public class ScalingLazyListState constructor(
private var initialCenterItemIndex: Int = 1,
private var initialCenterItemScrollOffset: Int = 0,
) : ScrollableStateA state object that can be hoisted to control and observe scrolling.
In most cases, this will be created via rememberScalingLazyListState.
If the developer wants custom control over position and spacing they can switch off autoCentering and provide contentPadding.
Note that it is not always possible for the values provided by initialCenterItemIndex and initialCenterItemScrollOffset to be honored, e.g. If initialCenterItemIndex is set to a value larger than the number of items initially in the list, or to an index that can not be placed in the middle of the screen due to the contentPadding or autoCentering properties provided to the ScalingLazyColumn. After the ScalingLazyColumn is initially drawn the actual values for the centerItemIndex and centerItemScrollOffset can be read from the state.
Parameters
| initialCenterItemIndex | the initial value for ScalingLazyListState.centerItemIndex, defaults to 1. This will place the 2nd list item (index == 1) in the center of the viewport and the first item (index == 0) before it. |
| initialCenterItemScrollOffset | the initial value for ScalingLazyListState.centerItemScrollOffset |
Properties
centerItemIndex
public val centerItemIndex: IntThe index of the item positioned closest to the viewport center
