Start With the Team, Not the Framework
If your team has strong React and JavaScript experience, React Native carries a meaningful advantage: existing component patterns transfer directly, state management libraries (Zustand, Jotai) work identically, and real code sharing with your web product becomes possible. If the team has no JavaScript experience, Flutter’s Dart learning curve is not meaningfully steeper, and its documentation and tooling quality are excellent.
UI Requirements
Flutter’s rendering engine draws every pixel independently of the platform. This is a genuine advantage for applications requiring custom shader animations, complex canvas drawing operations, or pixel-identical UI across iOS and Android. React Native composes native platform components by default — your app feels naturally “at home” on each platform, which is what most business applications need.
Ecosystem Reality in 2025
For enterprise SDK integrations — Stripe, Mapbox, Firebase, Segment, Braze — React Native has more battle-tested solutions. Flutter’s pub.dev has improved significantly but still has gaps in enterprise-specific integrations.
Our Default
JavaScript team or existing React web codebase: React Native. Complex custom animations or desktop target alongside mobile: Flutter. Genuinely uncertain: build the most complex screen in both frameworks as a prototype, then let the result inform the decision.
