Definition

Why is Flutter different from React Native?

React Native uses a JavaScript → Native bridge. Every animation crosses the bridge. Flutter compiles to native ARM with AOT. No bridge. Skia renders directly to GPU. The result: consistent 60fps, not "mostly 60fps".

The trade-off: Flutter does not use platform native components. It draws everything with Skia. This guarantees perfect visual consistency between iOS and Android, but may feel "not native" to users expecting the exact iOS look. For most apps, consistency is an advantage.

Why

iOS, Android, Web, Desktop

One codebase, all platforms

Flutter is not "write once, debug everywhere". It is a single codebase that compiles to native AOT code. Skia renders every pixel identically on iOS, Android, Web and Desktop. Hot reload in 100ms for fast iteration. Widget tree optimized for consistent 60fps.

lib/widgets/product_card.dart
// Declarative UI with Hot Reload
class ProductCard extends StatelessWidget {
final Product product;
@override
Widget build(BuildContext ctx) {
return Card(
child: Text(product.name),
);
}
}
  • iOS+Android Platforms
  • 1 single Codebase
  • ✓ Hot Reload

Summary

For the CEO

The business value of Flutter.

One team, two native apps. Flutter enables simultaneous iOS and Android launch with the same code. This reduces development time by 40-50% compared to separate native teams.

Real native performance, not "almost native". Unlike hybrid solutions, Flutter compiles to ARM code. Your users will not notice it is not Swift or Kotlin. Ideal for apps requiring fluidity (fintech, e-commerce, social).

Google ecosystem with clear roadmap. Flutter is used by Google Ads, Google Pay, and companies like BMW, eBay, Alibaba. Not an experiment, it is enterprise production.

  • -40% Development time
  • 60fps Guaranteed
  • 95% Code shared

For the CTO

For the CTO

Flutter technical details.

AOT compilation to native ARM code. No JavaScript bridge, no interpretation overhead. Impeller engine replaces Skia on iOS for better Metal API performance. Profiling with integrated Flutter DevTools.

Clean Architecture + Riverpod for state management. Drift for type-safe local persistence (SQLite). Platform Channels when you need specific native APIs (Bluetooth, ARKit, NFC). Testing with Patrol for integration tests.

CI/CD with Codemagic or GitHub Actions + Fastlane. Automatic builds for every PR, distribution to TestFlight/Firebase App Distribution. Automated signing, no secrets in code.

Who it is for

Is It for You?

Flutter is for native apps with custom UI. If you have a React team, React Native may be better.

Who it's for

  • Companies needing native app for iOS and Android with single codebase.
  • Startups wanting maximum performance with optimized budget.
  • Projects with complex UI/UX requirements and fluid animations.
  • Teams willing to learn Dart or hire Flutter expertise.
  • Apps where visual consistency across platforms is an advantage.

Who it's not for

  • Teams with strong React/JavaScript investment (React Native better).
  • Apps that must feel 100% native to each platform.
  • Projects where PWA covers needs without native app.
  • Companies without capacity for a full-architecture native app project.
  • Very simple MVPs where no-code or templates suffice.

Risks and how we cover them

Risk Mitigation

How we protect your investment.

  1. 01

    Inconsistent performance (jank)

    Mitigation

    Profiling on every PR with Flutter DevTools. const constructors, RepaintBoundary, Isolates for heavy work.

  2. 02

    App Store rejection

    Mitigation

    Guidelines compliance from design. Pre-submission review with Apple checklist.

  3. 03

    Flutter becomes obsolete

    Mitigation

    Google uses it in core products (Ads, Pay). Active community. Public roadmap and steady stable releases.

  4. 04

    Maintenance difficulty

    Mitigation

    Documented Clean Architecture. Automated tests. Onboarding docs for future teams.

  5. 05

    Complex native integration

    Mitigation

    Platform Channels for specific Swift/Kotlin code when Flutter is not enough.

FAQ

Frequently Asked Questions

What Product Managers ask.

Flutter or React Native?

Flutter if: you want guaranteed 60fps, custom UI, and do not mind not "feeling native". React Native if: your team knows React, needs 100% native look per platform, or wants to share more code with web.

Is Flutter Web production ready?

For apps (dashboards, internal tools): yes. For websites with SEO: no, use Next.js. Flutter Web generates Canvas/WebGL, not semantic HTML. Google indexes poorly. For apps behind login, perfect. If you only need an installable web app, consider a PWA.

How much code is shared between iOS and Android?

95%+ of code is shared: business logic, state, UI widgets. The remaining 5%: platform channels for specific native APIs, per-platform UX adjustments, build configuration.

What happens with iOS/Android updates?

Flutter updates to support new APIs. Impeller engine improves iOS performance. We keep dependencies updated. Risk of "Flutter dies" is low: Google uses it in core products.

Can I use existing native code?

Yes. Platform Channels allow calling Swift/Kotlin code from Dart. Ideal for native SDKs (payment, AR, Bluetooth). No need to rewrite everything, just wrappers.

How are push notifications handled?

Firebase Cloud Messaging for both platforms. Native configuration for APNs (iOS) and FCM (Android). Local notifications with flutter_local_notifications. If you need your own backend for notifications and APIs, we build it with Node.js.

Is the design the same on iOS and Android?

By default, Flutter uses Material Design. We can apply Cupertino widgets for iOS or create custom design consistent on both platforms. Depends on desired branding.

How long does a typical project take?

MVP 5-8 screens: 8-10 weeks. Complete app with backend: 12-16 weeks. Enterprise with integrations: 16-24 weeks. Includes design, development, testing and submission.
