Flutter App Development Agency

We build cross-platform iOS and Android applications with Flutter and Dart. One codebase, native performance, faster time-to-market — exactly what startups and businesses need to reach both platforms without doubling development costs.

Our Flutter development team in Ukraine delivers apps using Clean Architecture, BLoC state management, and thorough test coverage. We have shipped projects from initial MVP to products with thousands of active users.

What We Build

B2B and Enterprise Apps

Field worker tools, mobile CRM, inspection and audit apps. Role-based access control, offline sync, and integration with enterprise systems like ERP and third-party APIs.

Consumer Mobile Products

Marketplaces, social apps, health trackers, and fintech services. Animated UI, push notifications, OAuth flows, and payment integrations (Stripe, in-app purchases).

IoT and Hardware Integration

Apps that communicate with devices over BLE, Wi-Fi, or NFC. Real-time dashboards with telemetry feeds and sensor data streams.

AgriTech and MedTech Solutions

Data collection apps for regulated industries: offline-first operation, secure local storage, audit trail logging, and compliance-aware architecture.

MVPs and Rapid Prototypes

From concept to App Store and Google Play submission in 8–12 weeks. We help you validate your idea and get in front of real users fast.

Why Codevia

  • Ukrainian Talent, Global Standards

    Our team is based in Ukraine — you get senior-level Flutter development at competitive rates without compromising on quality. All developers go through rigorous technical evaluation.

  • Practical Time Zone Overlap

    UTC+2/UTC+3 gives a full working day with Europe plus 4+ hours of daily overlap with US East Coast and Canada — our afternoon is your morning. Daily standups, same-day responses, zero overnight lag.

  • Focused Specialization

    We focus on Flutter, .NET, and React. We do not try to do everything. That specialization means cleaner code, fewer bugs, and more predictable delivery.

Frequently Asked Questions

Flutter compiles to native ARM code and uses its own rendering engine (Skia/Impeller), which means pixel-perfect UI on both iOS and Android from a single codebase. For most business apps it delivers native-grade performance at significantly lower development cost than maintaining two native codebases.
We default to BLoC (Business Logic Component) for its strict separation of concerns and testability. For simpler apps or screens we use Riverpod. We avoid setState for anything beyond ephemeral widget state.
Yes. We integrate with REST, GraphQL, and gRPC backends. We handle JWT authentication, refresh token flows, file uploads, and WebSocket connections. If you don't have a backend yet, our .NET team can build one in parallel.
Yes. We implement local persistence with Hive or Drift (SQLite), queue operations when offline, and sync when connectivity is restored. We handle conflict resolution strategies based on your business rules.
We set up Fastlane pipelines for automated builds, code signing, and release uploads. We handle App Store Connect and Google Play Console configuration, including screenshot generation and metadata.
