notification controls like audio service in just_audio_background

[yagnik-flunzydigital]

Is your feature request related to a problem? Please describe.
Yes. I am building an audio player application that requires both an in-app player UI and a media notification with synchronized controls.

I initially used the audioservice package to get customizable notification controls. However, I faced significant and persistent synchronization issues between the notification and my just_audio player instance, especially on Android 12+. These issues made the user experience unreliable.

I then switched to just_audio_background, which solved all the synchronization problems perfectly. It works seamlessly with just_audio. The major limitation, however, is that the notification controls are fixed and cannot be customized. My application requires additional controls in the notification, such as shuffle, repeat mode, and a favorite/like button. The current implementation only shows the standard previous, play/pause, and next controls.

Describe the solution you'd like
I would like the ability to specify which controls are displayed in the media notification. A great way to implement this would be to add a new parameter to the JustAudioBackground.init() method.

This parameter, perhaps named androidControls, could accept a List of AndroidControl enums. This would allow developers to define the exact set and order of controls they need.

Here is an example of how the proposed API could look:

import 'package:just_audio_background/just_audio_background.dart';

await JustAudioBackground.init(
  androidNotificationChannelId: 'com.yourapp.channel.audio',
  androidNotificationChannelName: 'Audio Playback',
  androidNotificationOngoing: true,
  // --- PROPOSED FEATURE ---
  androidControls: [
    AndroidControl.previous,
    AndroidControl.play,
    AndroidControl.next,
    AndroidControl.stop, // Example of adding the stop control
    // It would be great to have other controls available too:
    // AndroidControl.shuffle,
    // AndroidControl.repeat,
  ],
);

To handle custom actions like "favorite", you could perhaps listen to a callback stream from the background service that emits custom event IDs.
