Hi @dtkdt100,

Your added code will only run when the alarm is set to sound at the precise moment it is activated. Is this what you want ? What's the use case ?

[dtkdt100]

@gdelataillade For me the use case is:
I am developing an app that do alarm by GPS and when the user will arrive at the right location I want the alarm to ring now.

Also, in your example app there is a button for "Ring now", so I tought if it is in your example app it must be used for something

[gdelataillade]

Hi @dtkdt100,

OK I see. The NOW button in the example is to show the proof-of-concept.

[gdelataillade]

Did you make some tests ? Your code works good ?

[dtkdt100]

@gdelataillade Yes.

Tests:

1. Rings now (as you can see in the video)
2. Set an alarm for one min later (works fine, alarm and notificaiton are working good)

[gdelataillade]

Does your GPS app has to ring even if the app is on background ?

[dtkdt100]

Indeed.
I am using fullScreenIntent: true in FlutterLocalNotificaion and AudioSession in Android or VolumeController in iOS in oder to set the volume up as suggested in #37

[gdelataillade]

With the code you added, are you sure the alarm will ring in the background ? Because the point of using AndroidAlarmManager is to be able to run the Flutter code even if the app is on background.

[dtkdt100]

Yes it is working for me. But i am not sure if it is because of fullScreenIntent: true.

But in this case there is not option that the phone will be in background because when you start the alarm the app will be in foreground, the alarm rings immediately

[gdelataillade]

OK cool, then give me a few days to run some tests and take a look at fullScreenIntent: true. I'll keep you updated. In the meantime you can use your fork for your project.

Thanks for your work.

[dtkdt100]
