Crash on iOS 12

[Wackymax]

Hi,

When trying to run my app on iOS 12 it crashes with the following message:
dyld: Library not loaded: /System/Library/Frameworks/AVFAudio.framework/AVFAudio
Referenced from: /Users/hennie/Library/Developer/CoreSimulator/Devices/E29CF1A8-DF5D-4202-8758-649CEB6077CB/data/Containers/Bundle/Application/BA9BDD13-3C82-4C97-BF4A-E9A4AD758415/Runner.app/Frameworks/audio_session.framework/audio_session
Reason: image not found

Does this also happen on the official example in this repository?

Yes it does crash @ryanheise

How about on an actual device? I want to rule out perhaps an issue with your development environment.

Currently experiencing it on production on all ios devices

Fatal Exception: FlutterError
PlatformException(2003329396, The operation couldn’t be completed. (OSStatus error 2003329396.), null, null). Error thrown null.

flutter doctor?

Our use case

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_) {
      initAudiManager();
    });
  }

  void initAudiManager() {
    try {
      AudioSession.instance.then((audioSession) async {
        // This line configures the app's audio session, indicating to the OS the
        // type of audio we intend to play. Using the "speech" recipe rather than
        // "music" since we are playing a podcast.
        audioSession.devicesChangedEventStream.listen((event) {
          Logger().i('Devices added: ${event.devicesAdded}');
          Logger().i('Devices removed: ${event.devicesRemoved}');
        });
        await audioSession.configure(const AudioSessionConfiguration.music());
      });
    } catch (e) {
      // fail silently
      Logger().e(e);
    }
  }

That is not necessary, because you said the official example already reproduces the bug. I have the official example, I can just use that without using your code.

Still, I need your flutter doctor output because when I run the official example, I don't see the problems you are seeing.

Thanks, I'll check later whether my versions match yours.
