The list of ScalingLazyListItemInfo representing all the currently visible items.

viewportStartOffset

public val viewportStartOffset: Int

The start offset of the layout's viewport in pixels. You can think of it as a minimum offset which would be visible. Usually it is 0, but it can be negative if non-zero beforeContentPadding was applied as the content displayed in the content padding area is still visible.

You can use it to understand what items from visibleItemsInfo are fully visible.
