Integrating Firebase with Flutter is a powerful combination that allows developers to build scalable and feature-rich cross-platform applications. Firebase provides a comprehensive suite of cloud-based tools and services, including real-time databases, authentication, cloud storage, and more. Here’s a deep dive into integrating Firebase with Flutter please see the below full tutorial:
Step 1: Set up a Flutter Project
Make sure you have Flutter installed on your system. Create a new Flutter project using the following command:
flutter create my_flutter_firebase_app
cd my_flutter_firebase_app
Step 2: Create a Firebase Project
login to your Firebase account and:
- Go to the Firebase Console.
- Click on “Add Project” and follow the setup instructions.
Step 3: Add Configuration in Flutter for Firebase
- Add the Firebase configuration files to your Flutter project:
- Download the
google-services.json
file for Android. - Download the
GoogleService-Info.plist
file for iOS.
- Download the
- Place these files in the respective directories:
- Android:
android/app/google-services.json
- iOS:
ios/Runner/GoogleService-Info.plist
- Android:
Step 4: Add Dependencies in Flutter Project
dependencies:
flutter:
sdk: flutter
firebase_core: ^1.10.6
firebase_auth: ^4.6.0
cloud_firestore: ^3.3.1
firebase_storage: ^10.6.0
Run flutter pub get
to fetch the dependencies.
Step 5: Initialize Firebase in Flutter
In your main.dart
file, initialize Firebase in the main()
method:
import 'package:flutter/material.dart';
import 'package:firebase_core/firebase_core.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
Firebase Services for Flutter:
Flutter provides huge list of service, few of them are below with examples.
Step 6: Authentication with Firebase
You can use Firebase for user authentication like Sign Up and Sign In with Email and Password.
import 'package:firebase_auth/firebase_auth.dart';
Future<void> signUp(String email, String password) async {
try {
await FirebaseAuth.instance.createUserWithEmailAndPassword(
email: email,
password: password,
);
} catch (e) {
print(e);
}
}
Future<void> signIn(String email, String password) async {
try {
await FirebaseAuth.instance.signInWithEmailAndPassword(
email: email,
password: password,
);
} catch (e) {
print(e);
}
}
Step 7: Cloud Firestore – Realtime Database
To use the real time data from Firebase, you use as below.
import 'package:cloud_firestore/cloud_firestore.dart';
Future<void> addDataToFirestore(String data) async {
try {
await FirebaseFirestore.instance.collection('collectionName').add({
'field': data,
});
} catch (e) {
print(e);
}
}
Step 8: Firebase Storage – Cloud Storage
To access the Firebase storage.
import 'package:firebase_storage/firebase_storage.dart';
import 'dart:io';
Future<void> uploadFile(File file) async {
try {
await FirebaseStorage.instance
.ref('uploads/file-name.jpg')
.putFile(file);
} catch (e) {
print(e);
}
}
Step 9: Use Firebase Services in Your Flutter App
Now you can use the Firebase services throughout your Flutter app. For example, display data from Firestore or authenticate users.
10 Real Time Users Analytics
You can track the real time users who are using your app with details data also.
This is a basic guide, and the actual implementation may vary based on your specific use case. Refer to the official documentation for more in-depth details and options: Firebase Documentation.
