Build Beautiful Apps for iOS, Android & Web
Flutter is Google's UI framework for crafting natively compiled applications from a single code base. Fast development, expressive UIs, and 60fps performance across platforms.
Why Flutter for cross-platform development?
Flutter takes a different approach to cross-platform mobile development. Instead of using JavaScript bridges (like React Native) or WebViews, Flutter compiles directly to native ARM code and uses its own rendering engine (Skia). This means consistent 60fps performance and pixel-perfect UIs that look and feel native.
Google uses Flutter for many of its own apps, including Google Pay, Google Ads, and Stadia. Companies like Alibaba, BMW, and eBay have adopted Flutter for their mobile apps. The framework has grown beyond mobile—you can now build web and desktop apps with the same codebase, though mobile remains its strongest use case.
At Devionary, we build Flutter apps for clients who prioritize beautiful, custom UIs and fast time-to-market. Flutter's hot reload lets us iterate on designs rapidly during development. The framework's widget-based architecture makes it easy to create consistent, reusable UI components. We use Flutter when clients need high visual fidelity and smooth animations.
Why choose Flutter?
Single Codebase
Write once, deploy to iOS, Android, web, Windows, macOS, and Linux. Share 95%+ of code across platforms. Maintain one project instead of six.
Hot Reload
See code changes instantly without losing app state. Iterate on UI designs in seconds. Dramatically faster development cycle than traditional native development.
Beautiful UIs
Rich set of customizable widgets. Material Design and Cupertino (iOS-style) components out of the box. Easy to create custom, branded designs.
Native Performance
Compiles to native ARM code. Own rendering engine (Skia). Consistent 60fps animations. No JavaScript bridge overhead.
Growing Ecosystem
Backed by Google with regular updates. 30,000+ packages on pub.dev. Active community solving common problems. First-class IDE support (VS Code, Android Studio).
Dart Language
Modern, type-safe language. Familiar syntax for JavaScript and Java developers. Fast compilation. Null safety prevents entire classes of bugs.

Flutter vs. React Native: Which to choose?
Choose Flutter when:
- You need complex, custom UI with animations
- Performance is critical (60fps animations)
- You want pixel-perfect consistency across platforms
- The team can learn Dart (similar to TypeScript/Java)
Choose React Native when:
- You have existing React/JavaScript developers
- You want to share code with React web app
- You need access to more JavaScript libraries
- OTA updates are important (CodePush)
Our recommendation: Both are excellent. Flutter often has an edge for visually rich apps and games. React Native is preferred when JavaScript expertise exists. We can help you choose based on your specific requirements.
When Flutter excels
Visually rich applications
Apps with complex animations, custom graphics, and unique brand experiences benefit from Flutter's rendering engine and widget library.
Consistent cross-platform UX
Flutter apps look and behave identically on iOS and Android. No platform-specific quirks or layout differences to debug.
MVP development
Hot reload accelerates iteration cycles. Build and test features quickly. Perfect for startups validating product-market fit.
Performance-critical apps
Native compilation ensures smooth 60fps performance. Games, animation-heavy apps, and real-time applications perform well.
