Native-Quality Cross-Platform Apps with Flutter

One codebase, two platforms, zero compromise on performance or polish. We've shipped Flutter apps to millions of users.

What is Flutter?

Flutter is Google's framework for building native iOS, Android, and web apps from a single Dart codebase. Used by BMW, Alibaba, and Google Pay. Unlike React Native, Flutter renders its own pixels — which means consistent UX across platforms and 60fps animations without hacks.

What We Build

Flutter projects we deliver

Consumer mobile apps

Social, marketplaces, fitness, content, on-demand — anywhere you need cross-platform polish without a dedicated iOS + Android team.

Complex animations and custom UI

Flutter's rendering engine makes fluid, custom interfaces tractable. We've built apps reviewers actually call 'beautiful'.

Offline-first apps

Field-service, logistics, and rural-connectivity apps with proper local databases (Drift / Isar) and conflict-free sync.

FlutterFlow → Flutter migrations

When you outgrow the visual builder, we migrate cleanly — same Dart code, no rewrites, full control.

Process

How we approach a project

  1. Discovery & architecture

    Pick state management (Riverpod / Bloc), navigation (go_router), and data layer up front. Future-you will thank us.

  2. Design system in Flutter

    Theming, components, typography — built once, reused across every screen.

  3. Feature sprints

    Two-week sprints with demos. Tested with widget + integration tests before merge.

  4. Performance & accessibility pass

    Profile on real low-end devices, fix jank, run accessibility audit before submission.

  5. Store launch & monitoring

    App Store, Play Store, plus crash reporting and analytics dashboards from day one.

Tech & Tools

What we use

Why DEVNIXS

Why pick us for Flutter

5+ years in production Flutter

We've shipped apps used by millions. We know every footgun and how to avoid it.

Test coverage is non-negotiable

Widget tests, integration tests, and golden tests. We refuse to ship Flutter code without them.

Native channels when needed

We write the iOS/Android platform code ourselves when a plugin doesn't exist or is unmaintained.

Performance-obsessed

We profile on a 4-year-old Android, not just an iPhone Pro. Apps feel fast everywhere or they don't ship.

FAQ

Common questions

  • Flutter vs React Native — what should I pick?

    Flutter for visual polish, complex animations, and consistency across platforms. React Native if you have an existing React/web team and need code sharing with web. Most agencies are biased — happy to give an honest read on yours.

  • Can Flutter do everything native can?

    Effectively yes. Camera, biometrics, payments, BLE, AR, push — all production-grade. The remaining 1% (extremely platform-specific UI) we wrap with native channels.

  • Do you build for web with Flutter too?

    Sometimes — Flutter Web is excellent for embedded app demos and internal dashboards but not the right tool for marketing sites. We'll recommend Next.js instead for those.

  • How do you handle CI/CD?

    Codemagic or GitHub Actions, configured to build and submit signed iOS + Android binaries on every merge to main.

  • Will my app feel native?

    Yes — we use Cupertino widgets on iOS and Material on Android by default, with platform-aware behaviours. Users can't tell.
