Flutter, an open-source UI software development toolkit from Google, is noteworthy for its capacity to generate natively compiled applications for mobile, web, and desktop using a unified codebase.
At Vast Edge, our adeptness in crafting dynamic and secure applications through Flutter underscores our comprehensive familiarity and profound expertise in the Flutter framework. This proficiency equips us to construct applications distinguished by their scalability, security, and performance.
Flutter widgets are associated with elements. An element is a lightweight, mutable, and ephemeral representation of a widget. Elements are managed by the framework and are responsible for updating widgets in response to events such as user input or data changes.
At the core of Flutter's architecture are widgets. Everything in Flutter is a widget, including structural elements like app bars and buttons, as well as stylistic elements like padding and colors. Widgets are lightweight and are used to construct the user interface of the app.
Render Objects are responsible for painting, layout, and compositing. They define a geometry for a widget and can contain children Render Objects. Render Objects are highly optimized for performance and are responsible for creating a render tree, which represents what appears on the screen.
In this layer, Flutter creates a layer tree that represents the composition of all the visuals in the widget tree. Each layer in the layer tree corresponds to a RenderObject in the RenderObject tree. The layer tree is then composited into the final scene, which is rendered on the device's screen.
The engine layer is where the C/C++ code of the Flutter engine resides. It includes Skia, a 2D rendering engine, and other platform-specific code to interact with the device's hardware. The engine layer is responsible for platform-specific tasks such as drawing text, managing gestures, and handling input events.
