please see the thread HorizontalScrollList with different distances. It possibly addresses similar application case but using a horizontal list instead of vertical list. I hope it helps you as a starting point.
Please note that list components are limited to items with equal size. The above mentioned chapter explains a workaround to display the centered item with other size. With version 12 we have reworked the list components adding support for flexible sized items. The new version 12 will be released soon.
