Flutter is not the point. The wait is.

We build cross-platform mobile apps with Flutter for teams who need iOS and Android from one codebase: a dedicated Flutter development team, written scope, and IP in your accounts.

Nobody asks for Flutter by name. They ask why the app feels different on iOS and Android, or why every fix means changing two codebases instead of one.

What we build with Flutter


Flutter development for cross-platform mobile products.

We help founders and teams use Flutter where it shines: consumer and business apps that need native performance on iOS and Android from a single codebase, with sensible state management and clean integration with your backend.

  1. Consumer & business mobile apps

    iOS and Android apps from one Flutter codebase, so you ship and support one build instead of two.

  2. Migration from native iOS & Android

    Replacing two separate native codebases with one Flutter build, feature by feature, without a freeze.

  3. Field & operations apps

    Apps for delivery, inspection or field teams that need offline support and a native feel.

  4. E-commerce & booking apps

    Catalogue, checkout and booking flows that stay smooth on both platforms.

  5. Design systems in Flutter

    A typed widget library your team can extend without breaking the product.

  6. Performance rescue

    Slow, rebuild-heavy apps profiled and fixed: measured before and after.

How Flutter projects run here


A practical Flutter process, from audit to production.

We keep the Flutter process structured but lightweight, so we can deliver a working build in real time without surprising you on quality, timeline or budget.

  1. Audit & architecture

    We read the existing code or the requirements, then propose component structure, state strategy and routing.

    Week 1

  2. Widget & state design

    A typed widget library and predictable state: the decisions that stop a Flutter codebase rotting.

    Week 1–2

  3. Implementation & integration

    Build or refactor components, wire them to APIs, handle loading, error and empty states properly.

    Sprint by sprint

  4. Testing, hardening & rollout

    Automated tests on critical paths, accessibility and performance passes, then a staged release.

    Pre-launch

  5. Ongoing support & features

    A standing team continues to ship features and keeps dependencies current.

    Post-launch

Where Flutter earns its keep


Flutter use cases we most often deliver.

Most of our Flutter work is on mobile product surfaces: consumer and business apps, rather than brochure-ware landing pages.

  • Companion mobile apps

    The mobile counterpart to a web product: onboarding, notifications and the flows people check daily.

  • Customer self-service apps

    Accounts, documents, invoices and requests, moved off email and spreadsheets onto a phone.

  • Field and delivery apps

    Offline-first apps for teams working outside an office, with sync once a connection returns.

  • Native-to-Flutter replacement

    Replacing two ageing native codebases with one Flutter build, screen by screen.

The stack around Flutter


The Flutter stack we typically use at QalbIT.

We usually pair Flutter with modern tooling: Dart with null safety, a typed widget library and a tested data layer, so the app stays maintainable and predictable as the team changes.

  • Core

    • Flutter (stable channel)
    • Dart
    • Material 3
    • Platform channels
  • State & data

    • Riverpod / Bloc
    • Dio
    • REST & GraphQL
    • Freezed
  • Styling & design systems

    • Material 3 theming
    • Custom widget libraries
    • Adaptive layouts
    • Design tokens
  • Quality & observability

    • flutter_test & integration_test
    • Very Good Analysis
    • Fastlane / Codemagic CI
    • Sentry & Firebase Crashlytics

We adapt to what you already run. If your team is on a different state library or design system, we work inside it rather than rewriting for preference.

Flutter in production


Where Flutter is the surface.

The same discipline on every build: typed widgets, predictable state, and the client owning the code.

Start here


Hire Flutter developers who will still be proud of the code in year three.

Share your current front end, goals and the problems you want to solve. We will review your requirements, look at any existing code and propose a practical Flutter plan that matches your stage and budget.

  • A written scope with the exclusions listed
  • An architecture recommendation for state and components
  • The name of the engineer who would lead it
  • Free, and yours to keep either way

Flutter development: frequently asked questions

Common questions about Dart, Flutter’s own rendering engine, cross-platform reach and team setup, plus what happens after launch.

Ask us directly →
When one codebase needs to reach further than phones: iOS, Android, and often web or desktop too, from the same Dart source. Flutter draws every pixel itself instead of handing off to native components, so the same screen looks and behaves identically everywhere it runs.
No. Dart is a typed, class-based language that reads close to Java, C# or TypeScript, so engineers with that background pick it up fast. We staff Flutter projects with engineers already fluent in it, so you are not paying for anyone’s learning curve.
Yes, but it takes deliberate work: the rendering engine will not automatically pick up iOS versus Material conventions for you, so we design and tune each platform’s look on purpose rather than relying on the OS to supply it.
Yes, and that is one of the reasons to pick Flutter specifically: one codebase for iOS, Android, web and desktop, with platform-specific adjustments where the experience should differ.
We write a small platform channel, a bridge to the native iOS or Android code for that one capability, and keep everything else in shared Dart.
Because Flutter renders every frame itself through its own graphics engine rather than delegating to native widgets, animations behave the same way across OS versions and devices instead of inheriting whatever quirks a given native component has that year.
Send us the goal and any existing code. You get a written scope, an architecture recommendation and a price range within 48 hours, free, and yours to keep either way.
