First of all Thx for this Awesome project .
I am trying to use LinePagerIndicatorDecoration with loopingLayout manger . But it does not have a any exposed method for find Visible Item similar to LinearlayoutManager . So i can not get the decorator working i tried to modify loopingLayout but did not succeed . Can you shad some lights on it how i can make it work?
Or its a new feature request .

Hmm it sounds like this is related to #46. Could you explain how you attempted to modify the looping layout, and how it didn't work? Based on this comment from another issue I think we should be able to get something working =)
