React:如何获取自定义TextInput组件的值？

const [inputValue, setInputValue] = useState('');

const handleInputChange = (event) => {
  setInputValue(event.target.value);
}

return (
  <input type="text" onChange={handleInputChange} />
);

import React, { useState } from 'react';

const ParentComponent = () => {
  const [inputValue, setInputValue] = useState('');

  const handleInputChange = (event) => {
    setInputValue(event.target.value);
  }

  return (
    <div>
      <TextInput onChange={handleInputChange} />
      <p>输入的值为：{inputValue}</p>
    </div>
  );
}

const TextInput = ({ onChange }) => {
  return (
    <input type="text" onChange={onChange} />
  );
}

export default ParentComponent;
