Flutter app development for iOS and Android
Build or extend an iOS and Android app from one Dart codebase, with native integrations where the product needs them. I work from Barcelona with teams across Europe and the US, and can audit inherited Flutter projects before you commit to a rebuild.
What you get
- Product flows and interfaces implemented against the agreed scope and designs.
- Dart state and data handling connected to the APIs and services your app needs.
- Native bridges where a device capability calls for platform-specific code.
- Accessibility checks, relevant automated tests and device QA, with source code and handover materials in accounts you own.
How it works
- Set the platform plan Review the product, devices, existing code and native requirements, then agree what belongs in shared Flutter code and what needs a platform-specific path.
- Build the product slice Implement the agreed screens and data flows, integrate APIs and add native bridges where they serve a clear user need.
- Check and hand over Review accessibility and tests, exercise the app on agreed devices, and document the code and release setup for your team.
A good fit if
- You want an iOS and Android app and shared product logic suits its requirements.
- You have a Flutter app that needs new features, a technical review or a careful repair.
- You need native device integrations considered alongside a consistent cross-platform interface.
Share product logic while respecting each platform
Flutter lets an app share much of its interface and Dart logic, but device behavior still deserves deliberate design. We map the flows that can stay common and identify where accessibility, permissions, background behavior or a native API calls for platform-specific work.
- Agree the supported iOS and Android versions and the devices that matter to your users.
- Plan state, API access and error behavior as part of the product flow.
- Choose native bridges only for requirements that benefit from them.
Choose an approach with scope in view
Before implementation, compare Flutter with native development against the app's device features, interaction needs and team ownership. A useful estimate accounts for screens, backend work, integrations, accessibility and device QA, rather than counting screens alone.
- Use the calculator to outline a starting scope and discuss the assumptions together.
- Keep test and production services, credentials and release steps clear for the agreed setup.
- Hand over code and project access through accounts your organization owns.
FAQ
When should I choose Flutter over Swift or Kotlin?
Flutter can suit products that benefit from shared Dart code across iOS and Android. If the experience depends on deep platform-specific behavior, specialized native APIs or native-first performance, a Swift or Kotlin approach may fit better. We assess that before setting scope.
Can you work with an existing Flutter app?
Yes. I can review its structure, dependencies, data flows and release setup, then scope improvements or new features around the code that is already there.
How much will a Flutter app cost?
Cost depends on the product flows, integrations, device coverage and quality work in scope. Use the app cost calculator to frame an estimate, then see pricing and engagement options before agreeing the work.
Who owns the code, and how is it handed over?
Your project code stays in a repository you control, with agreed documentation and access handover. QA and production settings are kept distinct where the project scope requires them.
