One app, two stores
A product that needs iOS and Android versions at the same time without paying for two separate native teams.

Hire Flutter developers who think past the first release
Flutter makes the first version of an app quick to build. What decides its cost later is architecture, state management and how well it handles each platform's rules. That's where we spend our attention.
What is Flutter?
When you hire Flutter developers, you get engineers who build apps for iOS, Android, web and desktop from a single codebase using Flutter, Google's open-source UI toolkit. Flutter apps are written in the Dart language and draw their own interface with a rendering engine rather than relying on each platform's native widgets, so screens look and behave the same everywhere. Platform features such as the camera, payments or Bluetooth are reached through plugins or small pieces of native Swift and Kotlin code.
When Flutter is the right call
Brand-heavy interfaces
Custom designs, animations and transitions that must look identical on every device rather than adopt platform styling.
Field and operations apps
Apps for sales reps, drivers or technicians that work offline and sync with an ERP such as Odoo when back online.
Extending a mobile team
An in-house team that needs Flutter capacity for a feature stream, a release push or a codebase audit.
When we recommend something else
- Apps built around deep platform features — home-screen widgets, watch apps, CarPlay or advanced AR — where much of the work ends up native anyway.
- A web product that needs search visibility — Flutter web suits app-like tools, not content that must rank; use Next.js or plain HTML.
- A team already productive in React and TypeScript — React Native lets them share skills and some code with the web front-end.
- A very simple app that mostly displays a website — a responsive web app or PWA may be cheaper to build and maintain.
What our Flutter developers build
Customer-facing mobile apps
Ordering, booking and account apps with authentication, push notifications, payments and analytics.
Offline-first business apps
Data capture, inventory, delivery and inspection apps with a local database and conflict-aware sync.
Companion apps for existing systems
Mobile front-ends for an Odoo, Laravel, Node.js or Python backend, reusing its API and permissions.
Codebase takeovers
Review and stabilization of an existing Flutter app: dependency upgrades, state cleanup, tests and a working release pipeline.
How we layer a Flutter app
L1
Presentation
Screens and widgets that only render state and send user intent, kept free of business rules.
L2
State management
Riverpod or Bloc holding app state, with each feature's logic testable without a device.
L3
Domain and repositories
Business rules and repository interfaces that hide whether data comes from the network or local storage.
L4
Data sources
API clients, a local database for offline use, secure storage for tokens and a sync queue for pending changes.
L5
Platform integration
Plugins and small native modules for camera, location, payments and notifications, isolated behind interfaces.
L6
Build and release
Flavors per environment, automated tests and signed builds delivered to TestFlight and Google Play tracks.
Ecosystem we work with
- Dart
- Riverpod
- Bloc
- go_router
- Dio
- Freezed
- Drift
- Firebase
- flutter_secure_storage
- Codemagic
- Fastlane
- Sentry
Smooth, secure and easy to hand over
Smooth rendering
Widget rebuilds kept narrow, heavy work moved off the UI thread with isolates, and frames profiled in DevTools.
Secure by default
Tokens in the platform keychain or keystore, TLS for every request, and no secrets compiled into the app.
Accessible apps
Semantic labels, scalable text and sufficient touch-target sizes so screen readers and large-font users are supported.
Maintainable codebase
Feature-based structure, generated immutable models, and unit, widget and integration tests that run in CI.
Flutter, React Native or native?
| Criterion | Flutter | React Native | Native (Swift / Kotlin) |
|---|---|---|---|
| Language | Dart | JavaScript / TypeScript | Swift for iOS, Kotlin for Android |
| How UI is drawn | Its own rendering engine; identical on every platform | Real platform components driven from JavaScript | Platform components directly |
| Code shared across iOS and Android | Most of it | Most of it | Little; two codebases |
| Access to new OS features | Through plugins, sometimes after a delay | Through modules, sometimes after a delay | Immediately |
| Best fit | Custom-designed apps on several platforms | Teams with React skills or web code to share | Platform-specific, performance-critical apps |

Flutter questions
Why hire Flutter developers instead of separate iOS and Android teams?
Because one Flutter team can build and maintain both apps from a single codebase, which usually means fewer people to coordinate and features that ship on both platforms together. Separate native teams make more sense when the app depends heavily on platform-specific features.
Can you take over an existing Flutter app?
Yes. We start by reviewing the codebase, dependencies, state management, test coverage and build setup, then agree on what to stabilize first before adding features. If the original developers are available, a short handover helps a great deal.
Can you work alongside our in-house developers?
Yes. We can work in your repository, follow your code review process and conventions, and take ownership of agreed features or a part of the app. The scope and working arrangement are agreed at the start of each engagement.
Is Flutter good for apps that need to work offline?
Yes. Flutter apps can store data in a local database such as SQLite through Drift, queue changes while offline and sync them when a connection returns. The hard part is the sync and conflict rules, which have to be designed with the backend.
Does Flutter work for web and desktop too?
Flutter can build web, Windows, macOS and Linux apps from the same code. It suits internal tools and app-like experiences on those platforms, but for public websites that need fast first loads and search visibility, HTML-based frameworks remain the better choice.
