simple_audio 1.0.2

A cross-platform solution for playing audio in Flutter.

Simple Audio

A cross-platform solution for playing audio in Flutter.

This project's goal is to be as simple as possible, meaning it offers the core functionality only (ex. play/pause). It also aims to be stable and relatively bug free.

I created this plugin for my music app so that I don't have to use different packages for different platforms (audio_service, dart_vlc). This made it hard to deal with bugs from different packages.

Features

• Simple API
• Cross platform (Android, Linux, Windows, iOS, macOS)
• Media notifications on all platforms to access controls (iOS and macOS use the control center)
• Playback of local and online resources

Usage

• Add this plugin as a dependency in pubspec.yaml
• Call SimpleAudio.init() in main() and configure as you need.
• Instantiate a SimpleAudio object in your player controller.
• Use the APIs provided in the instantiated object.

To see a sample player project, please check the example.

Setup

Some platform specific things have to be set up in order for this plugin to function properly.

Windows/Linux

No setup is needed for these platforms.

Android

You will need to edit 2 files located in the android/app/src/main directory.

AndroidManifest.xml

<!-- Add this permission. -->
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
<application>
  <!-- ... -->
  
  <!-- This is required if you want to be able to see the notification. -->
  <service
      android:name="com.erikas.simple_audio.SimpleAudioService">
  </service>

  <!-- This is required to interact with the notification buttons. -->
  <receiver
      android:name="com.erikas.simple_audio.SimpleAudioReceiver">
  </receiver>
  
</application>

MainActivity.kt

// ...
// Add these imports.
import android.content.Intent
import android.os.Bundle
import com.erikas.simple_audio.SimpleAudioService
import com.erikas.simple_audio.notificationClickedIntent

class MainActivity: FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?)
    {
        super.onCreate(savedInstanceState)

        // This line is optional. What it does is open your app when the notification
        // is clicked.
        notificationClickedIntent = Intent(applicationContext, MainActivity::class.java)
        // This line starts the SimpleAudioService which starts a foreground service
        // and creates a new media session.
        startService(Intent(applicationContext, SimpleAudioService::class.java))
    }
}

iOS

You will have to add a dependency to your Xcode project.

• Open Runner.xcworkspace in the ios folder.
• At the top of your project hierarchy view, select the Runner project.
• Select the Runner target, go to the General tab and scroll down until you see Frameworks, Libraries, Embedded Content
• Press the + icon and add the AudioToolbox.framework framework. Select Do Not Embed under the Embed column.

Add this to your Info.plist file located in ios/Runner:

<dict>
  <!-- ... -->
  <key>UIBackgroundModes</key>
  <array>
    <string>audio</string>
  </array>
</dict>

macOS

You will need to update the macOS build versions to 10.13

• Open Runner.xcworkspace in the macos folder.
• At the top of your project hierarchy view, select the Runner project.
• In your Runner project, go to the Info tab and set macOS Deployment Target to 10.13
• Select the Runner target and set the Minimum Deployments macOS version to 10.13
