Which API doesn't behave as documented, and how does it misbehave?
just audio 0.9.41

It is crashing if you close the application while audio players are loaded on iOS.
It is crashing because flutter disposes the just_audio plugin, which causes the players to be disposed.
When players are disposed they send a broadcast event with their current status, which causes a crash report.

Minimal reproduction project

import 'package:flutter/material.dart';
import 'package:just_audio/just_audio.dart';

AudioPlayer? _tapAudioCache;
void main() async{
  WidgetsFlutterBinding.ensureInitialized();

  runApp( MaterialApp(
    title: 'Flutter Demo',
    home: Center(
      child: ElevatedButton(onPressed: () async{
        _tapAudioCache = await initEffectsCache('christmas1.mp3');
        _tapAudioCache!.play();
      }, child: const Text('Play Sound')),
    ),
  ));
}
Future<AudioPlayer> initEffectsCache(String filePath, {double volume = 1}) async {

  var player = AudioPlayer();
  await player.setUrl('asset:assets/sounds/$filePath', );
  await player.setVolume(volume);

  return player;
}

To Reproduce (i.e. user steps, not code)
Steps to reproduce the behavior:

  1. Launch the application
  2. Press the 'Play Sound' button
  3. On the device swipe up and close the application
  4. An exception will trigger (you can catch it with xcode attached, see screenshot)

Error messages

Exception	NSException *	"Sending a message before the FlutterEngine has been run."	0x0000600000c90f60

Expected behavior
The application should not crash when terminating the application while players are loaded.
There is no need for players to report their state when terminating the app.
The crash reports are being sent to Apple, Crashlytics etc. ... there is no need for that.

Same issue on all my Radio apps.

You can live reproduce it using one of my little app : "Zim Radio" on AppStore (https://apps.apple.com/sn/app/zim-radio/id1290256398).

Steps :

  • Launch App
  • Wait audio start
  • Kill app
  • Wait a bit

Current result:

After few seconds a native iOS popup appear saying app has crashed

Expected results:

Nothing should happen ,app should be killed, audio stopped without issue.

Device :

iPhone SE 2gen
iOS 18
XCode 16

On flutter i didn't see any interesting logs except this one which appear when app is killed :

@EArminjon @cristian1980, can you explain the changes a bit? , as I am a flutter plus android developer not able to understand ios framework changes lot.

In Objective C we are getting a dealloc function that is called when the receiving object is about to be removed from RAM.
When dealloc is called for just_audio plugin, the plugin tries to send audio players states(position, play/paused/stopped) to your flutter app.
The problem is that your flutter app is probably already terminated because the entire flutter engine is shutting down, and the flutter engine is the one that unloaded the just_audio in the first place.
Sending messages to the flutter engine that will forward it to you flutter app, in the shutting down state, seems to be causing a crash.

For the fix I added a parameter to dispose method so I know that dispose was called from dealloc so I don't send player states when the flutter engine is shutting down.

Thank you, @cristian1980 ! Your explanation worked perfectly for my app. I was able to modify the just_audio package and integrate it successfully. You've saved my day! 🙌

Great @richanshah . Note however that you didn't need to modify anything, because @cristian1980 indicated he made a fork here #1350 (comment) - so all you really needed to do was to use it. For example, by modifying your pubspec.yaml to look like this:

just_audio:
    git:
      url: https://github.com/cristian1980/just_audio
      ref: minor
      path: just_audio

@jonmountjoy @cristian1980 Thanks for the patch. It seems to work for me on iOS. On macOS I'm getting a compilation error though:

@cristian1980 I think you need to update the definition of dispose in the header as well as the implementation, here:

just_audio/just_audio/macos/Classes/AudioPlayer.h

Line 10 in 35a33da

- (void)dispose;

@milesegan you are correct, I did not test the fix on MacOS, fixed it on my fork.
