Flutter Firebase Authentication

This Flutter project demonstrates how to implement user authentication using Firebase. Firebase offers a powerful and secure way to manage user authentication in your Flutter apps. In this project, we'll walk you through the steps to set up Firebase Authentication, along with a basic Flutter app that allows users to sign up, sign in, and sign out.

Prerequisites

Before you begin, make sure you have the following installed:

• Flutter
• Firebase Account

Getting Started

1. Clone the repository

   git clone https://github.com/yourusername/flutter-firebase-authentication.git

2. Navigate to the project folder

   cd flutter-firebase-authentication

3. Install dependencies

   flutter pub get

4. Create a Firebase project

   • Visit the Firebase Console.
   • Click on "Add project" or select an existing project.

5. Set up your app in Firebase

   • Add an app to your project by clicking on the Android or iOS icon (whichever is applicable).
   • Follow the on-screen instructions to register your app with Firebase.

6. Add Firebase configuration files

   • Download the google-services.json file (for Android) or GoogleService-Info.plist file (for iOS) from the Firebase Console.
   • Place these files in the respective platform directories (android/app and ios/Runner).

7. Configure Firebase Authentication

   • In the Firebase Console, go to "Authentication" and enable the desired sign-in methods (e.g., Email/Password, Google, etc.).

8. Update Firebase configuration in your Flutter app

   • Open the lib/config/firebase_config.dart file.
   • Replace the apiKey, authDomain, projectId, storageBucket, and messagingSenderId with your Firebase project configuration.

9. Run the app

   flutter run

10. Sign up and Sign in

    • Open the app and create a new account or sign in using your email and password.

11. Sign out

    • You can sign out by clicking the "Sign Out" button.
