I had a project from two application(flutter application) and three flutter-web on the same firebase i want to send notification from the web to the application.
i searched alot for this and i cant find any answer or solution for this case.

I hope you understand that we can't give you the finish solution here. I would recommend to you to go trough this docs.
What we can do is to explain it a little bit. For your solution I would recommend to use FCM. And how they work is that:
you use the Firebase SDK to receive a token from the client device.
you store that token on one of the Firebase databases
when sending a push notification to a device you would need to do it from the Firebase Cloud Functions and use that token to send the message to it. When you do that the device from witch the token is will get the message.
It doesn't matter what platform the device is (web, ios or android). All of them can receive Push Messages (in Web most of them but nor 100% all).
From your use case I would not recommend to use topics. You want to send messages from device to device and therefore the tokens are the best solution for it.
I have spent hours trying to find out anything about consuming browser notifications, but I literally couldn't find anything at all. Is there a way, from a CLI application, to subscribe to a service that pushes web notifications? I have looked into the browser API and everything, but I can't figure out or find any resources on how to, or whether it is possible to consume these notifications.
My goal is to write a Telegram bot that will subscribe to one of those services that pushes notifications, read the notifications, evaluate them and potentially message me.
The reason I want to do this is because the website does support sending me a certain amount of information, but I only want to be notified of some of that.
I'm thinking to work on firebase notifications in the last few days but I want to some answers for this few questions:
Does Ionic2 support firebase notifications ?
Will notification show in the top of screen when my application closed or it should be work in the background ?
Is firebase notification sent on time or it may take long time ?
If I assumed Ionic 2 can send private notifications (to my device only), so can I send public notification for all application users ?
If the answer of all questions "yes", wish you give me any useful links that may help me (if you have a time)
In addition to Gabriel's answer:
The default behavior for notifications is for it to show on the top part of the screen. I haven't worked on Ionic before, but AFAIK, the behavior should compared to Android.
With that said, you should refer to the Handling Messages part of the FCM docs.
There are factors to consider that may affect the time it takes for the device to receive a message, but as FCM's behavior, it would try it's best to send the message, as soon as feasible (see my answer here).
Gonna itemize this further:
Specific device only - Yup. When sending the message, just specify the registration token(s) that should recieve that message.
All devices - Yup. You could use the Firebase Notifications Console. But if you intend to send the message by using the REST API, you have to make sure that the devices are subscribed accordingly to your custom global topic.
About the device-to-device Gabriel mentioned, I think it should be worded as server to specific device(s).
Yes it does, and it works fine with FCM (Firebase Cloud Messaging, aka GCM - Google Cloud Messaging). It supports subscribing to topics and device-to-device notification via HTTP client. The topics subscriptions and device-to-device both require FCM plugin.
Yes, they'll appear on top of your device screen as any push notification, you'll just need to code how it'll behave after receiving it, like execute something if the notification is tapped, or do something if it's received and the app is already open (foreground), it's all up to you.
It's sent on time, i've never had delay problems, the longer it took to send the notification and i receive in my device was 10 seconds. But as far as i know it "stores" your notification for 24 hours, so if the servers go down or something happen the notification has a life time of 24 hours to be sent.
You can, as said in first answer, subscribe your users to topics. Let's say you want a topic to sent message so all users can receive, you can have an all topic, or have one only for logged users, one only for users who bought products, you can even get all users tokens and send one by one, but it's much better having them subscribe to topics.
Topics notifications can be sent via the Firebase project console. Device-to-device is sent by your app code.
To send device-to-device you'll need a token, it's provided by the FCM plugin (link above) and you'll need to store this token somewhere, like in your user node on Firebase. I usualy use the user device ID provided by the Device plugin to have his token, since the user can have multiple devices and log in all then, this'll prevent token overriding.
I don't know good tutorials about configuring FCM with Firebase, if i find something i'll edit the question and add it for you, but stick to the ionic native link and the FCM plugin github page.
Hope this helps.
I deployed a few apps which are used in several countries.
Now I'd like to send notifications but I can't found a way to send notifications in different languages.
My need is to send some news to the users, so it's not convainant for me to integrate translation into the i18n files.
I suppose i'm not the first to have this kind of question but I didn't found a lot of help on internet.
Please don't hesitate to share some tips or good practice about that
Thanks in advance,
Arnaud
APN and GCM themselves are only aware of the token for each device. It's Push Service Providers like Arrow Push that keep track of meta information on each token.
For Arrow Push you could create a separate channel for each language. Then when you send out a push notification you will need to do so for each language separately and target the related channel.
To subscribe a token/user to a channel see:
http://docs.appcelerator.com/platform/latest/#!/api/Modules.Cloud.PushNotifications-method-subscribeToken
To send to all tokens/users in a channel see:
http://docs.appcelerator.com/arrowdb/latest/#!/api/PushNotifications-method-notify
Or send via the Appcelerator Platform Dashboard.
I have developed an android application with the Parse push notification service and I can send notification from the Parse website.
How can I send push notifications through my own website using ASP.net? Is there any way?
I checked the Parse documentation but i get confused, I would really appreciate it if someone would help me.
Thanks
I ran into similar confusion. I wasn't even sure how to properly setup the user so that I could send a push notification directly to them. Then I found the following post:
Channels and Targeted Push Notifications
Note the last item under the Channels heading:
Most apps might find it useful to have a channel for each user so that
they can send messages to a user across all their devices and have
users follow others in the app.
So, now I know that I should subscribe each user to a channel that uniquely identifies the user (e.g., the 'bobsmith#foo.org' channel).
After I have subscribed the user to their channel, I can call Parse's REST API via my ASP.NET application. See Sending Pushes in the Parse REST API Developers Guide.
For an ASP.NET/C# example of how to submit a push notification check out this answer.
