How to use firstItemIndex in Virtuosogrid (bi-direction scrolling)

[qsoo]

I'm using the VirtuosoGrid component. When I prepend the data, I want to focus the current item index, how can I work around this?

The UI I want to implement

List of images

• Lists can be of variable size (height)
• Fetches a list of subsequent pages from the end of the current page (endReached).
• Fetches the list of previous pages from the beginning of the current page (startReached).
• If there are no previous/after pages, the list is no longer retrieved.

Here's what I found

• Virtuoso can be prepended via the firstItemIndex props, but VirtuosoGrid does not have this props.
• prepend data pushes the index of the current item, making the current top item invisible(moved to the bottom).

I need to display a list of images in a grid, so I think VirtuosoGrid is the most appropriate component. Is there an workaround or a method/package you can recommend?
