Flutter is the fastest way to ship a quality app on iOS and Android from one codebase. Our London Flutter team uses Dart 3, Riverpod, and modern null-safe architecture to ship MVPs in 12 weeks and consumer-grade apps in 20. Pixel-perfect on both platforms, single team, half the cost of native.
We start with a two-week discovery sprint — user flows, technical architecture, fixed-price scope. Every Flutter build uses our reference stack: Riverpod for state, Drift for local persistence, Firebase or Supabase for backend, and a CI/CD pipeline that ships TestFlight + Play Console builds on every merge.
For MVPs we ship a working app in 12 weeks: 5–8 screens, authentication, push notifications, payments, and analytics wired in. For consumer-grade apps we extend to 20 weeks with deep integrations, offline-first architecture, and platform-specific polish (Cupertino on iOS, Material 3 on Android).
Senior Flutter engineers only. No outsourcing, no juniors learning on your project. Every line of Dart is reviewed by a senior. You own all source code, signing certificates, App Store and Play Console accounts, and Firebase project from day one.
A typical engagement breaks down like this. Every line is in your fixed-price proposal — no day-rate ambiguity.
