange or afterChange event is fired?

So rather than:

pswp.listen('afterChange', function() { });

It be:

pswp.listen('afterChange', function($item) { });

pswp.currItem

Note : beforeChange gives you the indexDifference as first parameter.

So if you just opened the gallery, it will be null. If you went from 0 -> 1, it will be 1. You can get the previous index with :

         pswp.listen('beforeChange', function(indexDiff) {
                  var previousItem = (pswp.getCurrentIndex() - indexDiff);
         });
