A complete guide to Flutter architecture

Flutter, a UI toolkit developed by Google, enables the creation of natively compiled applications for web, desktop, and mobile platforms from a single codebase. Its architecture comprises three layers: the Embedder, Engine, and Framework, each playing a crucial role in rendering and managing Flutter applications. The Embedder layer acts as a platform-specific entry point, while the Engine, written in C/C++, handles low-level operations such as rendering and network requests using Skia. The Framework layer, written in Dart, is the primary interface for developers, offering a reactive and modern structure with widgets as fundamental elements. Flutter's use of a singular codebase for multiple platforms, combined with features like hot reload and a native rendering engine, results in efficient, high-performance applications with consistent UI across platforms. This approach reduces development and market release times, making Flutter a compelling option for developers seeking to build cross-platform applications. Additionally, Flutter's open-source nature and active community support contribute to its growing popularity and robust documentation.
