The Flutter framework is built on three main layers: the framework layer, the engine layer, and the embedder layer. The framework layer is where developers interact with Flutter’s rich set of pre-designed widgets and tools. This layer provides a reactive framework for building user interfaces, enabling developers to create complex and dynamic UIs with ease. The framework layer also includes a comprehensive set of libraries for handling animations, gestures, and state management.
Beneath the framework layer is the engine layer, which is responsible for rendering the application’s UI. The engine layer leverages the Skia graphics engine to draw the UI elements on the screen. This layer also handles low level tasks such as text layout, image decoding, and GPU acceleration. The use of Skia ensures that Flutter applications can deliver smooth animations and high-performance rendering across different devices.
At the bottom of the stack is the embedder layer, which acts as a bridge between the Flutter engine and the underlying platform. The embedder layer is platform specific and handles tasks such as input events, window management, and platform-specific APIs. This layer ensures that Flutter applications can interact seamlessly with the native platform, providing access to device features and services. The modular architecture of Flutter allows developers to build high quality applications that run consistently across multiple platforms.
