Public functions
Public properties
index
val index: Int
The index of the item. When key is provided, this value acts as the last known index. The key is prioritized to identify the item in the presence of dataset changes. If key is null or not found, this index is used instead. The final index used for layout is coerced to stay within the list bounds.
itemEdge
val itemEdge: TransformingLazyColumnFirstLayoutItemProvider.ItemEdge
The logical edge of the item (Start or End) to which offset refers.
key
val key: Any?
The stable key of the item, if one was provided. When specified, this key is prioritized over index to identify the item across content changes (such as item additions or removals), falling back to index only if the key is not found.
offset
val offset: Int
The offset (in pixels) of the item's edge defined by itemEdge.
