Flutter · One codebase, native feel
How does Flutter compare with React Native?
Short answer
Flutter renders its own UI from Dart, while React Native drives native views from JavaScript or TypeScript. The trade-offs centre on UI consistency, native fidelity, ecosystem and team skills.
Flutter compiles Dart and paints through its engine, so layout and styling are consistent across platforms. React Native renders platform views through a bridge or the newer architecture, so controls inherit more native behaviour but can differ between iOS and Android. Neither choice is universally better; the constraints decide.
- UI consistency: Flutter is strong when every platform should look identical
- Native feel: React Native can reuse platform components and behaviours more directly
- Language: Dart with sound null safety versus TypeScript and the JavaScript ecosystem
- Ecosystem: React Native benefits from JS libraries; Flutter relies on pub.dev and plugin quality
- Performance: both are production-grade, but profiling differs because Flutter paints everything
class Counter extends StatefulWidget {
const Counter({super.key});
@override
State<Counter> createState() => _CounterState();
}
class _CounterState extends State<Counter> {
int count = 0;
@override
Widget build(BuildContext context) {
return FilledButton(
onPressed: () => setState(() => count += 1),
child: Text('Tapped ' + count.toString() + ' times'),
);
}
}How I would choose
I start from product requirements. If the team is TypeScript-heavy and the app is mostly forms and native-feeling lists, React Native may reduce ramp-up. If pixel-identical design, custom animation and a single rendering model matter, Flutter is attractive. I also check plugin maturity for the specific hardware integrations the product needs.
Follow-ups you should expect
Interviewers use these to check whether the first answer was understanding or memorisation.
- 1Which framework would you pick for a heavily native camera app and why?
- 2How does the rendering model affect visual consistency?
- 3What is the cost of introducing Dart to a TypeScript team?
- 4How would you evaluate plugin maturity before committing?
Say it in the interview
Flutter renders its own scene from Dart, while React Native uses JavaScript or TypeScript to drive native views. That means Flutter gives very consistent UI across platforms, and React Native can inherit more native behaviour. I would choose based on the team's skills, the required native integrations, and whether visual consistency or native fidelity matters more. I would not pick either purely on a benchmark claim.
Use this as a model, not a script. Saying it in your own words is what makes it survive follow-up pressure.
