Properties

visibleItemsInfo

public val visibleItemsInfo: List<ScalingLazyListItemInfo>

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.

viewportEndOffset

public val viewportEndOffset: Int

The end offset of the layout's viewport in pixels. You can think of it as a maximum offset which would be visible. It is the size of the scaling lazy list layout minus beforeContentPadding.

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