Flutter vs React Native: My Honest Take After 25+ Apps

I've shipped apps in both frameworks. My React Native era ended around 2021, and I haven't looked back. Here's the honest breakdown—without the fanboy nonsense.

Performance: The Gap Is Real

Flutter renders its own UI using Skia (now Impeller). React Native bridges JavaScript to native components. That bridge is where performance problems live. For most startup MVPs you won't notice the difference—but the moment you build complex animations, a custom camera experience, or a real-time collaborative feature, Flutter pulls away.

Concrete data point: a client's React Native app had 200ms+ scroll jank on Android mid-range devices. The same UI rebuilt in Flutter? Buttery smooth on a 2019 Galaxy A20.

Developer Experience

Hot reload in Flutter is faster and more reliable. Dart feels verbose at first, then becomes a superpower—strongly typed, null-safe by default, and the tooling catches bugs before they reach users. React Native's JavaScript lets any web developer jump in immediately. That's a real advantage if your team already writes React. But 'any web developer can build it' often becomes 'any web developer breaks it' in production.

The Ecosystem Question

React Native wins here—npm has everything. Flutter's pub.dev has grown dramatically but gaps still exist, particularly around cutting-edge AI SDKs and enterprise-grade integrations. My workaround: Flutter's interop with native Swift/Kotlin is excellent. If a package doesn't exist in pub.dev, I write a thin native wrapper. Takes a few hours; pays for itself in reliability.

When I Still Recommend React Native

• Your team is 100% JavaScript and retraining isn't an option
• You need to ship a WebView-heavy app (Flutter's WebView is still catching up)
• You're extending an existing React Native codebase with significant investment

My Rule of Thumb

New project, greenfield, funded startup? Flutter. Every time.

“Build on the platform that makes your app feel like a product, not a web page wrapped in native chrome.”

After 25+ mobile apps, I've never had a client regret choosing Flutter. I've had two regret React Native.
