How to Add Media Items to a Queue and Play Them in Flutter: A Step-by-Step Guide

Are you tired of struggling to play media items in a queue in your Flutter app? Do you want to create a seamless audio or video playback experience for your users? If so, you’re in the right place! In this article, we’ll take you through a comprehensive guide on how to add media items to a queue and play them in Flutter.

What is the Audio Service Plugin?

Before we dive into the tutorial, it’s essential to understand the Audio Service plugin, which is a popular and powerful plugin for playing media items in Flutter. The Audio Service plugin provides a simple and efficient way to play audio and video files, including online streams, local files, and even YouTube videos!

With the Audio Service plugin, you can create a queue of media items and play them one after another. You can also control the playback, pause, and stop the media items, and even display the media item’s metadata, such as the title and artist.

Adding the Audio Service Plugin to Your Flutter Project

To get started, you need to add the Audio Service plugin to your Flutter project. Follow these steps:

1. Open your Flutter project in an editor or IDE.
2. Add the following dependency to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  audio_service: ^0.18.0

3. Run the following command in your terminal:

flutter pub get

Creating a Media Item

Now that you have the Audio Service plugin installed, let’s create a media item. A media item can be an audio or video file, an online stream, or even a YouTube video. For this example, we’ll create a media item from a local audio file.

Here’s an example:

import 'package:audio_service/audio_service.dart';

MediaItem mediaItem = MediaItem(
  id: '1',
  title: 'My Song',
  artist: 'John Doe',
  album: 'My Album',
  duration: Duration(milliseconds: 300000),
  artUri: Uri.parse('https://example.com/cover.jpg'),
  uri: Uri.parse('https://example.com/audio.mp3'),
);

In this example, we’ve created a media item with the title “My Song”, artist “John Doe”, album “My Album”, and a duration of 5 minutes. We’ve also set the artwork URI and the audio file URI.

Creating a Queue of Media Items

Now that we have a media item, let’s create a queue of media items. To do this, we’ll create a list of media items and add them to the queue.

List queue = [
  MediaItem(
    id: '1',
    title: 'My Song 1',
    artist: 'John Doe',
    album: 'My Album 1',
    duration: Duration(milliseconds: 300000),
    artUri: Uri.parse('https://example.com/cover1.jpg'),
    uri: Uri.parse('https://example.com/audio1.mp3'),
  ),
  MediaItem(
    id: '2',
    title: 'My Song 2',
    artist: 'Jane Doe',
    album: 'My Album 2',
    duration: Duration(milliseconds: 400000),
    artUri: Uri.parse('https://example.com/cover2.jpg'),
    uri: Uri.parse('https://example.com/audio2.mp3'),
  ),
  MediaItem(
    id: '3',
    title: 'My Song 3',
    artist: 'Bob Smith',
    album: 'My Album 3',
    duration: Duration(milliseconds: 500000),
    artUri: Uri.parse('https://example.com/cover3.jpg'),
    uri: Uri.parse('https://example.com/audio3.mp3'),
  ),
];

In this example, we’ve created a list of three media items and added them to the queue.

Playing the Media Items in the Queue

Now that we have a queue of media items, let’s play them! To do this, we’ll use the Audio Service plugin’s play() method.

import 'package:audio_service/audio_service.dart';

// Create an instance of the Audio Service
final _audioService = AudioService();

// Play the media items in the queue
_audioService.play(queue);

In this example, we’ve created an instance of the Audio Service and called the play() method, passing the queue of media items as an argument.

Controlling the Playback

Now that the media items are playing, you can control the playback using the Audio Service plugin’s methods. Here are some examples:

Method	Description
play()	Starts playing the media items in the queue.
pause()	Pauses the playback.
stop()	Stops the playback and clears the queue.
skipToNextItem()	Skips to the next media item in the queue.
skipToPreviousItem()	Skips to the previous media item in the queue.
seek(Duration position)	Seeks to a specific position in the current media item.

These are just some of the methods available in the Audio Service plugin. You can use them to create a custom media player with features like playback control, seeking, and more!

Displaying the Media Item’s Metadata

Finally, let’s display the media item’s metadata, such as the title, artist, and album. You can use the Audio Service plugin’s mediaItem() method to get the current media item and display its metadata.

import 'package:audio_service/audio_service.dart';

// Get the current media item
MediaItem currentMediaItem = _audioService.mediaItem;

// Display the media item's metadata
Text(
  '${currentMediaItem.title} - ${currentMediaItem.artist} - ${currentMediaItem.album}',
  style: TextStyle(fontSize: 18),
)

In this example, we’ve gotten the current media item using the mediaItem() method and displayed its title, artist, and album using a Text widget.

Conclusion

And that’s it! You now know how to add media items to a queue and play them in Flutter using the Audio Service plugin. With this knowledge, you can create a seamless audio or video playback experience for your users.

Remember to explore the Audio Service plugin’s documentation for more features and options, such as handling errors, displaying the media item’s artwork, and more!
