Flutter Push Notifications ​(FCM) – ​Firebase Cloud Messaging Setup

In ‍today’s⁤ mobile development landscape, push notifications have become a vital feature for ⁤enhancing user engagement. Flutter, with its beautiful UI and cross-platform capabilities, makes sending push notifications through firebase Cloud Messaging (FCM) an easy task. This guide will walk you through the process of ‍setting up push notifications in your Flutter app using FCM.

What are push Notifications?

Push‌ notifications are messages sent​ by an request to a user’s device, even when the app is not ⁤actively running. They can serve various purposes,including:

• Informing users about updates or​ new content
• Engaging users through promotional messages
• Encouraging user retention and re-engagement

Why Use Firebase Cloud Messaging for Push Notifications?

Firebase Cloud Messaging (FCM) offers a robust and scalable solution for sending push notifications to your applications. Here⁤ are some advantages:

• Free: FCM ​is entirely free to use, allowing developers to send unlimited notifications at no cost.
• cross-Platform: You can send notifications‍ to Android, iOS, and even web applications‌ using the same service.
• Reliable delivery: FCM guarantees message delivery with high reliability⁢ and efficiency.

setting Up Firebase Cloud Messaging⁣ in Flutter

Step⁤ 1: Create a Firebase Project

1. Go ‌to the Firebase Console.
2. Click on “Add Project” ‍and follow the steps to create a new project.

Step 2: Add⁣ your Flutter‍ App to Firebase

1. Select your newly created ‍project.
2. Click on the “Add app” icon and choose the ⁢platform (iOS/android).
3. Follow the prompts to register your app by providing the necessary details such as your app’s package name.

Step 3: ‍Configure Your App

For Android:

1. Download the google-services.json file provided by Firebase.
2. Place this ‍file in the android/app directory of your Flutter project.
3. Modify the android/build.gradle file to include the Google services classpath:

    dependencies {

        classpath 'com.google.gms:google-services:4.3.10'

    }

    

4. In your android/app/build.gradle file, apply the plugin:

    apply plugin: 'com.google.gms.google-services'

    

For iOS:

1. Download the GoogleService-Info.plist file from the Firebase ⁤console.
2. Place this file into the ios/runner directory of your Flutter project.
3. Open the ios/Runner/Info.plist ‍ file and add the following permissions:

    UIBackgroundModes

    

        fetch

        remote-notification

    

    

Step 4: Add Dependencies in Flutter

Open your pubspec.yaml file and add the following dependencies:

dependencies:

  flutter:

    sdk: flutter

  firebase_core: latest_version

  firebase_messaging: latest_version

Replace latest_version ⁣ with the latest stable version of the‍ Flutter packages.

Step 5: Initialize Firebase in your ⁤app

In‍ your main.dart, initialize Firebase:

import 'package:firebase_core/firebase_core.dart';



void main() async {

  WidgetsFlutterBinding.ensureInitialized();

  await Firebase.initializeApp();

  runApp(MyApp());

}

Step 6: Set Up flutter Notification Handling

Now,set up Firebase Messaging ​to handle notifications:

import 'package:firebase_messaging/firebase_messaging.dart';



// Initialize Firebase Messaging

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging.instance;



// Request permission for iOS

_notificationSettings() async {

  NotificationSettings settings = await _firebaseMessaging.requestPermission();

}



// Listen for messages when the app is in the background

FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);



// Handler function

Future _firebaseMessagingBackgroundHandler(RemoteMessage message) async {

  // Handle your logic here

}

Testing​ Push Notifications

To test your push notifications,you can use the Firebase console:

1. Go to Cloud Messaging tab on⁣ the Firebase‍ Console.
2. Create a ‌new notification‌ and send it to your application.
3. Check your application to ensure that the notifications are being received.
