As you know, notifications with low-priority does not trigger didReceiveRemoteNotification in iOS when app is in background state. I can trigger didReceiveRemoteNotification via using firebase admin rest api via specifying content-available: true and specifying priority as high, but when sending notification from Notification Composer since there is no such option to set priority, no event is emitted. Is there any way to send high priority notification from composer? Btw I am aware of this issue and it says that it is kinda impossible, but still, I guess there should be some workaround to achieve this high-priority feature in notification composer. Thanks in advance!
I expect to be able to send high-priority notification from FCM Notification Composer so it triggers didReceiveRemoteNotification in iOS

Notifications sent from the composer are always high priority.

we're using fcm api to send push notifications to our android/ios/web clients. Clients getting notifications as well but delivery report in firebase console is always zero for received messages. Any idea to show this stat correctly?
In my case that was because of overriding handleIntent function in FirebaseMessagingService. So with removing this function from service the problem fixed.
Thanks to Firebase and FlutterFire, it's easy to send regular notifications from the servers to the users' devices. Those notifications include a title, a body, and an image url. But what about creating a no-that-simple notification, like Telegram's or WhatsApp's?
The simple question is to avoid sending a Notification from the server, and instead set the data field to the push message. But according to the FlutterFire documentation:
Data only messages are considered low priority by devices when your application is in the background or terminated, and will be ignored
So, it sounds like if we want to have a reliable delivery system, we should add a Notification to our push messages. But that notification is so simple. And, again, according to the documentation:
If your message is a notification one (includes a notification property), the Firebase SDKs will intercept this and display a visible notification to your users (assuming you have requested permission & the user has notifications enabled)
So: If I want a reliable system, I have to send Notifications, but I do it, I can't tell FlutterFire to use my custom notifications.
So the question is: how to show custom notifications with FlutterFire?
What I want to achieve is something like this:
I'm going to try setting the priority of the push notification.
You can however explicitly increase the priority by sending additional properties on the FCM payload:
On Android, set the priority field to high.
On Apple (iOS & macOS), set the content-available field to true.
On the server side code, it looks like:
message.setAndroidConfig(AndroidConfig.builder().setPriority(AndroidConfig.Priority.HIGH).build());
message.setApnsConfig(ApnsConfig.builder().setAps(Aps.builder().setContentAvailable(true).build()).build());
Is it possible to identify whether a particular push notification message was delivered to a particular token via Firebase Cloud Messaging? And, if so, is it possible to do so via an API call or by listening to some callback?
I know that I can look at aggregate statistics in the console and even segment those statistics through analytics tags, but cannot find a way to get more discrete information.
I also know that the API will synchronously respond if a token is invalid but the process by which Apple and Google invalidate tokens is a bit opaque (to me) and doesn't help if someone simply turned off push notifications for my app.
Thanks!

If someone turned off push notification – you can check it with code
Swift ios check if remote push notifications are enabled in ios9 and ios10
Android app - detect if app push notification is off
But user can be offline, or APNs / Firebase service – can get some problems and your notification will be drop. You can check delivery status with some code in iOS and Android applications.
If you need check, delivery status for some push you can make push notification extension (in iOS). For send status about delivered notification in your API. More info about push notification extension.

I hope this answer will help with your problem.

Received (available only on Android devices) — The data message or
notification message has been received by the app. This data is
available when the receiving Android device has FCM SDK 18.0.1 or
higher installed.
I have completed an e-commerce app in ionic3. The problem is I want user to be notified when new offers or deals are added in our inventory. This should be a backend process, whether or not the app is open or close.
Note: There is no firebase involved.
If you want to use to get notification in same device then you can try Local notification native plugin for notification and if you want to send notification to other device then you have to use Push or FCM or Onesignal and yes this all required firebase to send push notification to generate device id/key.
I am sending push notifications using Flutter's firebase_messaging package and I send them in the firebase console. When the app is in the background or when it is closed, I am receiving the notifications, however, when the app is in the foreground it is not working. Please tell me if I need to integrate Javascript to make this feature work, and please reference a resource that I can use in order to figure out how I can integrate Javascript with fcm as I haven't found a way to do this with flutter.
I figured out that someone can use the flutter local notifications plugin so that when the push notification is sent and the app is on the foreground, normally no notification would be delivered to the system tray, but using the flutter local notifications plugin, it would be possible to send a local notification when the app is on the foreground.
To Understand better.
Have a look into this table.
https://pub.dev/packages/firebase_messaging#receiving-messages
It states that when your Android or iOS Application is in foreground, OnMessage callback is called if you are sending notification payload or data payload as notification body.
You are receiving notifications when your app is in background because, when an app is in background notification is send to system tray and OS (Android or iOS) handle it for you. And your app is launched when you click on notification from system tray.
When your app is in foreground you have to catch notification payload in onMessage and handle it explicitly, you can create local notification in this case.
