The argument

A Flutter app is just widgets, composed all the way down.

Each widget · a contract. Each rebuild · scoped, not global. Each pixel · identical on every device.

09 — Questions

Things people
actually ask.

Flutter is our default when a product needs one team shipping to iOS, Android, and often web or desktop, with UI that matches pixel-for-pixel across all of them. We reach for native (Swift/Kotlin) when a feature leans hard on platform-specific APIs — deep AR, background processing edge cases — and React Native when a team already has a large React web codebase to share logic with. Most product briefs land on Flutter.
Yes — Flutter renders its own widget tree via Impeller rather than wrapping native components, so it doesn't inherit platform UI quirks, but that also means motion, haptics, and platform conventions have to be deliberately matched. We build with Material 3 and Cupertino adaptive widgets so iOS gets iOS conventions and Android gets Android ones, from the same codebase.
Usually, yes. Flutter Web and Flutter Desktop (macOS, Windows, Linux) compile from the same widget tree as mobile. We scope this early — layout needs to adapt to pointer input and wider viewports — but for internal tools and B2B products, one codebase across four platforms is a common and realistic target.
Isar or Hive for local-first storage, with a sync layer that reconciles against the backend on reconnect. Conflict resolution rules are scoped per entity during architecture — last-write-wins is rarely the right default for anything a user edits directly.
Design tokens land as Dart theme data, not a Figma file. Components ship as a widget library with golden tests locking in pixel output, so a designer's spacing and type scale can't silently drift after handoff. Designers and engineers review the same running app, not a static comp.
You do. Repo, CI pipeline, App Store Connect and Play Console access — all transferred or provisioned under your accounts from day one. All work is delivered under a work-for-hire clause; we keep no embedded SDKs or licensing strings attached.
