Question 1

How do I set up Firebase authentication in Flutter?

Accepted Answer

Add the firebase_auth plugin from pub.dev, then configure platform-specific files like Google Services for Android and iOS. Use Dart APIs to implement sign-in flows, such as email/password or social providers, following Firebase's Flutter documentation.

Question 2

Is FlutterFire production ready for iOS and Android?

Accepted Answer

Yes, the core plugins are stable for Android and iOS, as shown in the compatibility table with checkmarks. They are widely used in production apps with official support and regular updates from Google.

Question 3

FlutterFire vs Supabase for Flutter: which should I choose?

Accepted Answer

FlutterFire is best if you're committed to Firebase's ecosystem and need its specific services like Firestore. Supabase offers an open-source alternative with PostgreSQL, so choose based on backend preference, control needs, and pricing considerations.

Question 4

How to handle push notifications with FlutterFire?

Accepted Answer

Use the firebase_messaging plugin to integrate Firebase Cloud Messaging (FCM). Set up notification handlers in Dart code for foreground/background states and configure server-side sending via Firebase Console or Cloud Functions for targeted campaigns.

Question 5

Can I use FlutterFire for web apps without mobile?

Accepted Answer

Yes, most plugins support web, as indicated in the table. However, web setup requires adding Firebase configuration to your index.html file and may have limitations compared to mobile, so test thoroughly for web-specific use cases.

Question 6

What's the difference between FlutterFire and Firebase UI for Flutter?

Accepted Answer

FlutterFire provides core backend service integration, while Firebase UI offers pre-built UI components for features like authentication. They are separate projects; use FlutterFire for backend logic and Firebase UI to accelerate UI development with ready-made widgets.

Question 7

How to migrate from older FlutterFire versions?

Accepted Answer

Check the changelog and Firebase migration guides for breaking changes. Update plugin versions in pubspec.yaml, adjust code to new APIs, and test on all platforms, as updates can involve significant changes to initialization or method calls.
