Overview
What Flutter Is
Flutter is an open-source UI toolkit from Google for building applications for mobile (iOS and Android), web, desktop, and embedded devices from a single codebase. First released in 2017, it uses the Dart language and a widget-based architecture. Rather than wrapping native components, Flutter draws its own interface, giving pixel-level control and a consistent look across platforms.
How It Works
Flutter apps are built from composable widgets that define both structure and styling. A high-performance rendering engine paints every pixel, so the interface looks and behaves the same everywhere. Hot reload injects code changes in seconds without losing app state, speeding iteration, while release builds compile to native ARM code for strong runtime performance.
Why It Matters for Your Business
Flutter lets one team build for iOS and Android — and often web — at once, cutting cost and time versus maintaining separate native codebases, while keeping a polished, branded UI. Our in-house Flutter app development and mobile app development teams use it for products where a fast, consistent cross-platform experience from a single codebase delivers the most value.

FAQ
Flutter — common questions
Is Flutter better than React Native?
Neither is universally better. Flutter uses Dart and renders its own UI for highly consistent visuals and strong performance; React Native uses JavaScript and native components, with a larger JavaScript ecosystem. The best fit depends on your team's skills and product needs.
What programming language does Flutter use?
Flutter apps are written in Dart, a Google language optimized for building user interfaces. Dart compiles to native code for mobile and desktop and to JavaScript for the web.
Is Flutter good for production apps?
Yes. Flutter is stable and used by many large companies in production. It is an especially strong choice for cross-platform apps that need a custom, consistent UI, though very hardware-specific features may still call for some native code.
