import 'package:youtube_player_flutter/youtube_player_flutter.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: YoutubePlayer(
            controller: YoutubePlayerController(
              initialVideoId: 'YOUR_VIDEO_ID',
              flags: YoutubePlayerFlags(
                autoPlay: true,
                mute: false,
              ),
            ),
          ),
        ),
      ),
    );
  }
}

Replace 'YOUR_VIDEO_ID' with the actual ID of the YouTube video you want to display.

4. Embedding YouTube Videos

To embed a YouTube video in your Flutter app, use the YoutubePlayer widget and provide the video ID.

  },
  onPaused: (data) {
    // Do something when the video is paused
  },
  // ...
),

6. Customizing the YouTube Player
