如何处理React中的checked in input type='checkbox‘？

class CheckboxComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      isChecked: false
    };
  }

  handleCheckboxChange = () => {
    this.setState(prevState => ({
      isChecked: !prevState.isChecked
    }));
  }

  render() {
    return (
      <input
        type="checkbox"
        checked={this.state.isChecked}
        onChange={this.handleCheckboxChange}
      />
    );
  }
}

class CheckboxComponent extends React.Component {
  constructor(props) {
    super(props);
    this.checkboxRef = React.createRef();
  }

  handleButtonClick = () => {
    const isChecked = this.checkboxRef.current.checked;
    console.log(isChecked);
  }

  render() {
    return (
      <div>
        <input type="checkbox" ref={this.checkboxRef} />
        <button onClick={this.handleButtonClick}>Get Checkbox Value</button>
      </div>
    );
  }
}
