Every mobile project starts with the same question: native or cross-platform? Most teams either pick one and use it for everything, or they let the framework wars on Twitter decide for them. Both are mistakes.

The simple version

Use Flutter when:

  • You need iOS and Android, and your team is small (1-3 mobile devs)
  • Your app is mostly content, lists, forms, and CRUD — basically anything that's not a game
  • You want to iterate fast and don't mind the design feeling slightly "Flutter-ish" by default
  • You have a tight budget — the cost difference is typically 30-50% less than two native codebases

Use native (Swift or Kotlin) when:

  • You need deep platform integration — widgets, complications, Live Activities, deep linking with Universal Links, App Clips, advanced background tasks
  • You're shipping ARKit, RealityKit, or anything that uses platform-specific frameworks
  • You need every millisecond of performance — high-fps animations, real-time audio/video processing, games
  • You're a one-platform company (iOS-only or Android-only is genuinely fine in many B2B contexts in India)

What people get wrong

"Flutter looks cheap." Out of the box, yes. With deliberate styling, no. The Helio patient app is Flutter and most users assume it's native iOS. The trick is to not use Material Design defaults on iOS — implement the native-feeling components yourself or use a library that does. It takes a couple of weeks of upfront work and then it's fine.

"Flutter performance is bad." This was true four years ago. It is not true now for the apps most businesses build. We have Flutter apps doing 60fps complex list scrolling, animated charts, and offline-first data sync without issue. If you're rendering a game or doing video effects, that's different.

"Native is too expensive for B2C apps." It depends on the team. A senior iOS developer and a senior Android developer working in parallel can ship faster than two mid-level Flutter developers. Talent matters more than framework choice for medium-sized apps.

The Flutter-specific lessons

Things we've learned the hard way:

  • State management is a hill to climb. Provider, Riverpod, Bloc, GetX — each has religious followers and real downsides. We use Riverpod and have been happy. Pick one and don't switch mid-project.
  • Native platform integrations need a native developer. Anything that touches the keychain, secure enclave, biometrics, or background processes will eventually need someone who actually knows Swift or Kotlin. Budget for this.
  • Releases are still platform-specific. App Store review, Play Store review, signing, provisioning — Flutter doesn't make any of this easier. Plan for both stores' rules.
  • Dart is fine. It's not exciting, but it's stable, fast, and easy to hire for now. The language is not the reason Flutter projects fail.

Where we land

For most of our client work — apps that serve as the mobile face of a business — we default to Flutter. For products where the mobile experience itself is the product, or where deep OS integration matters, we still go native. We've never once regretted picking Flutter for the right project, and we've never once regretted picking native for the right project either. The framework wars on Twitter are about identity. Pick the tool that fits the job.
