如何使用React Router在React中不闪烁地重定向？

import React, { Component } from 'react';
import { BrowserRouter as Router, Route } from 'react-router-dom';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      isRedirecting: false
    };
  }

  componentDidMount() {
    setTimeout(() => {
      this.setState({ isRedirecting: true });
    }, 1000);
  }

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

    return (
      <Router>
        <div>
          <Route
            render={() => {
              if (isRedirecting) {
                return <Redirect to="/new-route" />;
              } else {
                return (
                  <div>
                    {/* 正常渲染的内容 */}
                  </div>
                );
              }
            }}
          />
        </div>
      </Router>
    );
  }
}

export default App;
