This doc sometimes uses both itemsToKey and itemToKey, I assume that only one is correct.

| When `VirtualColumn` renders an item, it calls the `children` render function once and memoizes the result. If an item changes, a new item should be provided with the same key. Items with identical keys, as returned by `itemsToKey`, will update the same React element. |

key is not used here, is it deliberate?
Suggested change
| {(item, key) => <Text>{item.value}</Text>} | |
| {(item, key) => <Text key={key}>{item.value}</Text>} |
