Sir I try to implement a dynamic audio. But when I try to assign the value of specific id to MediaItem object it returns to null. What is the best way to make the audio change depending on what song I want to play?

What do you mean by "assign the value of a specific id to MediaItem object"? i.e. what method are you talking about?

Also when you say "it returns to null", what do you mean by "it"? i.e. What method is returning null?

What is the best way to make the audio change depending on what song I want to play?

If you search through past issues, you may be able to find some advice, but I would suggest using playFromMediaId which you can also use as a search term through past issues.

P.S. When posting issues, please try to make the title brief and put your question in the body of your post as this will make it easier to quote and reply.

Humbly apologize Sir and thanks for reminding me about my lackness.
Actually, I have list of songs fetch from fires base. Then, when I click one of the song that I want to play and get the value assign it into new variable and pass to Mediaitem. Unfortunately, when i assign it a new variable into MediaItem which property ID it will retrun to null. But I printed out the value it exist. I doubt when I click the button play the widget rebuild and so the new variable i used return to null.
Sir, what is the proper way to get the value and put it to MediaItem property ID that will work out?
#ThankYouForYourResponse (y)

final _queue = [
MediaItem(
id: '$currentSongPlay', // this variable returns to null
album: 'Science friday',
title: 'Science friday',
artist: "Science Friday and WNYC Studios",
duration: 5949494,
artUri:
"https://media.wnyc.org/i/1400/1400/l/80/1/ScienceFriday_WNYCStudios_1400.jpg",
),

Did you search through past issues for playFromMediaId?

[unlovedmilds]

Yes Sir, before I post here some of user asked you relate to my problem I tried to implement your suggestion which is playFromMediaId. But it ddnt work out. I think my implementation of code isnt correct. My data source id comes from firebase.
It is a list of songs, Then i pass the specific value to MediaItem to be able to set the id of song.
Is thier another proper way to make the audio song play dyanmic?
BTW, Im using audioplyaers plugin.
Im a begginers and new employee. This task given me to fullfill.
Hope you can help me to figure this problem Sir. :((

audioplayers has recently had compatibility issues with audio_service and so it's possible you might run into issues related to that, although I'm not sure what the issue is here unless you fill in all fields in the bug report template including a minimal reproduction project.

[unlovedmilds]

I tried your example. So that I can compare my working project. In order to understand what's happening why was the global variable which has a value from firebase return null if assign it to
final _queue = [
MediaItem(
id: '$currentSongPlay',
]
I doubt that maybe the passing data from class widget to class AudioPlayerTask that has contain MediaItem isn't the right way. I made a lot of research, passing data to one class to another class.
Its work fine but this scenario made me puzzled alot. :?
My brain was badly drain :((
Im still hoping the solution despite I reach my limitation.
Im looking forward Sir how to able to fix this problem.

Sir this is my UI dart code
If user click play button,

RawMaterialButton(
onPressed: () async {

      AudioService.play()
      AudioService.start(
      backgroundTaskEntrypoint: audioPlayerTaskEntrypoint,
      resumeOnClick: true,
      androidNotificationChannelName: 'Audio Service Demo',
      notificationColor: 0xFF2196f3,
      androidNotificationIcon: 'mipmap/ic_launcher',
    );

}
//This is my value of url from firebase,
String currentSongPlay = '${widget.episode.source}'; // assuming this is global variable

  Now I pass the variable currentSongPlay to 
 class AudioPlayerTask extends BackgroundAudioTask{

  final _queue = [
 MediaItem(
 id: '$currentSongPlay',
 ]

}
Problem : Why is variable currentSongPlay return to null even if i get the value?
No error display, but the background controller display in notification bar w/o audio.
I think deeply, maybe its not allowed to pass data from widget to MediaItem :?

           Is their other way to implement  to play audio dynamically?

As mentioned earlier, I'm not able to investigate the issue until you fill in all fields in the bug report template including a minimal reproduction project.

When I use onCustomAction method to invoke audioPlayers, I got the exception:

E/flutter (13301): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: MissingPluginException(No implementation found for method resume on channel xyz.luan/audioplayers)
E/flutter (13301): #0      MethodChannel.invokeMethod

E/flutter (13301): <asynchronous suspension>
E/flutter (13301): #1      AudioPlayer._invokeMethod  (package:audioplayers/audioplayers.dart:211:10)

But I can use audioPlayers on onStart method, I don't know what difference.
