Description Of Changes

search item 을 이용하여 groupChannel 진입시 lazyScrollToIndex를 이용하여 스크롤 처리를 하는데 다음과 같은 문제가 있습니다

1. lazyScrollToIndex 내부에서 timeout 딜레이를 주고 scrollToIndex 를 호출기전에 messages가 변경되면 index가 맞지 않은 문제
2. FlatList에서 내부 조건에 의해 onBottomReached를 호출하는데 collection의 cacheResult 와 apiResult 사이에 onBottomReached 로 인해 loadNext가 호출되면서 FlatList 내부 Data가 변경되며 scroll이 정상정으로 되지 않는 문제

해결방법
search item 을 이용해서 scroll 이 필요할때 lazyScrollToIndex 말고 messageId를 이용 해서 스크롤 순간에 index를 찾도록 수정
FlatList 내부 조건에 의해 onBottomReached 가 호출될때 hasNext 와 search item을 이용한 스크롤 중인지 체크해서 처리

Pull Request Overview

This PR resolves a search item scroll issue by implementing a new lazy scrolling mechanism for message lists. The fix introduces asynchronous scrolling to prevent timing issues when scrolling to specific messages before data rendering has been committed.

• Adds a new lazyScrollToMessageId function for scrolling to messages by ID with proper timing
• Replaces index-based scrolling with message ID-based scrolling for search functionality
• Implements throttling logic for bottom-reached events to prevent excessive API calls during scrolling

이건 첫 데이터 로드에서 찾은 index 는 스크롤로 가는 도중에 load more 등으로 리스트가 업데이트 되면
index 가 바뀌니, ref 를 사용해서 해당 시점의 messages 스냅샷에서 정확한 index 를 찾아서 이동하는것 맞을까요?

[OnestarLee]

네 현재 상태에서는 onBottomReached 가 loadNext를 호출하면서 문제가 발생하고있습니다. 어떤 경우라도 messages 가 변경되었다면 현재 messages 기준으로 인덱스를 다시 찾아야 스크롤 처리해주는게 기대 동작일것 같습니다

lgtm! 고생하셨습니다.
