Firebase notifications & awesome_notifications usage places & Cloud Messaging and more with http.post...

Where and how can I use Firebase Messaging & Http.post & awesome_notifications?

I opened this project to explain and give information about the notifications system I use in my own applications, if you pay attention to what I write and make the notification system, you will get a much more efficient and optimized notification system.

• To get tokens, you need to install the firebase_messaging package and get tokens from there.
• Example: await FirebaseMessaging.instance.getToken(),
• Note: this token must be the code of the person to be notified.
• You need to activate the Cloud Messaging API (Legacy and get it from the section that says Server key) from the firebase settings to the part that says FCM Key.
• My advice to you is to create a class called NotificationService, create a function called initialize in that class and call this function in main.dart.
• If you are going to use Cloud Messaging, you can initialize the awesome_notifications library inside this function.
• Then I suggest you to initialize the firebase_messaging library for foreground messages.
• When initializing for firebase_messaging, you can use the listen command to show a notification for incoming foreground messages (see: Flutter Snackbar but my recommendation isGetX - Snackbar).
• Then you need to prepare an event for foreground and background notifications, if you are going to use snackbar for foreground messages, you can put it in the onTap method.
• In addition, if the user you are sending a message to is already in the application.
• I recommend using the firebase database to ensure that it does not send messages. With the LifeCycle cycle, you can check the user's online or offline status and sendnotifications - accordingly.
• However, if you use LifeCycle, you may encounter some problems, for example, sometimes the user may appear online even when not in the application.
• This is a common situation in my applications and I recommend using Firebase Functions in this situation. You can enable the user to throw firebase data at certain intervals andto - integrate the status of being online or offline according to the incoming data with javascript codes.
