`scrollToIndex` causes blank screen when used with `maintainVisibleContentPosition`

[tannguyen05]

Description

When using the maintainVisibleContentPosition prop together with the scrollToIndex method, the list turns blank and does not scroll to the specified index.
If I remove the maintainVisibleContentPosition prop, then scrollToIndex works as expected.

Environment

• react-native: 0.79.2
• @legendapp/list: 1.0.17

Reproduction

I'll attach a code snippet and a screen recording video demonstrating the issue.

<Button
  title="scroll to index 40"
  onPress={() => {
    listRef.current?.scrollToIndex({
      index: 40,
      animated: true,
    });
  }}
/>
<LegendList
  ref={listRef}
  data={messages}
  keyExtractor={item => `msg-${item.id}`}
  renderItem={renderItem}
  recycleItems={true}
  maintainScrollAtEnd
  alignItemsAtEnd
  maintainVisibleContentPosition
  onStartReachedThreshold={0.1}
  onStartReached={onStartReached}
  onEndReached={({distanceFromEnd}) => {
    if (distanceFromEnd > 0) {
      onEndReached();
    }
  }}
/>

I have the same problem and don't know how to solve it

I have a version 2.0.0-next.2 which makes maintainVisibleContentPosition much more accurate. I'm aiming to release an alpha or beta of next week. That should make scrollToIndex work perfectly as far as I can tell. Give that a try, it might be better?

After installing version 2.0.0-next.2, an error occurs stating "Module '@legendapp/list' not found or its corresponding type declaration is missing."

Oh that's wild... It's working in my apps...

Can you share a repo? Or can you share a screenshot of that error?

I just got that error myself, still not sure why. But 2.0.0-next.3 seems to be working :)
