What is Flutter

One codebase. Two app stores.
Zero compromise.

Flutter is Google's open-source UI toolkit for building natively compiled apps for iOS, Android, web, and desktop from a single Dart codebase. Unlike frameworks that bridge to native components, Flutter uses its own Impeller rendering engine — giving you pixel-perfect, 60fps UI on every platform without compromise.

Dart compiles ahead-of-time to native ARM code, which means your app does not carry an interpreter at runtime. The result: startup times and scroll performance that match — and often beat — hand-written native apps.

Global team, local time zones

Offices in India, Australia, South Africa, and the UK mean we overlap with your working hours — no 3am calls.

Making the Right Choice

Flutter vs React Native
— an honest comparison

We build in both. Here's when we'd recommend Flutter over React Native, and when we wouldn't.

FactorFlutterReact Native
RenderingOwn engine (Impeller) — pixel-perfect on every platformBridges to native components — appearance varies by OS version
PerformanceCompiles to native ARM — 60fps with no bridge overheadJS bridge adds latency for complex UIs; improving but not at parity
UI consistencyIdentical pixels on iOS and Android — one design to QAPlatform widgets mean subtle differences; fine for many apps
LanguageDart — fast to learn, strictly typed, compiledJavaScript / TypeScript — huge talent pool, team re-use
EcosystemGrowing fast — pub.dev has 40k+ packagesLarger npm ecosystem, more third-party integrations
Desktop & webFirst-class targets — one codebase covers all platformsReact Native Web exists but is separate; desktop is limited
Best forAnimation-heavy UIs, design-driven apps, multi-platformTeams with JS expertise, deep native module access, existing React

Our recommendation: If you're starting fresh and design consistency or animation quality matters, choose Flutter. If your team already knows React and you have existing JavaScript infrastructure to reuse, React Native is the pragmatic choice. We'll tell you honestly which fits your situation — we're not paid by Google.

Our Process

How a Flutter
project runs

Five stages with clear deliverables at each step. Flutter's hot-reload shortens iteration loops — you see design changes in milliseconds, not recompile cycles.

01

Discovery & Flutter scoping

We assess whether Flutter is the right choice for your project, map your feature requirements, and define the state management architecture (Riverpod, Bloc, or Provider) before a line of code is written.

1–2 weeks
02

UI/UX design in Figma

Full app design using Material 3 or Cupertino design systems — including custom widget specs. You approve the Figma prototype before development begins.

2–3 weeks
03

Flutter development

Agile sprints with weekly demos via TestFlight and Play Console internal testing. You run the real app on your phone at every sprint review.

6–16 weeks depending on scope
04

QA & device testing

Flutter QA across real devices — not just simulators. We test on low-end Android hardware and multiple iOS versions, with performance profiling via Flutter DevTools.

1–2 weeks
05

App Store & Play Store launch

We handle both store submissions simultaneously — one of Flutter's biggest advantages. First-week traffic monitoring, crash reporting setup, and handoff to SLA maintenance if needed.

Common Questions

Frequently
asked

Still have questions? Contact us directly.

What is Flutter and why should I use it for my app?+
Flutter is Google's open-source UI toolkit for building natively compiled apps for iOS, Android, web, and desktop from a single Dart codebase. It uses its own rendering engine (Impeller), which means pixel-perfect UI on every platform without relying on platform widgets. If consistent design quality and fast cross-platform delivery matter, Flutter is usually the right choice.
Flutter vs React Native — which should I choose?+
Flutter gives better UI consistency and performance, while React Native has a larger ecosystem and JavaScript familiarity. We recommend Flutter when pixel-perfect design, animation-heavy UIs, or desktop/web targets matter. React Native when you have an existing JavaScript team or need deep native module access quickly. We build in both — we'll tell you honestly which fits your project.
How much does Flutter app development cost?+
A Flutter MVP typically costs $3,000–$8,000 covering both iOS and Android. A full cross-platform product with auth, payments, and admin dashboard runs $8,000–$20,000. Enterprise apps with complex integrations start from $50,000+. Flutter's single-codebase approach usually saves 30–40% compared to building separate native apps for each platform.
Can Flutter apps access device hardware like camera and GPS?+
Yes. Flutter has a rich plugin ecosystem (pub.dev) covering camera, GPS, biometrics, Bluetooth, push notifications, in-app purchases, and more. For anything not covered by an existing plugin, we write platform-specific channels in Swift or Kotlin that Flutter calls directly — giving you full native hardware access when needed.
How long does Flutter app development take?+
A Flutter MVP typically takes 8–14 weeks from discovery to launch. Because one codebase covers both iOS and Android — and both can be submitted to their stores simultaneously — Flutter projects run 20–30% faster than building two separate native apps for the same feature set.
Do Flutter apps perform as well as native apps?+
Yes. Flutter compiles to native ARM code and uses its own Impeller rendering engine — it doesn't bridge to platform widgets. In benchmarks and real-world use, Flutter apps match native performance for the vast majority of use cases. The only edge case is very deep OS-level integrations, where native still has a slight advantage.
