Is it possible in the future to avoid using scroll change event i guess looping in huge list can be a bit laggy

On the contrary. The scroll change event is used to limit the drawing to the visible area.

Make sure to test it in release mode.

I am suggesting to use visible change event instead to avoid looping to the whole list. i tried to play around but i see it needs the offset of the item to draw the text. I have tested with 100 items works fine and smooth but with 1000 items can be a bit laggy since scroll change event loops through the whole list

The scroll changed is required here as we don't want to draw full items if that isn't needed.

I don't think that the lag is related to that loop but you can optimize it and only go over the visible items. It is a simple change.

More importantly is to implement lazy loading and only add visible items.
