如何在flutter中打开下一页的视频？

import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';

class VideoPage extends StatefulWidget {
  @override
  _VideoPageState createState() => _VideoPageState();
}

class _VideoPageState extends State<VideoPage> {
  VideoPlayerController _controller;

  @override
  void initState() {
    super.initState();
    _controller = VideoPlayerController.network(
        'https://example.com/video.mp4'); // 替换为你的视频URL
    _controller.initialize().then((_) {
      setState(() {});
    });
  }

  @override
  void dispose() {
    super.dispose();
    _controller.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('视频播放'),
      ),
      body: Center(
        child: _controller.value.isInitialized
            ? AspectRatio(
                aspectRatio: _controller.value.aspectRatio,
                child: VideoPlayer(_controller),
              )
            : CircularProgressIndicator(),
      ),
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('首页'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('打开视频'),
          onPressed: () {
            Navigator.push(
              context,
              MaterialPageRoute(builder: (context) => VideoPage()),
            );
          },
        ),
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: HomePage(),
  ));
}
