如何在不使用任何其他库和插件的情况下在react导航中创建闪屏

import React, { Component } from 'react';

class SplashScreen extends Component {
  render() {
    return (
      <div className="splash-screen">
        {/* Add your custom splash screen content here */}
        <img src="logo.png" alt="Company Logo" />
        <div className="loading-animation"></div>
      </div>
    );
  }
}

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

  componentDidMount() {
    setTimeout(() => {
      this.setState({ showSplashScreen: false });
    }, 3000); // Set the duration of splash screen in milliseconds
  }

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

    return (
      <div className="app">
        {showSplashScreen ? <SplashScreen /> : <Navigation />}
      </div>
    );
  }
}

export default App;
