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.
Consumer & business mobile apps
iOS and Android apps from one Flutter codebase, so you ship and support one build instead of two.
Migration from native iOS & Android
Replacing two separate native codebases with one Flutter build, feature by feature, without a freeze.
Field & operations apps
Apps for delivery, inspection or field teams that need offline support and a native feel.
E-commerce & booking apps
Catalogue, checkout and booking flows that stay smooth on both platforms.
Design systems in Flutter
A typed widget library your team can extend without breaking the product.
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.
Audit & architecture
We read the existing code or the requirements, then propose component structure, state strategy and routing.
Week 1
Widget & state design
A typed widget library and predictable state: the decisions that stop a Flutter codebase rotting.
Week 1–2
Implementation & integration
Build or refactor components, wire them to APIs, handle loading, error and empty states properly.
Sprint by sprint
Testing, hardening & rollout
Automated tests on critical paths, accessibility and performance passes, then a staged release.
Pre-launch
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.
