当我离开Flutter的页面时，Chewie视频仍在播放

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

class VideoScreen extends StatefulWidget {
  @override
  _VideoScreenState createState() => _VideoScreenState();
}

class _VideoScreenState extends State<VideoScreen> {
  VideoPlayerController _videoPlayerController;
  ChewieController _chewieController;

  @override
  void initState() {
    super.initState();
    _videoPlayerController = VideoPlayerController.network('https://your-video-url');
    _chewieController = ChewieController(
      videoPlayerController: _videoPlayerController,
      autoPlay: true,
      looping: true,
    );
  }

  @override
  void dispose() {
    _videoPlayerController.dispose();
    _chewieController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Chewie(
      controller: _chewieController,
    );
  }
}
