Firebase Dart Admin Auth SDK

Overview

The Firebase Dart Admin Auth SDK offers a robust and flexible set of tools to perform authentication procedures within Dart or Flutter projects. This is a Dart implementation of Firebase admin authentication.

Features:

• User Management: Manage user accounts seamlessly with a suite of comprehensive user management functionalities.
• Custom Token Minting: Integrate Firebase authentication with your backend services by generating custom tokens.
• Generating Email Action Links: Perform authentication by creating and sending email action links to users emails for email verification, password reset, etc.
• ID Token verification: Verify ID tokens securely to ensure that application users are authenticated and authorised to use app.
• Managing SAML/OIDC Provider Configuration: Manage and configure SAML and ODIC providers to support authentication and simple sign-on solutions.

Getting Started

If you want to use the Firebase Dart Admin Auth SDK for implementing a Firebase authentication in your Flutter projects follow the instructions on how to set up the auth SDK.

• Ensure you have a Flutter or Dart (3.4.x) SDK installed in your system.
• Set up a Firebase project and service account.
• Set up a Flutter project.

Installation

For Flutter use:

flutter pub add firebase_dart_admin_auth_sdk

You can manually edit your pubspec.yaml file this:

dependencies:
  firebase_dart_admin_auth_sdk: ^0.0.1-pre+11

You can run a flutter pub get for Flutter respectively to complete installation.

NB: SDK version might vary.

Usage

Example:

import 'dart:io';
import 'package:bot_toast/bot_toast.dart';
import 'package:firebase/screens/splash_screen/splash_screen.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:firebase_dart_admin_auth_sdk/firebase_dart_admin_auth_sdk.dart';
import 'package:flutter/services.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  try {
    if (kIsWeb) {
      // Initialize for web
      debugPrint('Initializing Firebase for Web...');
      FirebaseApp.initializeAppWithEnvironmentVariables(
        apiKey: 'YOUR-API-KEY',
        projectId: 'YOUR-PROJECT-ID',
        bucketName: 'Your Bucket Name',
      );
      debugPrint('Firebase initialized for Web.');
    } else {
      if (Platform.isAndroid || Platform.isIOS) {
        debugPrint('Initializing Firebase for Mobile...');

        // Load the service account JSON
        String serviceAccountContent = await rootBundle.loadString(
          'assets/service_account.json',
        );
        debugPrint('Service account loaded.');

        // Initialize Firebase with the service account content
        await FirebaseApp.initializeAppWithServiceAccount(
          serviceAccountContent: serviceAccountContent,
        );
        debugPrint('Firebase initialized for Mobile.');
      }
    }

    // Access Firebase Auth instance
    final auth = FirebaseApp.instance.getAuth();
    debugPrint('Firebase Auth instance obtained.');

    runApp(const MyApp());
  } catch (e, stackTrace) {
    debugPrint('Error initializing Firebase: $e');
    debugPrint('StackTrace: $stackTrace');
  }
}

• Import the package into your Dart or Flutter project:

  import 'package:firebase_dart_admin_auth_sdk/firebase_dart_admin_auth_sdk.dart';
  

  For Flutter web initialize Firebase app as follows:

  FirebaseApp.initializeAppWithEnvironmentVariables(
    apiKey: 'YOUR-API-KEY',
    projectId: 'YOUR-PROJECT-ID',
    bucketName: 'Your Bucket Name',
  );
  

• For Flutter mobile:

  • Load the service account JSON

     String serviceAccountContent = await rootBundle.loadString(
       'assets/service_account.json',
     );
  

  • Initialize Flutter mobile with service account content

    await FirebaseApp.initializeAppWithServiceAccount(
      serviceAccountContent: serviceAccountContent,
    );
  

• Access Firebase Auth instance.

     final auth = FirebaseApp.instance.getAuth();
