Public properties

afterContentPadding

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.

open val mainAxisItemSpacingInt

The spacing between items in the direction of scrolling.

open val orientationOrientation

The orientation of the lazy list.

reverseLayout

open val reverseLayoutBoolean

totalItemsCount

val totalItemsCountInt

The total count of items passed to LazyColumn or LazyRow.

viewportEndOffset

val viewportEndOffsetInt

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.

viewportSize

open val viewportSizeIntSize

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

viewportStartOffset

val viewportStartOffsetInt

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.

visibleItemsInfo

val visibleItemsInfoList<LazyListItemInfo>

The list of LazyListItemInfo representing all the currently visible items.
