On this tutorial, we’ll delve into the mixing of FCM in Flutter. We’ll discover its advantages and showcase real-world examples of the way it can improve consumer engagement and enhance app efficiency.
What’s Firebase Cloud Messaging?
Firebase Cloud Messaging (FCM) gives a dependable and battery-efficient connection between your server and gadgets. It permits you to ship and obtain messages and notifications on iOS, Android, and the online without charge.
On this tutorial, we’ll discover the method of establishing and utilizing Firebase Cloud Messaging (FCM) in Flutter utilizing Firebase because the backend service. Whereas the principle focus will likely be on Android implementation, it is price noting that the method is analogous for iOS and Android (with a number of configuration variations).
Here’s what we’ll cowl:
- How one can create an app in Firebase
- How one can arrange Firebase in Flutter
- How one can implement push notifications utilizing FCM tokens
On this tutorial, you will discover ways to ship a easy notification utilizing Firebase to the app operating in Flutter. Let’s get began.
How one can Create an App in Firebase
I am going to create a brand new challenge within the Firebase console to get began. I am going to stroll via the required steps, together with challenge setup, the best way to configure Firebase Cloud Messaging, and the best way to get the required credentials and configuration recordsdata for our Flutter app.
Earlier than creating the app it’s worthwhile to signup for the Firebase console if you do not have an account. After join, attempt to create a challenge.

After creating the challenge, it’s going to redirect you to the challenge dashboard.
Challenge Overview in Firebase Console
As soon as you have created the challenge in Firebase console, it is time to get began with our Flutter app.
How one can Set Up Firebase in Flutter
I’ve created a easy Flutter challenge utilizing Visible Studio Code. In case you are unfamiliar with constructing a Flutter challenge, you may consult with my previous tutorial. (In case you are already acquainted, you may skip this step.)
Easy Flutter Utility operating on Android Gadget
Let’s combine Firebase into our Flutter challenge. To do that, we want a Firebase CLI command line instrument. I’ve already put in the Firebase CLI. If you have not carried out this, you may consult with the official documentation.
Then we have to log in to Firebase utilizing Firebase CLI.
firebase login
Login to Firebase utilizing FirebaseCLI
This may navigate you to the browser to log in to Firebase. You may be navigated again as soon as the authentication is efficiently accomplished.
After profitable login, we have to set up FlutterFire CLI. We will use the FlutterFire CLI to configure our Flutter apps to hook up with Firebase. Run the next command to activate the FlutterFire CLI:
dart pub international activate flutterfire_cli
The FlutterFire CLI is a command-line interface instrument that simplifies the mixing of Firebase companies into Flutter functions. It gives a handy approach so as to add, configure, and handle Firebase plugins in our Flutter challenge.
Putting in FlutterFireCLI
The subsequent step is so as to add firebase_core library to our Flutter challenge.
The next command will mechanically add the firebase_core package deal as a dependency in your challenge’s pubspec.yaml file and fetch the newest model of the package deal from pub.dev. After operating this command, you may import the firebase_core package deal into the Dart recordsdata and use Firebase companies in our Flutter app.
flutter pub add firebase_core
Putting in Firebase Core package deal
The flutterfire configure command is used to configure Firebase companies in our Flutter challenge utilizing the FlutterFire CLI. This command helps us arrange Firebase authentication, Firestore, Cloud Messaging, and different Firebase companies simply and effectively.
flutterfire configure
Step one is to decide on the challenge,
Join Flutter App with Firebase app
The subsequent is to decide on the platform. I’m utilizing it for Android right here, so I select Android.
Selecting platform
After the profitable configuration, the Firebase App Id will likely be displayed.
Lastly, we have to add some code adjustments to our foremost.dart file.
Import the next packages:
import 'package deal:firebase_core/firebase_core.dart';
import 'firebase_options.dart';
Add the next configuration to initialize the Firebase config inside the principle operate of the foremost.dart file.
await Firebase.initializeApp(
choices: DefaultFirebaseOptions.currentPlatform,
);
Alright, now we have efficiently accomplished the Firebase configuration in our Flutter app! Let’s take a second to have fun this milestone. Configuring Firebase companies is a vital step in constructing highly effective and feature-rich functions.
How one can Implement Push Notification utilizing FCM Tokens
We’ll implement the method of registering gadgets for push notifications and retrieving the distinctive FCM tokens assigned to every system. This step is essential for sending focused notifications to particular gadgets.
We’ll dive into the implementation of sending push notifications to gadgets utilizing Firebase Cloud Messaging. We’ll discover the best way to construction and ship notification messages from the Firebase console and display the best way to deal with these messages inside our Flutter app.
flutter pub add firebase_messaging
Putting in firebse messaging Package deal
Subsequent, we have to set off the setAutoInitEnabled operate to allow automated initialization of Firebase Cloud Messaging (FCM) in our Flutter app. Which means that FCM will mechanically initialize and retrieve a tool token when the app begins.
Add the next operate name within the foremost technique:
import 'package deal:firebase_messaging/firebase_messaging.dart';
...
...
await FirebaseMessaging.occasion.setAutoInitEnabled(true);
Let’s run our Flutter app and confirm if we obtain the notification.
Navigate to the Firebase messaging console. As it’s our first message, we have to choose “Create your first marketing campaign”. Choose “Firebase Notification messages” and click on “Create”.
Pattern check messaging template
Now we have to enter the notification title, textual content, and title for the message.
Then we are able to get the FCM token manually for testing functions utilizing the code beneath. To retrieve the present registration token for an app occasion, name getToken() within the foremost() technique. This technique will ask the consumer for notification permissions if notification permission has not been granted. In any other case, it returns a token or rejects if there’s any error.
closing fcmToken = await FirebaseMessaging.occasion.getToken();
log("FCMToken $fcmToken");
Copy the FCM token printed on the console and paste it into the “Add an FCM registration token” enter field.
Despatched check message utilizing FCM Token
Click on on the Check button. The focused shopper system (with the app within the background) ought to obtain the notification.
Acquired push notification in android system
Hurray! We bought the notification on our Android system. If we click on on the notification it’s going to open the app by default.
After we faucet a notification, the default habits on each Android and iOS is to open the applying. If the applying is terminated, it will likely be began. Whether it is within the background, it will likely be dropped at the foreground.
Right here, we are able to see the fundamental configuration to initialize Firebase messaging.
foremost.dart
import 'package deal:flutter/materials.dart';
import 'package deal:firebase_core/firebase_core.dart';
import 'package deal:firebase_messaging/firebase_messaging.dart';
import 'firebase_options.dart';
void foremost() async {
runApp(const MyApp());
await Firebase.initializeApp(
choices: DefaultFirebaseOptions.currentPlatform,
);
closing fcmToken = await FirebaseMessaging.occasion.getToken();
await FirebaseMessaging.occasion.setAutoInitEnabled(true);
log("FCMToken $fcmToken");
}
Conclusion
On this tutorial now we have lined the important steps for implementing push notifications in Flutter utilizing Firebase Cloud Messaging (FCM).
By following the outlined steps, you may arrange Firebase, combine it into your Flutter challenge, and implement push notification performance.
