Deploy your Flutter app to Supabase
Step-by-step deployment help for Flutter apps on Supabase. We fix Flutter-specific deployment issues, configure Supabase, and get your app live. From $19.
Flutter issues we fix before deploying
Common Flutter problems that affect Supabase deployments.
API keys embedded in Dart source code
Secret keys and API credentials hardcoded in Dart files. Since Flutter web apps compile to JavaScript, these keys are visible to anyone who opens browser dev tools.
Inconsistent state management patterns
AI tools mix setState, Provider, Riverpod, and BLoC in the same project. This makes the app confusing to maintain and introduces subtle state synchronization bugs.
Large initial download size for web
Flutter web apps ship a large main.dart.js file by default. Without deferred loading and tree-shaking, the initial page load can take several seconds on slower connections.
No input validation before API calls
Form data sent to backend APIs without client-side validation, leading to poor user experience (errors only appear after a network round trip) and unnecessary server load.
Supabase deployment issues we check for
Common Supabase problems that break Flutter apps in production.
Row Level Security disabled on tables
AI tools create tables without enabling RLS, allowing any user with the anon key to read, modify, or delete all data in those tables.
Service role key exposed in client-side code
The service_role key bypasses RLS entirely. AI tools sometimes embed it in frontend code instead of restricting it to server-side operations only.
Edge Functions hitting CPU time limits
Supabase Edge Functions have a 150ms CPU time limit on the free plan. AI-generated functions with heavy computation or unoptimized queries hit this limit under load.
Storage policies too permissive
Supabase Storage buckets created by AI have public access enabled or policies that allow any authenticated user to read all files, ignoring per-user access control.

Frequently asked questions
How do I deploy a Flutter app to Supabase?
We handle Flutter deployments to Supabase end to end. Start with our code audit ($19) to identify deployment blockers specific to your Flutter project, then we configure Supabase, fix issues, and get your app live in production.
What Flutter issues affect Supabase deployments?
Flutter projects commonly have api keys embedded in dart source code and inconsistent state management patterns. On Supabase, these combine with row level security disabled on tables and service role key exposed in client-side code to cause deployment failures.
Can SpringCode deploy my Flutter project to Supabase?
Yes. We specialize in deploying Flutter applications to Supabase. We audit your codebase for Flutter-specific issues, configure Supabase correctly, and handle the full deployment so your app runs reliably in production.
What does Flutter deployment to Supabase cost?
Our code audit ($19) identifies all Supabase deployment blockers in your Flutter project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
