Flutter app development

Flutter is our core mobile technology. We have released dozens of Flutter apps — from fintech wallets and medical services to games and marketplaces. We know the framework inside out: custom animation, complex lists, offline mode, payments, maps, push and deep links.

We take on both new products and existing projects: code audits, refactoring, Flutter version upgrades, performance and stability work.

[ What's included ]

What we do with Flutter

Apps from scratch

Full cycle: architecture, UI, integrations, backend, publishing. One codebase — iOS and Android.

Audit and refactoring

We untangle inherited code, find bottlenecks, update dependencies and the Flutter version, remove crashes and memory leaks.

Custom UI and animation

Pixel-perfect Figma implementation, complex gestures and animations, tablet and foldable support.

Integrations

Stripe, Apple Pay, Google Pay, Firebase, maps, social login, video calls, Bluetooth devices and any REST/GraphQL API.

Backend for the app

Python + FastAPI + PostgreSQL, real-time via WebSocket, admin panel and analytics.

CI/CD and releases

Automated builds and delivery to TestFlight and Google Play, crash reporting, performance monitoring.

[ Process ]

How we work on Flutter projects

  1. Assessment

    For a new product — a consultation and spec. For an existing one — a free quick audit of the code and repository.

  2. Architecture

    We choose state management, module structure and a testing approach so the app stays easy to evolve.

  3. Development in sprints

    Every two weeks — a build on your phone via TestFlight and Google Play internal testing.

  4. Testing

    Unit and widget tests, manual QA on real iOS and Android devices.

  5. Release and support

    Publishing, updates for new OS and Flutter versions, feature development.

Minimum project budget
from $10,000

New Flutter projects start at $10,000. Audits and improvements of existing apps are estimated after a code review — usually from $3,000 per milestone. Payments are made per milestone, after the result is demonstrated.

[ FAQ ]

Flutter development FAQ

Why Flutter over React Native?

Flutter renders the UI itself, without bridges to native components, so it delivers a stable 60–120 FPS and an identical look on every device. It is backed by Google, the package ecosystem is mature, and the same code can target desktop and web.

Can you improve our existing Flutter app?

Yes — that's half of our requests. We start with a quick audit of architecture, dependencies, crashes and performance, then propose a plan from targeted fixes to a full refactor.

Can the app work offline?

Yes. We use local databases (Drift, Hive, Isar) and sync with the server when the connection returns — a typical scenario for field staff, delivery and healthcare.

How do you ensure code quality?

A single style and linters, code review, unit and widget tests for key logic, automated CI builds. The repository and documentation are handed over to you.

Is Flutter suitable for large products?

Yes — banks, marketplaces and services with millions of users run on Flutter. Our portfolio includes projects over $100,000, fintech and healthcare.
