The architecture of Flutter consists of several layers, each responsible for a specific aspect of the application's operation:
-
Framework – the top layer, written in Dart. It contains widgets, state management, rendering, and user interaction logic. Developers mainly work with this layer.
-
Engine – written in C++, it provides low-level graphics (via Skia), input processing, access to platform APIs, and rendering management.
-
Embedder – adapts the engine for a specific platform (Android, iOS, Windows, etc.), ensuring integration with the OS, managing the application's lifecycle, and accessing system resources.
Thus, Flutter builds the application from top to bottom: the developer creates UI and logic in Dart, which are then rendered and run on a specific device through the engine and embedder layers. This structure ensures high performance and cross-platform compatibility.
