What is Flutter App Development?

Flutter is Google’s open-source UI toolkit that lets you build natively compiled applications for iOS, Android, Web, and Desktop from a single codebase. Written in Dart, Flutter compiles to fast ARM or Intel machine code and renders using its own high-performance engine—delivering smooth animations, beautiful UIs, and native‑like performance.

Why businesses pick Flutter over React Native or fully native stacks: fewer platform-specific layers to maintain, consistent UI across devices, and faster delivery with Hot Reload. You get native capabilities with a smaller team—and a shorter path to market.
