The full answer
Flutter renders its own user interface rather than relying on each platform's native widgets, so screens look and behave the same on iPhone and Android devices. For products with a strong brand or a custom design system that consistency is a real advantage, and it makes animation-heavy interfaces easier to build well.
Creuto uses Flutter for consumer apps, booking and marketplace products, field apps and internal tools, the kinds of products where a shared codebase keeps two platforms moving at the same pace and halves the cost of every new feature.
A Flutter app still needs a solid backend. Creuto typically pairs it with a NestJS or FastAPI service, a PostgreSQL database and cloud infrastructure on AWS, Azure or Google Cloud, with CI/CD pipelines that build, sign and distribute test versions automatically.
Where an app depends heavily on platform features, such as advanced camera control, background processing or specific hardware, Creuto writes native modules in Swift or Kotlin and bridges them into Flutter, or recommends a fully native build if that is the better fit.
Creuto can publish the finished app to the App Store and Google Play and support it after launch. The Flutter versus React Native decision is made in discovery, based on your team, design and integration needs.
