Make method to retrieve offset of widget public in AutoScrollController #43

Closed bejaeger closed 3 years ago

Hi,

first of all, thanks for providing this package, this saved me a lot of time. I'm using the AutoScrollController in a CustomScrollVIew. I would like to change the opacity of a widget dependent on the scroll position. Is it possible to retrieve the offset of a specific index tagged with AutoScrollTag so I don't have to calculate the position myself? It seems like this feature must be already implemented in the AutoScrollController and would just be needed to make public.

Thanks in advance. Benjamin!
