Flutter app development

Some apps are a channel for an existing business. Others are the product itself, with a design language of their own and an experience that has to be identical on every screen it touches. Flutter is our framework of choice for the second kind.

Built by Google and compiled to native machine code, Flutter gives our engineers pixel-level control of the entire interface from one codebase that reaches iOS, Android, web and desktop. We build with it as part of complete digital estates, engineered by more than 30 specialists across our London, Oxford and Dhaka offices.

We've put Flutter into production too. See our TWoW! Flutter app case study to see how we rebuilt Toyota's employee engagement app with Flutter, Sanity and a headless architecture.

Why We Engineer With Flutter

Total Design Control

Flutter draws every pixel itself rather than borrowing the platform's widgets, which means your design system renders identically on every device, with no platform quietly overriding your brand.

The benefit: the design your team signed off is the design every user sees, everywhere.

Native Speed, Compiled

Flutter compiles to machine code, delivering the smooth animations and instant responsiveness users expect from the best native apps, even for graphically rich, motion-heavy interfaces.

The benefit: ambitious design without the performance tax that usually accompanies it.

OneCcodebase, Four Platforms

iOS, Android, web and desktop from a single codebase, with hot reload keeping iteration fast during development.

The benefit: every platform you add is an increment, not another team, and published market comparisons put cross-platform delivery at roughly 60 to 75% of the cost of building twice natively.

Maintained as Part of Your Estate

Our maintenance partnerships explicitly support Flutter apps: OS updates, SDK changes, releases and store submissions are handled under the same partnership that looks after the rest of your estate.

The benefit: the app keeps pace with Apple and Google without a separate support arrangement.

An Honest Note: When Flutter Isn't The Answer

If you already run a React or Next.js website, React Native usually wins on shared logic and cost, and it is the engine of our £60,000 website-and-app omnichannel starting point. If your app depends on the deepest platform capabilities, native development is the honest recommendation. Flutter's sweet spot is the standalone product where design fidelity across platforms matters most, and we will tell you which of the three fits on a discovery call, with reasons.

We’d love to hear about your website, app, or software needs.

Our discovery call is a straightforward chat to understand your goals and requirements. This allows us to provide a quote or arrange a technical follow-up to dive deeper into the architecture.
