Public properties
afterAutoCenteringPadding
val afterAutoCenteringPadding: Int
The auto centering padding in pixels applied after the last item in the direction of scrolling. For example it is a bottom auto centering padding for ScalingLazyColumn with reverseLayout set to false.
afterContentPadding
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 ScalingLazyColumn with reverseLayout set to false.
anchorType
val anchorType: ScalingLazyListAnchorType
How to anchor list items to the center-line of the viewport
beforeAutoCenteringPadding
val beforeAutoCenteringPadding: Int
The auto centering padding in pixels applied before the first item in the direction of scrolling. For example it is a top auto centering padding for ScalingLazyColumn with reverseLayout set to false.
beforeContentPadding
val beforeContentPadding: Int
The content padding in pixels applied before the first item in the direction of scrolling. For example it is a top content padding for ScalingLazyColumn with reverseLayout set to false.
reverseLayout
val reverseLayout: Boolean
True if the direction of scrolling and layout is reversed.
totalItemsCount
val totalItemsCount: Int
The total count of items passed to ScalingLazyColumn.
viewportEndOffset
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.
viewportSize
val viewportSize: IntSize
The size of the viewport in pixels. It is the scaling lazy list layout size including all the content paddings.
viewportStartOffset
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.
visibleItemsInfo
val visibleItemsInfo: List<ScalingLazyListItemInfo>
The list of ScalingLazyListItemInfo representing all the currently visible items.
