Depends

Should I use Flutter?

Build apps for any screen from a single codebase - flutter.dev

· 1 month ago

Use Flutter if you have (or will hire) developers and want one free codebase for iOS, Android, web and desktop. Skip it if nobody on your team writes code — a no-code builder or templates will serve you better than learning Dart.

The real cost: developmentVaries

Best for

  • Startups shipping one app to iOS and Android
  • Teams with design-heavy custom UIs
  • Budget-conscious MVPs with in-house devs
  • Dart-comfortable engineering teams

Not for

  • Non-coders wanting an app — learn a no-code tool instead
  • Simple one-screen apps — templates are cheaper than a framework
  • Teams needing deep native Swift/Kotlin features
  • Web-first products — Flutter web support is contested

Gotchas - check before you buy

medium

Free SDK, expensive app: even simple Flutter apps carry real development price tags

medium

Dart code rarely ports to native Swift/Kotlin — expect rewrite-level migration pain if you leave

low

Don't confuse with FlutterFlow — a separate paid no-code product whose plan changes upset users

low

Community contributors report funding gaps; longevity leans on Google's continued backing

Pros and cons

Free, mature cross-platform SDK — great with Dart-capable devs; overkill if you just need a simple app without coding.
