Why We Choose Flutter for Cross-Platform Apps
After shipping 5+ production apps across Flutter, React Native, and native — here’s why Flutter wins for most B2B product builds.
The decision framework
Every cross-platform project starts with the same question: Flutter or React Native? After delivering production apps in both — plus native Swift and Kotlin — we’ve settled on Flutter as our default for most B2B products. Not because it’s universally "better," but because of specific architectural advantages that compound over time.
Rendering consistency matters more than you think
Flutter owns its entire rendering pipeline — it doesn’t rely on platform UI components. This means a text field looks identical on a Pixel 6 and an iPhone 15. For B2B apps where dealers, agents, or technicians use a mix of cheap Android devices and premium iPhones, this eliminates an entire class of bugs.
React Native bridges to native UI components. That sounds good in theory — "native feel" — but in practice it means debugging platform-specific rendering differences for every custom component. We’ve spent weeks on RN projects fixing Android-only layout bugs that didn’t exist on iOS.
Dart is underrated for business logic
Dart’s sound null safety, sealed classes, and pattern matching make domain modelling a joy. When we model an order lifecycle (pending → accepted → dispatched → delivered → completed), the type system catches impossible states at compile time. TypeScript can approximate this, but Dart enforces it.
The monorepo advantage
With Melos (Dart’s monorepo tool), we structure large apps as 15-25 independent packages — shared domain models, feature modules, platform services, and UI components all versioned together. This scales to teams of 4-8 developers without merge conflicts destroying velocity.
When we DON’T choose Flutter
If the app is primarily a thin wrapper around web content (webview-heavy), we go React Native or PWA. If it needs deep platform integration (ARKit, HealthKit, Wear OS), we go native. If it’s web-only, we use React or Vue. Flutter isn’t a hammer — it’s a precision tool for the right jobs.
Our stack in practice
For a typical Flutter product build, our stack looks like: Flutter + BLoC (state management) + Drift (offline SQLite) + Dio (networking) + get_it (DI) + go_router (navigation). The backend is usually Firebase or AWS Lambda depending on the client’s existing infrastructure.
