totalItemsCount
abstract val totalItemsCount: Int
The total count of items passed to LazyColumn or LazyRow.
viewportEndOffset
abstract val viewportEndOffset: Int
The end offset of the layout's viewport. You can think of it as a maximum offset which would be visible. Usually it is a size of the lazy list container plus a content padding.
You can use it to understand what items from visibleItemsInfo are fully visible.
viewportStartOffset
abstract val viewportStartOffset: Int
The start offset of the layout's viewport. You can think of it as a minimum offset which would be visible. Usually it is 0, but it can be negative if a content padding 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.
