How To Add Firebase To Your Flutter App?

# create a flutter app run this command
flutter create app_name --org com.YOUR_ORG_NAME

Step 2: Create a Firebase Console Account

Visit the Firebase Console and log in with your Google account. Optionally, create a new project with a unique name.

Step 3: Open Flutter Project in IDE

Open your Flutter project in your preferred IDE (e.g., VSCode).

Prerequisites

Make sure you have the following installed:

• Firebase CLI
• Flutterfire CLI

Already setup firebase and flutterfire cli then skips (1.0-2.0)

1. Install Firebase CLI

   # To follow the next Step you must npm or yarn installs your system. (install npm)
   npm install -g firebase-tools

   For Linux:

   curl -sL https://firebase.tools | bash

2. Configure Firebase CLI

   Log in to your account with Firebase CLI:

   firebase login

   It will open a new tab in chrome select the account and give the permission. If you successfully log in then flow to the next step.

3. Install Flutterfire CLI:

   dart pub global activate flutterfire_cli

Step 4: Initialize Firebase in Your App

Open your project in VSCode and navigate to the root directory. Run the following commands in the terminal:

1. From your Flutter project directory, run the following command to install the core plugin:

   flutter pub add firebase_core

2. Ensure your Flutter app's Firebase configuration is up-to-date

   flutterfire configure

3. In your lib/main.dart file, import the Firebase core plugin and the configuration file you generated earlier:

   import 'package:firebase_core/firebase_core.dart';
   import 'firebase_options.dart';

4. Also in your lib/main.dart file, initialize Firebase using the DefaultFirebaseOptions object exported by the configuration file:

   await Firebase.initializeApp(
     options: DefaultFirebaseOptions.currentPlatform,
   );

5. Rebuild your Flutter application:

   flutter run
