iOS & Android Apps.
One Codebase. No Compromise.
Flutter is Google's open-source UI toolkit for building natively compiled apps from a single Dart codebase. Unlike React Native which bridges to native components, Flutter renders its own UI via the Impeller rendering engine — delivering 60–120fps animations and pixel-perfect consistency across iOS and Android.
iCoderz has been building Flutter apps since the framework's 1.0 release. Our Dart engineers use BLoC architecture, Clean Architecture patterns, and Flutter's testing pyramid (unit, widget, integration). We've shipped Flutter apps for food delivery, fintech, healthcare, e-commerce, and enterprise across 12+ countries.
Senior Flutter engineers only (3–8 years, Google Developer Expert ecosystem). 100% Dart source code and IP ownership at handover.
Why We Recommend Flutter for Most Projects
Flutter hits the sweet spot between performance, UI fidelity, and development speed — making it the right choice for the majority of mobile app projects in 2026.
Flutter App Development Cost
Transparent estimates. Flutter is typically 20–30% cheaper than building separate native iOS and Android apps.
| App Type | What's Included | Timeline | Estimated Cost |
|---|---|---|---|
| Flutter MVP (iOS + Android) | Core screens + backend + App Store + Play Store | 10–14 weeks | $18K – $35K |
| Full-Featured Flutter App | Custom UI + Firebase + integrations + IAP | 14–20 weeks | $40K – $90K |
| Flutter + Web App | All above + Flutter Web responsive app | 18–26 weeks | $60K – $120K |
| Enterprise Flutter Platform | iOS + Android + Web + custom design system | 24–36 weeks | $100K+ |

iOS App
The Chowman App
The Chowman App opens the gateway for the world of flavorful Chinese cuisine for customers directly from the famous Kolkata-based Chinese restaurant chains.
iOS App
Square Fit
A fantastic mobile app that helps you make beautiful photo & video edits on a single app. Square Fit includes 50+ tools to edit, add effects, and optimize images and videos.
Experience in Every Sector
14+ years of building production-grade software across the most demanding industries.
Build A Flutter App Like Alibaba, Reflectly, or Hamilton
Alibaba’s Xianyu marketplace, Reflectly, and the Hamilton app all chose Flutter — because it delivers native-class UI with a single codebase. iCoderz has shipped 300+ Flutter apps that compete directly with native builds on performance, design polish, and feature depth.
Whether you are building a consumer marketplace, a SaaS mobile tool, or a high-frequency transactional app — Flutter lets us ship to both iOS and Android simultaneously without the cost of two native engineering teams.

Why Companies Choose iCoderz for Flutter
Expert Dart engineers, BLoC architecture mastery, dual App Store and Google Play submission, and Flutter experience across 20+ industries since the framework launched.
300+ Flutter Apps, iOS & Android
One codebase, two stores. We have shipped 300+ Flutter apps that look and perform identically on iOS and Android — without the performance compromises of older cross-platform approaches. Flutter is now our primary recommendation for most consumer app projects.
60fps Pixel-Perfect Performance
Flutter renders directly to a GPU canvas with its own rendering engine — no JavaScript bridge, no native widget wrapping. The result is 60/120fps animations and pixel-perfect UI that looks identical on every device.
30–40% Faster to Market Than Native
One codebase means one dev team, one sprint, one QA cycle. Flutter typically delivers iOS and Android simultaneously in 30–40% less time than building the same app natively twice — without sacrificing quality.
100% Code & IP Ownership
Full Flutter source code, pubspec, and NDA from day one. No lock-in, no recurring licensing. Your app is entirely yours at handover, including the full state management architecture and test suite.

Flutter and React Native are both production-ready frameworks. Flutter uses Dart and renders its own UI via the Impeller engine — delivering pixel-perfect consistency and 60–120fps animations without relying on native components. React Native bridges to native components and has a larger JS ecosystem. We recommend Flutter for most new projects in 2026 for its performance, UI consistency, and Google's continued investment.
A Flutter MVP for iOS and Android costs $18K–$35K — typically 20–30% less than building two separate native apps. A full-featured Flutter app with custom UI, Firebase, and integrations ranges $40K–$90K. We provide a detailed estimate after a free discovery call.
Major companies using Flutter in production include Google (Google Pay), BMW, eBay, Alibaba (Xianyu), Nubank, and thousands of startups globally. Google actively develops Flutter and uses it internally — which drives continued investment in performance, tooling, and the pub.dev ecosystem.
A basic Flutter MVP for iOS and Android takes 10–14 weeks. A full-featured app with custom widgets, Firebase, and backend integration takes 14–20 weeks. Complex enterprise Flutter apps take 22–30 weeks. This is typically 20–30% faster than building equivalent dual-platform native apps.
Yes — that's Flutter's core value proposition. A single Dart codebase compiles to native ARM code for both iOS and Android (and also web, macOS, Windows, and Linux). Both App Store and Google Play submissions are handled from one codebase, one team, and one release cycle.
Native apps (Swift for iOS, Kotlin for Android) offer maximum performance and deepest platform integration. Flutter shares one Dart codebase across platforms, delivering near-native performance at lower cost and faster timeline. We recommend Flutter for most new projects and native development when deep platform integration (AR, complex graphics, OS-level features) demands it.
You own 100% of the Dart source code, assets, and IP at project handover. We provide full code documentation, architecture diagrams, and deployment instructions for both App Store and Google Play. An NDA is signed before any project discussion begins.
