# Migrate From FlutterFlow to a Production Flutter Codebase You Own DreamLabs is an AI-powered app development agency in California — a fractional product team for mobile and web apps, from strategy to launch. For teams whose FlutterFlow app has real users and a roadmap the editor is slowing down. DreamLabs rebuilds it as a production Flutter codebase in your own repository, on the Firebase or Supabase backend you already run, so users keep their accounts and simply get an app update. It starts with a $4,000 two-week strategy sprint, and most builds take about 6 weeks after it. By John Krueger and Tomás Quiñonez-Riegos. Updated October 8, 2026. ## Frequently asked questions ### Does FlutterFlow export real Flutter code? Can't we just use that? Yes. Paid plans from Basic up include Code Download, and Growth and up can push to GitHub. The export is structured for the editor, with a model file per page and one global FFAppState, so we port your custom Dart and refactor or rebuild the structure around it. ### How much does it cost to migrate from FlutterFlow? Every migration starts with a two-week strategy sprint for a flat $4,000, refunded in full if we don't move forward together. We map your current app into a features table and scope the rebuild, and we quote the build from that scope. The price is set and approved at the end of the sprint, and that's what you pay. A FlutterFlow migration can cost less than building the same app new, because the product decisions, backend and designs already exist, and with our AI-accelerated process a build typically costs a fraction of what a traditional agency charges. ### How long does a FlutterFlow migration take? Two weeks for the sprint, then about 6 weeks for most builds, versus the roughly 6 months a traditional rebuild takes. Your FlutterFlow app is a complete, running specification, so engineers spend their time building rather than deciding. For a sense of pace on this stack, Grove went from idea to both app stores in six weeks. ### Will our users lose their accounts or data? No. In a FlutterFlow app, users and data live in Firebase or Supabase, outside FlutterFlow, and the rebuilt app connects to the same backend, so accounts, passwords and data are untouched. We release under your existing bundle ID and package name, signed with your keys: App Store Connect doesn't let a bundle ID change once a build is uploaded, and Android installs an update only when its signing certificate matches. If the Android upload key is lost, Play App Signing lets you request an upload key reset without changing the app's signing key. ### Should we migrate to Flutter or React Native? Flutter, almost always. Your FlutterFlow app is already Flutter underneath, so staying in the ecosystem preserves the most: custom Dart ports directly, and the app's exact behavior is easiest to reproduce. Moving to React Native means rebuilding every screen in a new language, which only makes sense in unusual cases, like a team already deep in JavaScript. If that's you, raise it in the sprint and we'll give you an honest recommendation. ## Your FlutterFlow app proved itself. Now make it yours. Building on FlutterFlow was a good call. It generates real Flutter code, paid plans let you download the whole project, and it put your product in front of users without an engineering team. That's the hard part done. We know this first-hand. We used to build apps in FlutterFlow, then switched to AI-accelerated development in Flutter, and we have exported most of the apps we started in FlutterFlow. The next stage asks for things an editor was not built to hand you. FlutterFlow pushes code to GitHub one way: its docs say it always pushes to a branch named flutterflow, and that direct changes there are overwritten by the next push. Its VS Code extension syncs custom actions, widgets, functions and dependencies back into the project on Growth plans and up, but pages built in the visual editor change only in the editor. The generated project gives each page a widget file and a model file and keeps app-wide state in a generated FFAppState class: workable inside FlutterFlow, and harder for engineers who expect to own the architecture, the reviews and the tests. Teams usually move when a specific goal comes into view: hiring Flutter engineers who expect to work in the repository, passing a customer's or investor's security review, or a feature that keeps fighting the generated structure. That is the moment to own the code outright. ### When to stay on FlutterFlow If one or two people build comfortably in the editor, releases go out on schedule and custom code is a small share of the app, stay. FlutterFlow is a productive way to run a product at that stage, and Code Download means you can still leave later without starting over. If that's where you are, we'll say so. Our [FlutterFlow vs Flutter](https://www.dreamlabs.pro/services/flutterflow-vs-flutter) guide sets out when to stay and when to move.

Collections, storage and Cloud Functions stay put, and because the rebuilt app reads the same data, nothing has to be migrated. - **Users keep their accounts.** Accounts live in Firebase Auth or Supabase Auth, not in FlutterFlow, so nobody re-registers or resets a password. - **Your custom Dart code ports over.** The custom actions, widgets and functions you wrote by hand move into the new codebase with light refactoring. - **Your screens become the spec.** Every page, flow and edge case is already defined by the running app. We rebuild them as reusable Flutter components with real state management and navigation. - **The generated code becomes a reference.** We read the exported project to confirm exact behavior, then replace per-page models and the global FFAppState with an architecture engineers can test. - **Your store listings stay yours.** We release under your existing bundle ID and package name, signed with your keys, so the rebuild reaches users as an update to the app they already have. - **FlutterFlow's backend wiring gets reviewed.** Any Firestore rules deployed from FlutterFlow's settings, any Cloud Functions it deployed, such as those behind push notifications, and the Editor access FlutterFlow was granted to your Firebase project are checked, replaced where needed, and removed at handoff. ## A Flutter codebase any engineer can grow You land on production **Flutter**: Dart with a proven state-management architecture, typed models, automated tests and CI/CD, connected to the Firebase or Supabase backend you already run. The app stays natively compiled for iOS and Android from one codebase, and Flutter builds for the web from that same codebase when your roadmap needs it. Flutter is the framework behind the apps we ship. [Grove](https://www.dreamlabs.pro/project/grove), a Flutter app on Firebase that moves real money through bank linking and ACH transfers, went from idea to both app stores in six weeks and had shipped 12 updates by version 1.4.2, built with Claude Code as part of our AI-accelerated workflow. [GlowCode](https://www.dreamlabs.pro/project/glowcode) shipped one Flutter codebase to the App Store and Google Play eight weeks from idea to launch. [Haikuists](https://www.dreamlabs.pro/project/haikuists) runs a Flutter mobile app for its poets and a Flutter desktop web app for its admins on one shared Firebase back end. No subscription sits between you and your app: you own a normal Git repository that any Flutter engineer can clone, run and extend. Already holding a code export? Our guide to [FlutterFlow exported code](https://www.dreamlabs.pro/services/flutterflow-exported-code) shows what's inside, what to keep and what to refactor. ## From strategy sprint to store update ### Strategy Sprint & Code Audit Two weeks, flat $4,000, refunded in full if we don't move forward together. We download your FlutterFlow project and map it against the running app into a features table: every screen, data binding, custom function, integration, database rule and Cloud Function. You get wireframes for anything that should change, an honest call on what refactors cleanly and what's faster to rebuild, and the first-release scope we quote the build from. ### Rebuild Into a Clean Codebase Senior engineers rebuild the app as a structured Flutter project with real state management, navigation and reusable components. AI speeds up the screen-by-screen work; engineers own the architecture and review every line. Custom Dart ports over, generated widget trees are re-implemented rather than patched, and the app talks to your existing backend from the start. ### Parallel Run & Cutover Because both versions use the same backend, we run the new build beside your FlutterFlow app against production data and check parity feature by feature: sign-in, payments, notifications, edge cases. Cutover is a normal store release under your existing bundle ID and package name, and users update the way they would for any new version. ### Launch & Handoff We ship through App Store and Google Play review, set up CI/CD and automated tests in your repository, remove FlutterFlow's access to your Firebase project, and hand over documentation a new Flutter hire can onboard from. Then you can cancel the FlutterFlow plan. ## Case studies - [Grove](https://www.dreamlabs.pro/project/grove.md): Climate fintech round-up app - [GlowCode](https://www.dreamlabs.pro/project/glowcode.md): Referral-based social app for beauty influencers - [Haikuists](https://www.dreamlabs.pro/project/haikuists.md): Private, native app for internal contractor management ## Free checklists - [Firestore and Cloud Storage Security Rules Checklist](https://www.dreamlabs.pro/services/firestore-security-rules-checklist.md): 24 checks, each with a test and its source. - [Supabase Row Level Security (RLS) Checklist](https://www.dreamlabs.pro/services/supabase-rls-checklist.md): 23 checks, each with a test and its source. ## Links - Full page: https://www.dreamlabs.pro/services/migrate-from-flutterflow - Offerings & pricing: https://www.dreamlabs.pro/offerings - Contact: https://www.dreamlabs.pro/contact
