| onHeightChange? | () => void | Must be called whenever a list item's height changes (for example, when a user clicks an "Expand"/"Collapse" button of a list item): it re-measures the item's height and updates VirtualScroller layout. Every change in an item's height must come as a result of changing some kind of a state, be it the item's state in VirtualScroller via .onItemStateChange(), or some other state managed by the application. Call this method to re-measure the current element. | VirtualScrollerItemProps.onHeightChange | 
| onStateChange? | ( state) =>void | Save current state and when the component re-mount restore previous state using props. It is used to keep a copy of VirtualScroller state so that it could be quickly restored in case the VirtualScroller component gets unmounted and then re-mounted back again — for example, when the user navigates away by clicking on a list item and then navigates "Back" to the list. | VirtualScrollerItemProps.onStateChange |
