FlutterFlow + Supabase Integration Guide
FlutterFlow and Supabase together give you a native mobile app (iOS and Android) backed by a production-grade PostgreSQL database. FlutterFlow's visual builder handles the UI and app logic, while Supabase provides auth, real-time data, file storage, and edge functions — the full backend stack without a server to manage.
Why FlutterFlow + Supabase?
FlutterFlow has a native Supabase integration that auto-generates queries from your database schema. This means you can build full CRUD mobile apps in FlutterFlow with Supabase as the backend in a fraction of the time it takes to write Flutter code manually. Supabase's row-level security ensures your app is secure, and its real-time subscriptions enable live-updating feeds and notifications in FlutterFlow without extra complexity.
Setting up the integration
In FlutterFlow, go to Settings → Supabase and enter your Supabase project URL and anon key. FlutterFlow will scan your database schema and generate typed query widgets. Enable RLS on all tables in Supabase first. Create a FlutterFlow action on your login page that calls Supabase auth signIn — FlutterFlow stores the session token and includes it automatically in all subsequent Supabase queries.
Authentication flow
FlutterFlow's Supabase auth integration handles email/password, magic links, and OAuth (Google, Apple). The auth state persists across app restarts. For protected pages, FlutterFlow's authentication settings will redirect unauthenticated users to the login page automatically. User metadata (profile, role) is typically stored in a public.profiles table that mirrors the auth.users table via a trigger — FlutterFlow can query this for display purposes.
Real-world use cases
FlutterFlow + Supabase is the go-to stack for mobile consumer apps: social apps with feeds and likes, marketplace apps with listings and messaging, fitness apps with workout tracking, and task management tools. App Studio has shipped multiple FlutterFlow + Supabase apps to the App Store and Play Store — the combination produces native-quality apps without a full-time mobile development team.
Common pitfalls
Always set up RLS policies before connecting FlutterFlow — without them, any authenticated user can read all data. Use Supabase's policy editor to add per-user policies. Watch FlutterFlow's query patterns: loading a list page that runs a separate query per row will hit Supabase rate limits; use joined queries or views to batch data. Test on a real device early — FlutterFlow's preview mode doesn't always reflect production performance.
