Choosing the right cross-platform framework is a million-rupee decision.
React Native (Meta)
React Native uses JavaScript, making it very easy to find developers in India. It's great if your team already uses React for the web. Popular apps like Myntra and Flipkart have heavily leveraged it.
Flutter (Google)
Flutter uses Dart and compiles to native code, offering arguably smoother animations and a very consistent UI across iOS and Android. Startups like Cred and Zerodha use Flutter for its unmatched fluid experience.
Verdict
If you want complex animations and a bespoke UI, choose Flutter. If you want a larger talent pool and code-sharing with web, choose React Native.
