Attempting to use the Firebase Cloud Messaging Plugin on Android, I got it to work while the application is in Foreground or when it is in background (Notification Center).

However messages don't seem to arrive if the application is killed. Am a bit confused so am unsure if this is expected behavior.

Does this mean that if I want the user to receive the notifications the app must at least be in background? Is there a way that even if the app is not in background that the notification will arrive?
