I guess this error is triggering when alarm plugin create/send notification request.

Hi @aykutuludag

Thanks for your feedback.

Just one question before I start to investigate about these issues. Do you use await when you call Alarm.set ? Because these look like thread issues.

[aykutuludag]

Of course. I am setting Alarm.init with await like following:

Future<void> main() async {
  try {
    WidgetsFlutterBinding.ensureInitialized();
    SystemChrome.setPreferredOrientations([
      DeviceOrientation.portraitUp,
      DeviceOrientation.portraitDown,
    ]);

    await Alarm.init();
  } catch (error) {
    print(error);
  }

  runApp(const MyApp());
}

And alarms are setting somewhere in MyApp. Based on code it should await until alarm initialized.

I believe that I fixed this bug. I am not sure, I debugged your app but I couldn't find any error. However I researched the issue and they suggested that issue is about AVAudioSession. Following code may fix the issue.

In SwiftAlarmPlugin.swift

    private func mixOtherAudios() {
        do {
            let audioSession = AVAudioSession.sharedInstance()
            try audioSession.setCategory(.playback, mode: .default, options: [.mixWithOthers])
            try audioSession.setActive(true)
        } catch {
            NSLog("SwiftAlarmPlugin: Error setting up audio session with option mixWithOthers: \(error.localizedDescription)")
        }
    }

    private func duckOtherAudios() {
        do {
            let audioSession = AVAudioSession.sharedInstance()
            try audioSession.setCategory(.playback, mode: .default, options: [.duckOthers])
            try audioSession.setActive(true)
        } catch {
            NSLog("SwiftAlarmPlugin: Error setting up audio session with option duckOthers: \(error.localizedDescription)")
        }
    }

This issue is probably about this crash. https://github.com/gdelataillade/alarm/issues/140

Hi @aykutuludag

I'm not able to see your image you provided in your last message.

OK, I'll try to apply your fix. For the next release.

[aykutuludag]

Huge thanks for your effort. I'm applying v3.0.7 and sending new release. I will share if any bug encounters. Best regards.
