如何将道具传递给嵌套的路由，因为我在this.props.match中没有定义

<Route path="/parent" component={ParentComponent} />

render() {
  return (
    <div>
      <h1>Parent Component</h1>
      <Route path="/parent" render={(props) => (
        <ChildComponent {...props} customProp="Custom Prop" />
      )} />
    </div>
  );
}

class ChildComponent extends React.Component {
  render() {
    const { customProp } = this.props;

    return (
      <div>
        <h2>Child Component</h2>
        <p>Custom Prop: {customProp}</p>
      </div>
    );
  }
}
