App Development with Flutter

Cross-platform apps for iOS and Android from a single codebase — fast, native-performance, and maintainable.

Native Performance, One Codebase

With Flutter we develop cross-platform apps that feel native on iOS and Android — from a single Dart codebase. The result: shorter development times, consistent UX on all platforms and significantly lower maintenance costs.

Our Services at a Glance

  • Cross-Platform Apps: One codebase for iOS and Android with native performance thanks to Flutter's own rendering engine (Skia/Impeller).
  • UI/UX Design: Material Design and Cupertino widgets for platform-appropriate user interfaces, combined with individual custom widgets.
  • Backend Integration: Connection to REST APIs, GraphQL, Firebase, Supabase or existing Laravel backends — including offline sync and local data storage.
  • Maps & GPS: Integration of Google Maps, MapLibre and Geolocator for location-based features and real-time tracking.
  • Push Notifications: Firebase Cloud Messaging (FCM) and Apple Push Notification Service (APNs) for reliable notifications.
  • App Store Deployment: Full support for releases in the Apple App Store and Google Play Store including CI/CD pipeline.

Technology Stack

Our Flutter projects rely on Dart as the programming language, Flutter as the UI framework, Riverpod or BLoC for state management and Firebase or Laravel as the backend. For maps we use Google Maps and MapLibre, for multimedia Audio Player and PDF Viewer.

Our Approach

We start with a prototype and validate early. Thanks to Flutter's hot reload you see changes in real time. Automated tests at the widget, integration and end-to-end level ensure quality. Our CI/CD pipelines provide automatic builds and store deployments.

Frequently Asked Questions

With Flutter, we develop for iOS and Android simultaneously from a single codebase. This saves 30–40% of development time and cost compared to two separate native apps — with equivalent performance.
Yes. We seamlessly integrate Flutter apps with existing REST APIs, GraphQL endpoints, or Laravel backends. Integrations with Firebase, Supabase, or proprietary systems are also possible.
We guide you through the entire process: from concept development and UI/UX design through development and testing to release on the Apple App Store and Google Play Store.
Flutter apps achieve native performance because the framework renders directly to the GPU and does not communicate through a bridge like React Native. With AOT compilation, the app starts quickly and runs smoothly.
Of course. We offer long-term maintenance contracts that include regular updates for new OS versions, dependency updates, performance monitoring, and feature enhancements.
