Single Codebase, Dual Platform Release
We build one Dart codebase that compiles to native iOS and Android binaries, cutting duplicate logic and keeping feature parity automatic instead of something your team has to chase manually.

01
Start with context
The work, in plain language
A clear view of the problem before we shape the solution.
Quinoid's Flutter development team builds apps from a single Dart codebase that ships to iOS, Android, and web without maintaining three separate engineering tracks. Flutter's widget-based rendering engine draws every pixel itself rather than relying on platform UI components, which means the app looks and behaves identically on an iPhone and a budget Android device — a real advantage for teams shipping cross-platform mobile apps efficiently and consistently. We use Flutter where the product calls for fast iteration and shared business logic across platforms, and we're equally direct about where it doesn't fit — apps leaning heavily on cutting-edge native APIs sometimes still need a native build. For most consumer and B2B products, though, a single codebase means feature parity by default: there's no scenario where the Android app ships a fix three sprints before iOS catches up. Our India-based engineers have shipped Flutter apps through both the Play Store and App Store review processes, handling the platform-specific packaging each store requires even though the underlying code stays shared. That single-codebase model typically cuts both development time and ongoing maintenance cost compared to building native iOS and Android apps separately.
We ask the practical questions early, involve the people who use the product, and keep the work visible as it develops.
What we can help you deliver
Focused help, shaped around the part of the journey you are in.
Custom Widget & Animation Development
Flutter's rendering engine lets us build pixel-precise custom UI and animations that look identical across devices, rather than being limited to each platform's default component styling.
Native Plugin Bridging
When a feature needs true native access — a specific camera API or background sensor — we write platform channels to bridge into native iOS/Android code without abandoning the shared codebase.
Dual Store Release Management
We package and submit the same Flutter codebase separately for Play Store and App Store review, handling each platform's distinct submission requirements while keeping one source of truth for the app logic.
How the work moves
Small, visible steps keep decisions timely and surprises rare.
Codebase Architecture Planning
We design the state management approach (Bloc, Riverpod, or Provider) and folder structure upfront, since a disorganized Flutter codebase becomes hard to maintain once a team scales features.
Shared UI Component Build
We build the widget library and design system first, so every screen after that reuses consistent, tested components instead of one-off layouts.
Feature Development in Sprints
Engineers build features in Dart across two-week sprints, testing each on both an iOS simulator and an Android emulator before calling it done.
Native Bridge Implementation
Where a feature needs native-only access, we write the platform channel and verify it works identically when called from both platform builds.
Dual-Platform QA & Store Submission
We test on real iOS and Android devices side by side, then submit separately to App Store Connect and Play Console since each store reviews independently despite the shared code.
What better looks like
A cross-platform app with lower duplicated development effort
Consistent experiences across iOS and Android
A faster route from prototype to production release
05 / Why Quinoid
Experienced enough to guide. Close enough to care.
Flutter promises one codebase for two platforms, but only if it's architected correctly from the start. Quinoid's Flutter engineers structure state management and native bridging upfront, so the time savings show up at delivery — not get eaten by rework later.
- 01
We've shipped Flutter apps through both Play Store and App Store review, so platform-specific submission quirks don't surprise us mid-launch.
- 02
Our state management architecture (Bloc/Riverpod) is set before feature work starts, avoiding the messy widget trees that make many Flutter apps hard to maintain later.
- 03
We write native platform channels when a feature genuinely needs them, instead of forcing every requirement through Flutter plugins that may lag behind OS updates.
Proof in Production
Not a claim or a concept. Work that made it into people’s hands.
Questions people usually ask us.
Is Flutter as fast as native iOS and Android apps?
For most consumer and B2B apps, yes — Flutter compiles to native ARM code and renders its own UI layer, so performance is close to native. Extremely graphics-intensive apps may still benefit from a fully native build.
Can a Flutter app access native device features?
Yes, through platform channels that bridge into native iOS/Android code for features without a mature Flutter plugin. We write these bridges directly rather than relying on unmaintained third-party packages.
Does Flutter reduce development cost compared to building two native apps?
Generally yes — a shared codebase means most feature work happens once instead of twice. The savings are most significant on UI-heavy apps with shared business logic across platforms.
Do Flutter apps still need separate App Store and Play Store submissions?
Yes — each store reviews and packages independently regardless of shared code underneath. We manage both submission processes so the single-codebase advantage doesn't get lost at release time.
