# stack-flutter-firebase

**Layer 3 — Stack Composition**

Integration patterns for the most common Flutter fullstack combination:
Flutter + Firebase (Auth, Firestore, Cloud Functions, Storage) + Riverpod.

## Philosophy

Firebase documentation explains each service in isolation. Riverpod docs explain
state management in isolation. Neither explains: how Firebase Auth state feeds
into Riverpod providers, how Firestore streams compose with Riverpod's reactive
model, how to structure a project where Firebase is the backend and Riverpod
manages the entire state tree.

These seams are where this pack provides value.
