Deploy your Flutter app to Railway
Step-by-step deployment help for Flutter apps on Railway. We fix Flutter-specific deployment issues, configure Railway, and get your app live. From $19.
Flutter issues we fix before deploying
Common Flutter problems that affect Railway 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.
Railway deployment issues we check for
Common Railway problems that break Flutter apps in production.
Nixpacks detects the wrong build system
Monorepo projects or apps with multiple package managers confuse Nixpacks auto-detection, resulting in incorrect build commands and failed deployments.
Volume data lost on redeploy
AI-generated apps store uploaded files or SQLite databases on the filesystem without configuring Railway volumes, losing all data on each new deployment.
Private networking misconfigured between services
Internal service communication uses public URLs instead of Railway's private network (*.railway.internal), adding latency and exposing internal APIs publicly.
Health check endpoint missing
Railway restarts services that fail health checks. AI-generated servers often lack a /health endpoint, causing unnecessary restart loops.
