Why Flutter, within boundaries
For most consumer mobile apps that need brand-consistent UI on both platforms, fast iteration and AI-assisted delivery, Flutter is our default. But "default" is not "always", the right answer depends on the product, and we keep native and web escape hatches open by design.
Why Flutter is our default
- Brand consistency by construction, Flutter renders its own pixel-identical UI on iOS and Android, so the design system is enforced by the framework instead of re-implemented per platform.
- One codebase, two platforms, and multi-brand support via runtime theming, not parallel codebases.
- Native performance, compiled to native ARM with a smooth 60/120 fps, including heavy lists and animations.
- AI-friendly by design, Dart's strong typing means AI-generated code compiles first try far more often, which matters when AI is doing much of the writing.
- Stable native access, first-party platform channels instead of fragile third-party bridges.
- Fast iteration, hot reload pairs naturally with AI-assisted development; many fixes ship via a backend release alone.
Flutter vs. React Native
| Dimension | React Native | Flutter (our default) |
|---|---|---|
| Rendering & brand | JS bridge to native widgets, UI drifts between iOS and Android; the design system is re-implemented per platform. | Own rendering engine, pixel-identical on both platforms; one widget tree enforces the brand everywhere. |
| Performance | JS thread can bottleneck on long lists, animations and WebView overlays. | Compiled to native ARM, steady 60/120 fps. |
| AI-assisted development | Loosely typed JS/TS, more hallucinated APIs from LLMs, caught later. | Strong typing in Dart, AI-generated code tends to compile first try; bad calls fail at build time. |
| Native access | Heavy reliance on third-party bridges that can break on OS updates. | First-party platform channels, stable, direct native access when needed. |
| Multi-brand | Often separate styling work per brand and platform. | Runtime theme switching from one codebase (e.g. two brands, one app). |
Both are capable frameworks used by major companies. The comparison is about fit for a brand-led, AI-assisted build, not an absolute verdict.
The boundaries
Flutter is the right call within limits we name up front:
- Native escape hatch. Platform-specific features (deep OS integrations, certain SDKs) are handled through platform channels, or a thin native Kotlin/Swift shell, Flutter doesn't have to do everything.
- WebViews for the long tail. Legacy or rarely-used flows can stay as authenticated WebViews inside the same shell, then be brought native as priorities allow.
- Talent, realistically. Senior Flutter talent is scarcer than React Native in some markets. We mitigate with AI-assisted onboarding (a new dev ramps by reading the codebase with AI), but it is a real planning factor, not a footnote.
- Not for every product. Heavily platform-specific apps, or those built around a vendor's native-only SDK, may be better served by native or another stack. We say so when that's the case.
In short: choose Flutter when cross-platform brand consistency, performance and AI-assisted speed matter most, and keep native and web escape hatches available for the parts that need them. The framework choice should serve the product, not the other way round.
