如何在react-native中更改动画中的文本？

import React, { Component } from 'react';
import { Animated, Text, View } from 'react-native';

class AnimatedTextExample extends Component {
  constructor(props) {
    super(props);
    this.animatedValue = new Animated.Value(0);
  }

  componentDidMount() {
    Animated.timing(this.animatedValue, {
      toValue: 1,
      duration: 1000,
      useNativeDriver: true,
    }).start();
  }

  render() {
    const textSize = this.animatedValue.interpolate({
      inputRange: [0, 1],
      outputRange: [20, 40],
    });

    return (
      <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
        <Animated.View style={{ opacity: this.animatedValue }}>
          <Animated.Text style={{ fontSize: textSize }}>
            Hello, World!
          </Animated.Text>
        </Animated.View>
      </View>
    );
  }
}

export default AnimatedTextExample;
