版本"react-native": "0.74.2",

<FlatListstyle={{width: '100%'}}ref={flatListRef}data={list}renderItem={chatItem}keyExtractor={item => item.id}// onScroll={handleScroll}onContentSizeChange={() => {// 内容大小变化时，如果未手动滚动，则滚动到底部// if (!scrollEnabled) {scrollToBottom();// }}}></FlatList>

const scrollToBottom = () => {// console.log('滚到底部');// flatListRef.current?.scrollToEnd({animated: true});(flatListRef.current as any)._listRef._scrollRef.scrollToEnd({animated: true,});};

 使用这个能滚动到底部

(flatListRef.current as any)._listRef._scrollRef.scrollToEnd()
