I have initialized pusher_channels_flutter, and works.
How to watch pusher changes to send a push notification to watch changes in the background (when the app is closed).
The layout of the notification is minimalist, app logo + custom text from the pusher. For both mobile platforms!
Like:
Have a flutter_local_notifications possibly to send notifications in the background?
This is my first time doing this, I need some advice.
Have a nice day.

in my flutter project, I used FCM to push notifications and flutter_local_notification to display the received notifications
and I used the "data" payload to read the notification in my app.
and it works fine, but when I send more than one notification only the last one appears in the device tray (For both ios & android).
it seems like the application received only one notification
anything to do so multi notifications could be shown in the tray
I am trying to add the custom sound in the push notification. I have added the showNotification in the background handler on the client-side (flutter), but now when the application is in the background or terminated I receive duplicate notifications, one with default sound and the other with my custom sound. Can anyone tell me how to stop showing the default background notification?
You're getting the duplicate notification because
you're sending a notification message and it is automatically displayed by the FCM SDK and,
you're implementing a custom notification display yourself.
The solution is to send a data message instead of a notification message.
With FCM, you can send two types of messages to clients:
Notification messages, sometimes thought of as "display messages."
These are handled by the FCM SDK automatically.
Data messages, which
are handled by the client app.

I am trying to have my app execute functions in the background on a regular basis. As performFetchWithCompletionHandler is too unpredictable I read about APNs.
Can I use APNs to periodically send a silent push notification to the device that would make the app execute my data fetching and analyzing functions then displaying a notification to the user accordingly?
Is it possible to have the server send the "wakeup signal" only and have the app display the notification by itself because of this?
I might have misunderstood the APNs logic entirely.
I have an iOS 5 pager application.
Application can receive new message counter from server.
For example application received 5 as a response from server.
So no I need to create new (or update existing) notification in notification center panel
and additionally I need the notification center to receive these notifications while the application is in background.
Help me please. How can it be done?
All of the information you require is in Apple's iOS Developer docs: About Local Notifications and Push Notifications
You also might want to look into the introductory video from WWDC2011: Using local and push notifications on iOS and Mac OS X
I know you can register to have alerts or not when you call the push notification API. However my problem is that I want a certain class of actions to have an alert notification while no alert notification for other class of action?
So for example, an alert should be shown when we send the notification "Heart rate dropping alert!". But no alert should be shown when we send the notification "downloading updated patient data", the app should just take the notification as an instruction to being download if it is launched. And simply ignore it if it is not launched.
How to implement this?
Check Silent Push Notifications for iOS 7.In the WWDC 2013's "What's New with Multitasking" presentation, there is a section about Silent Push Notifications.
You can embed custom JSON data in the push notification, look at The Notification Payload in the Apple docs.
Update: I don't think that quite answers your question. You can send a blank notification that has the effect of cancelling any previous push notification (including those from other applications). I'm not sure if the app gets notified of that when it is actually running. If it does you might be able to do that in conjunction with a custom JSON payload to achieve what you want?
{"aps": {"badge": 0}}
You probably know this already - you can't use a push notification to launch the app on the iPhone without the user seeing a popup (apps can never run in the background on the iPhone).
However, you can display a different popup message and include different JSON data in the notification. Then if the user presses the button to launch the app ("Start", or whatever you call the button on the right) that JSON data is passed into the app. Your app can then carry out a different action based on that data.
Not possible. Push notifications cannot initiate tasks - nothing can cause an app to execute without user action. Similar question to Can I use Push Notification for this. You can trigger a sound, a text alert, or a badge value. That's it.
