loadMoreOffsetFromBottom → int
Determines when the list view should attempt to load more items based on of the index of the item is scrolling into view This is relative to the bottom of the list and has a default value of 0 so that it loads when the last item within the list view scrolls into view. As an example, setting this to 1 would attempt to load more items when the second last item within the list view scrolls into view
