Flutter is an open-source UI toolkit created by Google that lets developers build natively compiled apps for mobile (iOS & Android), web, and desktop from a single codebase. Since its stable release in 2018, it has become one of the most popular mobile development frameworks in the world.
How Flutter Works
Unlike React Native (which uses JavaScript bridges to communicate with native UI components), Flutter renders its own UI using the Skia/Impeller graphics engine directly to the screen. This means Flutter controls every pixel — giving it exceptional rendering consistency and performance.
What is Dart?
Flutter apps are written in Dart — a strongly-typed, object-oriented language also made by Google. Dart is easy to learn if you know Java, JavaScript, or C#. It compiles to ARM machine code for mobile (fast native execution) and to JavaScript for web.
What Can You Build with Flutter?
Virtually any type of mobile app: e-commerce, healthcare, fintech, edtech, social, on-demand services, productivity tools. Flutter is used in production by Google (Google Pay), Alibaba (Xianyu with 50 M+ users), BMW, and thousands of startups globally.
Why Hire a Flutter Developer?
Hiring a Flutter developer means you get both your iOS and Android apps from a single developer, at roughly half the cost of building two native apps. The app feels native on both platforms, the codebase is maintainable, and future updates need to be made only once.
