Flutter is an open-source UI software development kit (SDK) created by Google for building natively compiled, multi-platform applications from a single codebase.
It supports the development of applications for mobile (iOS, Android), web, desktop (Windows, macOS, Linux), and embedded devices.
Key Characteristics
- Language: It uses the Dart programming language, which is optimized for fast development and high performance.
- Widgets: The framework is built around a widget-based architecture where the user interface is composed of various customizable widgets.
- Performance: Flutter compiles code to native machine code (ARM/Intel) or JavaScript, allowing it to bypass traditional web views or bridges for high performance and smooth rendering via its own 2D rendering engine.
- Hot Reload: It features a "hot reload" capability that allows developers to see code changes in real-time without restarting the application.
- Cross-Platform: It enables developers to write code once and deploy it across six major platforms, significantly reducing development time and cost compared to native development.
