Masamune Auth Firebase

Overview

masamune_auth_firebase provides server-side integration utilities for Firebase Authentication in Masamune apps. This package focuses on backend operations that cannot be safely performed on the client side.

Note: This package does NOT include a client-side auth adapter. For Firebase Authentication adapters, see:

• katana_auth_firebase - Core Firebase Auth adapter
• masamune_auth_google_firebase - Google Sign-In with Firebase
• masamune_auth_apple_firebase - Apple Sign-In with Firebase
• masamune_auth_github_firebase - GitHub Sign-In with Firebase

Usage

Installation

Add the package to your project.

flutter pub add masamune_auth_firebase

Run flutter pub get after editing pubspec.yaml manually.

Delete User with Functions Action

This package provides FirebaseDeleteUserFunctionsAction for securely deleting Firebase Authentication users from your backend.

Client-side usage:

import 'package:masamune_functions/masamune_functions.dart';
import 'package:masamune_auth_firebase/masamune_auth_firebase.dart';

// In your controller or page
final functions = ref.app.functions();

Future<void> deleteUserAccount(String uid) async {
  try {
    final response = await functions.execute(
      FirebaseDeleteUserFunctionsAction(userId: uid),
    );
    // User deleted successfully
  } catch (e) {
    debugPrint("Failed to delete user: $e");
    rethrow;
  }
}

Server-side implementation:

Your Masamune Functions backend should handle the delete_user action:

// In your Cloud Functions or backend
if (action == "delete_user") {
  final userId = data["userId"];
  
  // Authenticate the request
  // Verify user has permission to delete this account
  
  // Delete using Firebase Admin SDK
  await admin.auth().deleteUser(userId);
  
  return {"success": true};
}

The action sends { "userId": uid } to your backend and expects an empty response (or throws an exception on failure).

Authentication Flow

For complete Firebase Authentication integration, combine with:

1. Core Auth: katana_auth_firebase for basic Firebase Auth
2. Sign-In Methods: Platform-specific packages like:
   • masamune_auth_google_firebase (Google Sign-In)
   • masamune_auth_apple_firebase (Apple Sign-In)
   • masamune_auth_github_firebase (GitHub Sign-In)
3. Server Operations: This package (masamune_auth_firebase) for secure backend operations
