Youtube_player_flutter: 调整大小时视频暂停

当动态增加视频播放器的宽度时，它会停止播放。 我希望它会随着尺寸的变化而继续播放。 这将允许用户将视频最小化/最大化到他们自己的大小，而不是使用全屏功能。

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

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  <strong i="6">@override</strong>
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  double width = 100.0;

  <strong i="7">@override</strong>
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Transition Demo',
      home: Scaffold(
          appBar: AppBar(
            title: Text('Demo'),
          ),
          body: Column(
            children: <Widget>[
              YoutubePlayer(
                context: context,
                videoId: "iLnmTe5Q2Qw",
                flags: YoutubePlayerFlags(
                  autoPlay: true,
                  showVideoProgressIndicator: true,
                ),
                width: width,
              ),
              FlatButton(child: Text('Increase'), onPressed: () => setState(()=> width += 10)),
            ],
          ),
        ),
    );
  }
}

单击按钮更改宽度后，控制台输出以下内容。 看起来它正在取消初始化视频，然后重新加载它。
