Common Questions

Frequently Asked

Flutter delivers near-native performance with 95-99% code sharing across platforms. While native development offers slightly better platform-specific optimisations, Flutter dramatically reduces development time and maintenance costs for multi-platform apps.

Flutter compiles to native ARM code and uses the Skia graphics engine to render at 120fps. Performance is comparable to native apps for most use cases, with advanced optimisation techniques for graphics-intensive applications.

Yes. Flutter web is production-ready and supports both single-page applications and progressive web apps. We optimise for web-specific concerns like SEO, initial load time, and responsive layouts.

Typically 95-99% of business logic and UI code is shared. Platform-specific code is only needed for native API integrations via platform channels, which we encapsulate in reusable plugins.
