Enhancing Push Notifications in Flutter  In the previous blog post , we covered the fundamental steps to integrate push notifications into a Flutter app using Firebase Cloud Messaging (FCM). In this continuation, we'll explore how to open a specific page when the user clicks on a notification, thereby enhancing the user experience and providing contextual information. Let's dive into the code changes required to handle notifications effectively: Updating firebase_api.dart import 'package:firebase_messaging/firebase_messaging.dart'; import 'package:pushnotification/Page/notification_screen.dart'; import 'package:pushnotification/main.dart'; class FirebaseApi { final _firebaseMessaging = FirebaseMessaging.instance; void handleMessage(RemoteMessage? message) { if (message == null) return; navigatorKey.currentState?.pushNamed(NotificationScreen.route, arguments: message); } Future<void> handleBackgroundMessage(RemoteMessage mes

  Introduction to MVVM Architecture MVVM (Model-View-ViewModel) is a software architectural pattern widely used in building user interfaces, particularly in frameworks like WPF, Xamarin, and Flutter. It's an evolution of the MVC (Model-View-Controller) pattern, aiming to improve separation of concerns and facilitate testability and maintainability of code. In MVVM, the UI is divided into three components: Model: Represents the data and business logic of the application. It encapsulates the data and operations that manipulate that data. The model notifies the ViewModel of any changes, but it's unaware of the UI. View: Represents the user interface. It's responsible for displaying data and capturing user input. Unlike MVC, the view in MVVM is passive and doesn't directly interact with the model. Instead, it binds to properties and commands exposed by the ViewModel. ViewModel: Acts as an intermediary between the view and the model. It exposes properties and commands tha
