Flutter App Development

One codebase for iOS, Android and web, with an identical interface everywhere.

Flutter is Google's framework for building an app for iOS, Android and, where it makes sense, web and desktop from a single codebase written in Dart. It is our default choice on projects where the design is distinctive and has to look exactly the same on both platforms.

What makes Flutter different is that it does not borrow the operating system's components. It draws every pixel with its own rendering engine, which means your brand guidelines get implemented without compromise or platform-specific workarounds.

Why the rendering engine matters

Frameworks that map onto system components are limited by what each platform allows. Flutter draws every button and every transition itself, so non-standard design work, unusual shapes, layered animation, custom charts, is implemented directly instead of being approximated, and it looks the same on iOS and Android. Animations stay smooth because Dart compiles to native machine code. This approach pays off most on products where the interface is a competitive advantage rather than a set of forms, and where a designer would otherwise be constrained by the default component library.

Dart, architecture and development speed

Dart is easy to pick up and strongly typed, which means fewer defects reaching production. During development, hot reload shows a change on the device in a couple of seconds without restarting the app, so polishing design and interaction is dramatically faster than the usual rebuild cycle. We structure projects in layers, separating interface, business logic and data, and manage state with Riverpod or BLoC depending on the scale. Business logic is covered by unit tests and the critical user journeys by integration tests, so refactoring stays safe.

From MVP to full product

Flutter is particularly strong for MVPs. If you need to validate an idea in the market with real users and real payments, a single codebase gets you there in 5–8 weeks for both platforms simultaneously. Importantly, that MVP is not throwaway work: the full product is built on the same codebase rather than restarted from zero. We wire in payments, subscriptions, push notifications, maps and analytics at the MVP stage already, so you have usable data from the first week after launch instead of guessing what to build next.

Backend, web and handover

We build backends on Laravel, or use Firebase with Firestore and Cloud Functions when a product needs real-time sync and the fastest possible start. If you also need a web surface, an admin panel or a partner portal, Flutter can produce it from the same codebase, which keeps one team on one project. At handover you receive the source code, design files, both published store listings, developer account access and a technical warranty for the period set in the contract covering any defect we introduced.

How we work

01

Brief and product scoping

We agree what belongs in the MVP and what moves to a later phase, then fix the timeline and price.

02

Custom design

We build a design system and prototype. Because Flutter renders its own interface, the designer is not limited to stock components.

03

Engineering in Dart

Two-week sprints, with a test build for both iOS and Android at the end of each one.

04

QA and release

We test on real devices, then publish to the App Store and Google Play with analytics and crash monitoring enabled.

ALL PROJECTS

Our guarantees

How we work and what you get

Transparent terms from the first call to launch: you see and check the finished product before the final payment.

  1. You pay after you check

    We hand over a fully working project. You test it, make sure everything meets your requirements, and only then pay. You choose how: the full amount after acceptance, in stages, or a partial prepayment with the rest after acceptance.

  2. Technologies written into the contract

    The programming languages, frameworks and versions for your website or app are stated in the contract before work starts, so you know exactly what you are getting.

  3. Launched and ready to use

    We install the project on your server, configure it to run securely and fast, connect your domain, and publish mobile apps on the App Store and Google Play.

  4. Technical documentation

    At handover you receive a document listing the languages, versions and technical specifications of your project, so you can verify the quality of the work.

  5. Video guide to your admin panel

    A video walkthrough of your admin panel in the language you prefer, so your team can easily manage the website or the app.

  6. Quality and free support after launch

    We follow international development standards, guarantee the quality and speed of the result, and support every project free of charge after launch, for the period set in the contract.

Frequently Asked Questions

How is Flutter different from React Native?

Flutter draws the interface with its own rendering engine, while React Native maps to the system's native components. Flutter is the better fit for distinctive custom design and rich animation; React Native is often better when your team already works in React and can maintain the app.

How long does a Flutter app take to build?

An MVP takes 5–8 weeks for both platforms at once, and a mid-complexity app 10–14 weeks. The single codebase shortens both development and QA, because each screen is written once and tested once rather than twice.

Do Flutter apps perform like native ones?

Dart compiles to native machine code, so there is no interpretation layer at runtime. Animations stay smooth on mid-range hardware too, which matters if a meaningful share of your users are on inexpensive devices rather than current flagships.

Can Flutter also give me a web version?

Yes, from the same codebase. That works well for admin panels and internal tools. For a public marketing site we usually still recommend a conventional website, because search engines index standard HTML pages far more reliably.

Will the design look identical on both platforms?

Yes, and that is one of Flutter's main advantages: your brand guidelines are implemented the same way everywhere. Where it helps users, we can still adapt specific elements, such as navigation or date pickers, to each platform's conventions.

Who owns the code and who maintains it?

The code is entirely yours, fixed in the contract. Flutter is a Google framework with a large developer community, so you can continue with another team at any point. We also offer a monthly support plan covering updates and new features.
