Introduction

• Series Overview: Implementing Firebase features in a Flutter application.
• Objectives:
  • Set up Firebase manually and using CLI.
  • Implement email/password and phone authentication using Firebase.
  • Utilize Firebase Firestore and understand Firebase storage.
  • Understand and implement Firebase Cloud Messaging (FCM).

Setting Up Firebase

Requirements

• Gmail Account: Required to log into Firebase console.

Steps to Set Up Firebase

1. Create a Firebase Project:

   • Go to Firebase console.
   • Click on "Get started with Firebase project."
   • Accept terms and conditions.
   • Name the project (e.g., "login sign") and create it.
   • Firebase project creation confirmation.

2. Create a Flutter Project:

   • Open Android Studio.
   • Create a new Flutter project.
   • Assign a project name (e.g., "sign up loging").
   • Exclude platforms not needed (Linux, macOS, web, Windows).
   • Project creation confirmation.

3. Connect Firebase with Flutter:

   • Open Firebase console and select Android.
   • Retrieve package name from Android Studio:
     • Navigate to build.gradle in the Android folder.
   • Register app with the package name.
   • Download google-services.json and paste it into the app-level folder in the Flutter project.

4. Add Firebase Plugins:

   • Open android.build.gradle file.
   • Paste copied plugins from Firebase console.
   • Repeat for app-level build.gradle.

5. Initialize Firebase in Flutter:

   • Use flutter pub add firebase_core and flutter pub get.
   • In main.dart, initialize Firebase with: WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp();

6. Run the Application:

   • Connect device via USB.
   • Click run in Android Studio.
   • Confirm successful connection by running the app.
