Flutter App Development
One Flutter codebase for iOS and Android, with smooth performance and a polished interface on both platforms.
Why build your app with Flutter?
Flutter is Google's open-source framework for building apps from a single codebase. It draws its own interface, which gives consistent designs and smooth animations on iOS and Android, and it can also target web and desktop.
For most business apps, that means lower costs and faster releases than building two separate native apps, with one team fixing bugs and shipping features for both platforms at once.
Maetheon Ltd builds Flutter apps for startups and businesses in the UK, the US, Canada and Australia. We handle design, development, backend, testing and store submission, as a UK-registered company with a remote development team.

Planning a Flutter project
State management and structure
We choose a clear architecture and state-management approach from the start, so the app stays easy to change as features grow and new developers join.
Platform details still matter
A single codebase doesn't mean ignoring platform differences. We handle permissions, notifications, payments and store requirements separately for iOS and Android where they differ.
Automated builds
CI/CD pipelines build, test and distribute the app to testers automatically, which speeds up feedback and makes store releases routine.
