Youtube_player_flutter: サイズ変更時のビデオの一時停止

ビデオプレーヤーの幅を動的に増やすと、再生が停止します。 サイズが変わっても再生が続くと思います。 これにより、ユーザーはフルスクリーン機能を使用する代わりに、ビデオを自分のサイズに最小化/最大化することができます。

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)),
            ],
          ),
        ),
    );
  }
}

ボタンをクリックして幅を変更すると、コンソールは次のように出力します。 動画の初期化を解除してから再読み込みしているようです。
