The Flutter Firebase Compendium Demo Application

This is the companion app of the Flutter Firebase Compendium with code examples.

The Flutter Firebase Compendium is an article series published on Medium. It explains how to use Firebase services from a Flutter application.

I recommend buying my ebook. It contains a lot more details and will save you many hours of research time to develop your apps quicker.

How to run the code

The code uses Firebase as a backend but the Firebase configuration is not included. You have to add it yourself because there are paid features that might cause costs. Refer to this article above on how to perform the necessary steps in detail.

1. Create a Firebase project
2. Install Firebase CLI
3. Install FlutterFire CLI
4. Check out the code
5. Execute firebase login from the app root folder and log into your created Firebase project
6. Execute flutterfire configure from the app root folder and use your created Firebase project
7. A file firebase_options.dart will be created in your lib folder
8. (Cloud Functions only) Execute firebase deploy --only functions to deploy the demo functions
9. (Storage and Cloud Firestore only) Set security rules for Storage and Firestore
10. (App Check only) Register an attestation provider and enforce App Check
11. (Remote Config only) Create parameters with conditions for Remote Config
12. Run the app

Hints

• 💡 Social sign-in only works on web platform
• 💡 You need to replace the link on functions_page.dart according to your deployed function link!
• 💡 Don't forget to set the security rules for Storage and Firestore!
• 💡 To get file downloads from Firebase Storage work on the web platform, you need to set specific CORS rules!
• 💡 The Play Integrity attestation provider is not working at the moment. Use SafetyNet as replacement! => SafetyNet deprecated, supported until June 2024!)
