Deploy your Flutter app to Vercel
Step-by-step deployment help for Flutter apps on Vercel. We fix Flutter-specific deployment issues, configure Vercel, and get your app live. From $19.
Flutter issues we fix before deploying
Common Flutter problems that affect Vercel 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.
Vercel deployment issues we check for
Common Vercel problems that break Flutter apps in production.
Serverless function size exceeds 50MB limit
AI tools bundle heavy dependencies into API routes without tree-shaking, pushing serverless functions past Vercel's 50MB compressed size limit and failing the build.
Edge runtime incompatible with Node.js APIs
Generated code uses fs, crypto, or other Node.js built-ins inside Edge Runtime routes, causing deployment failures since Edge only supports a subset of Web APIs.
ISR revalidation not triggering correctly
Incremental Static Regeneration configured with stale revalidate values or missing on-demand revalidation hooks, serving outdated content indefinitely.
Environment variables missing in production
Secrets added to .env.local but not configured in the Vercel dashboard, causing runtime crashes only in production while working perfectly in local dev.

Frequently asked questions
How do I deploy a Flutter app to Vercel?
We handle Flutter deployments to Vercel end to end. Start with our code audit ($19) to identify deployment blockers specific to your Flutter project, then we configure Vercel, fix issues, and get your app live in production.
What Flutter issues affect Vercel deployments?
Flutter projects commonly have api keys embedded in dart source code and inconsistent state management patterns. On Vercel, these combine with serverless function size exceeds 50mb limit and edge runtime incompatible with node.js apis to cause deployment failures.
Can SpringCode deploy my Flutter project to Vercel?
Yes. We specialize in deploying Flutter applications to Vercel. We audit your codebase for Flutter-specific issues, configure Vercel correctly, and handle the full deployment so your app runs reliably in production.
What does Flutter deployment to Vercel cost?
Our code audit ($19) identifies all Vercel deployment blockers in your Flutter project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
