play YouTube channel audio in the background when the app is minimised in Flutter

 To play YouTube channel audio in the background when the app is minimized in Flutter, you can use the flutter_youtube package.

Here is an example of how you can use this package to play a YouTube channel in the background:

1. First, add the flutter_youtube package to your pubspec.yaml file:

dependencies:
  flutter_youtube: ^1.0.3

2. Next, import the package in your Dart code:

import 'package:flutter_youtube/flutter_youtube.dart';

3. You can then use the FlutterYoutube.playYoutubeVideoById() method to play a YouTube video by its ID. For example:

FlutterYoutube.playYoutubeVideoById(
  apiKey: "YOUR_API_KEY",
  videoId: "VIDEO_ID",
  autoPlay: true,
  fullScreen: false,
);

4. To play a YouTube channel in the background, you can use the FlutterYoutube.playYoutubeVideoById() method in conjunction with a timer to play the next video in the channel.

Here is an example of how you can do this:

import 'dart:async';

// ...

Timer _timer;
String _currentVideoId = "VIDEO_ID";

void playNextVideo() {
  // Stop the current timer
  if (_timer != null) {
    _timer.cancel();
  }

  // Play the next video in the channel
  FlutterYoutube.playYoutubeVideoById(
    apiKey: "YOUR_API_KEY",
    videoId: _currentVideoId,
    autoPlay: true,
    fullScreen: false,
  );

  // Set up a new timer to play the next video in the channel
  // after the current video has finished playing
  _timer = Timer(Duration(minutes: 30), playNextVideo);
}

// Start playing the first video in the channel
playNextVideo();

This code will play the first video in the channel, and then play the next video in the channel every 30 minutes.
