Why Flutter is popular

Flutter, introduced by Google in 2017, is an open-source UI toolkit for crafting natively compiled applications across mobile, web, and desktop platforms from a single codebase. It utilizes the Dart programming language, enabling developers to build high-performance apps with expressive and flexible UIs. One of Flutter's standout features is its "hot reload" functionality, allowing for real-time code changes without restarting the application, thereby accelerating the development process. The framework offers a rich set of pre-designed widgets adhering to both Material Design and Cupertino aesthetics, ensuring a native-like user experience on Android and iOS devices. By maintaining a single codebase, Flutter simplifies maintenance and reduces development costs, making it a popular choice for startups and enterprises alike. Its architecture comprises the Flutter engine, written in C++, which interfaces with platform-specific SDKs, and the Foundation library, providing essential classes and functions. Flutter's growing community and comprehensive documentation further facilitate rapid development and deployment of applications. As a result, Flutter has become a versatile and efficient solution for cross-platform app development.
