如何在ScrollView中保住位置？React Native

import React, { useState } from 'react';
import { ScrollView, View, Text } from 'react-native';

const App = () => {
  const [scrollPosition, setScrollPosition] = useState(0);

  const handleScroll = (event) => {
    setScrollPosition(event.nativeEvent.contentOffset.y);
  };

  const handleContentSizeChange = (contentWidth, contentHeight) => {
    scrollViewRef.scrollTo({ y: scrollPosition });
  };

  return (
    <ScrollView
      ref={(ref) => { scrollViewRef = ref; }}
      onScroll={handleScroll}
      onContentSizeChange={handleContentSizeChange}
    >
      <View style={{ height: 1000 }}>
        <Text>Scrollable content goes here</Text>
      </View>
    </ScrollView>
  );
};

export default App;
