Flutter, Google's open-source UI software development toolkit, has gained immense popularity for building natively compiled applications for mobile, web, and desktop from a single codebase. When it comes to distributing your Flutter app, Firebase, another powerful platform from Google, offers a seamless solution for hosting, authentication, and various other features. In this guide, we will walk you through the process of distributing your Flutter app using Firebase.
Prerequisites:
- A Flutter app ready for distribution.
- A Firebase account (https://firebase.google.com/) with a project created.
Step 1: Set up Firebase in Your Flutter Project
Firstly, you need to connect your Flutter project with Firebase. To do this, add the Firebase SDK to your Flutter app by following these steps:
a. Open your Flutter project in an IDE (such as Visual Studio Code or Android Studio).
b. Navigate to your project's root directory and open the pubspec.yaml file.
c. Add the Firebase dependencies under dependencies:
dependencies:
firebase_core: ^1.10.6
firebase_auth: ^4.6.0
d. Save the file and run flutter pub get in your terminal to install the dependencies.
e. Import the necessary packages in your Dart code:
import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_auth/firebase_auth.dart';
f. Initialize Firebase in your main.dart file:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
Step 2: Configure Firebase for Distribution
Now that your Flutter project is linked to Firebase, configure Firebase for distribution:
a. Go to the Firebase Console (https://console.firebase.google.com/).
b. Select your project or create a new one.
c. In the left-hand menu, click on "Authentication" and set up the authentication method for your app (e.g., email/password, Google Sign-In).
Step 3: Prepare Your Flutter App for Distribution
Before distributing your app, you need to configure it properly. Update your Android and iOS configurations:
a. Android Configuration:
i. Obtain your google-services.json file from the Firebase Console.
ii. Place the file in the android/app directory of your Flutter project.
b. iOS Configuration:
i. Obtain your GoogleService-Info.plist file from the Firebase Console.
ii. Place the file in the ios/Runner directory of your Flutter project.
Step 4: Build Your Flutter App
Before deploying to Firebase, build your Flutter app for release. Open a terminal and run:
flutter build apk --release # For Android
flutter build ios --release # For iOS
Step 5: Deploy to Firebase Hosting
Firebase Hosting allows you to deploy and host your Flutter web app effortlessly. Follow these steps:
a. Install the Firebase CLI:
npm install -g firebase-tools
b. Authenticate with Firebase:
firebase login
c. Navigate to your Flutter project's build directory:
cd build/web
d. Initialize Firebase Hosting:
firebase init
e. Follow the prompts to set up your hosting configuration.
f. Deploy your app:
firebase deploy
Congratulations! Your Flutter app is now distributed using Firebase Hosting.
