Firebase Notification does NOT show up when app is open

Question

In my testing, when send out Firebase Notification to Android, the notification does NOT show up when the user has the app open on the screen. Is this a default behavior?

What should I do if I want the user to always receive notification no matter they have the app open or not?

can you add your notification (Firebase Messaging) class code? — HussainAbbas, May 09 '20 at 22:48
that's why...you need to add ```Firebase Messaging``` class in your project here is the reference https://firebase.google.com/docs/cloud-messaging/android/receive — HussainAbbas, May 10 '20 at 22:41

For notification messages the default behavior is indeed that:

the OS displays them when the app is not active.
they're delivered to your application code when the app is active.

Also see:

The Firebase documentation on message types.
Flutter: Push notifications even if the app is closed, mostly since it shows how to show your own notifications.

So when the app is not running in the background, the user won't get the notification? – user1187968 May 09 '20 at 22:44
That'd be the first case/bullet point: if the app is inactive, the system handles display of notifications. – Frank van Puffelen May 09 '20 at 23:29
So when the app is running on the screen, is there a way we can force the notification to show up under the Android notification tray? – user1187968 May 10 '20 at 04:29
Check that second link under "Also see" in my asnwer, which contains a link to a library that does precisely that as far as I can see. – Frank van Puffelen May 10 '20 at 14:06
