How to Play 'Install-time' Delivery Asset pack Mp3 files in flutter?

Question

Hi I'm a newbie for flutter. Plugin - I'm using this plugin.

I'm working on a Flutter project and I'm using Install-time Delivery Asset Packs to manage my assets. I have some MP3 files that are included in the asset pack, and I want to play them in my Flutter application. In light of this, I'm kindly requesting assistance in understanding the correct approach to load and play these MP3 files from an Install-time Delivery Asset Pack in Flutter. Any insights or code snippets would be greatly appreciated.

my pubspec.yaml file like this:

dependencies:
  flutter:
    sdk: flutter
  audioplayers_darwin: ^5.0.1
  cupertino_icons: ^1.0.2
  just_audio_background: ^0.0.1-beta.10
  audio_service: ^0.18.12
  just_audio: ^0.9.35
  flutter_play_asset_delivery: ^0.0.2

Could someone please guide me on how to correctly load and play these MP3 files from an Install-time Delivery Asset Pack in Flutter?
