有没有一种方法可以播放之前在flutter中停止的视频？

dependencies:
  flutter:
    sdk: flutter
  video_player: ^2.2.5

import 'package:video_player/video_player.dart';

VideoPlayerController _controller;

@override
void initState() {
  super.initState();
  _controller = VideoPlayerController.asset('assets/video.mp4');
}

Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text('Video Player'),
    ),
    body: Center(
      child: VideoPlayer(_controller),
    ),
    floatingActionButton: FloatingActionButton(
      onPressed: () {
        setState(() {
          if (_controller.value.isPlaying) {
            _controller.pause();
          } else {
            _controller.play();
          }
        });
      },
      child: Icon(
        _controller.value.isPlaying ? Icons.pause : Icons.play_arrow,
      ),
    ),
  );
}

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