Properties

val visibleItemsInfo: List<LazyListItemInfo>

The list of LazyListItemInfo representing all the currently visible items.

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.

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 lazy list layout minus beforeContentPadding.

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

val totalItemsCount: Int

The total count of items passed to LazyColumn or LazyRow.

val viewportSize: IntSize

The size of the viewport in pixels. It is the lazy list layout size including all the content paddings.

val orientation: Orientation

The orientation of the lazy list.

val reverseLayout: Boolean

True if the direction of scrolling and layout is reversed.

The content padding in pixels applied before the first item in the direction of scrolling. For example it is a top content padding for LazyColumn with reverseLayout set to false.

val afterContentPadding: Int

The content padding in pixels applied after the last item in the direction of scrolling. For example it is a bottom content padding for LazyColumn with reverseLayout set to false.

val mainAxisItemSpacing: Int

The spacing between items in the direction of scrolling.
