Firebase Integration

June 02, 2026 • 1 min read

Firebase gives you a backend without writing servers: authentication, a realtime NoSQL database (Firestore), storage and push notifications.

Set up

  • Run flutterfire configure to link your Firebase project.
  • Initialise in main: await Firebase.initializeApp().
  • Add only the packages you need (firebase_auth, cloud_firestore, etc.).
// Firestore: read a collection live
StreamBuilder(
  stream: FirebaseFirestore.instance.collection('posts').snapshots(),
  builder: (ctx, snap) {
    if (!snap.hasData) return CircularProgressIndicator();
    final docs = snap.data!.docs;
    return ListView(children: docs.map((d) => Text(d['title'])).toList());
  },
)
Tip: Firestore streams update the UI in real time — great for chats and feeds.

Summary

Firebase provides auth, realtime Firestore data, storage and notifications, letting you ship full apps without your own server.
