如何使矩形具有动画宽度React Native

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

class AnimatedRectangle extends Component {
  constructor(props) {
    super(props);
    this.state = {
      widthAnimation: new Animated.Value(0), // 初始化动画值为0
    };
  }
}

componentDidMount() {
  Animated.timing(this.state.widthAnimation, {
    toValue: 200, // 动画结束时的宽度值
    duration: 1000, // 动画持续时间
    useNativeDriver: false, // 是否使用原生驱动器（需要设置为false）
  }).start(); // 启动动画
}

render() {
  const { widthAnimation } = this.state;

  return (
    <View>
      <Animated.View style={{ width: widthAnimation }}>
        {/* 矩形的内容 */}
      </Animated.View>
    </View>
  );
}
