Flutter for Web is built on the same core principles as Flutter for mobile apps, a single codebase that can run across multiple platforms. The key difference is that Flutter Web compiles your Dart code into browser-compatible JavaScript. This allows developers to use the same UI components, animations, and logic across both mobile and web applications.
Instead of using traditional HTML or CSS for web development, Flutter relies on its own rendering engine, Skia, to draw widgets directly to the screen. This approach gives developers full control over the visual appearance and behavior of their apps, ensuring that the look and feel are consistent across different devices and platforms.
By leveraging Flutter’s widget-based structure and rendering capabilities, web apps built with Flutter can achieve native-like performance, making it a viable option for web development alongside more traditional methods.

Flutter web architecture is built around a layered system, designed to deliver high performance and flexibility. At its core is the Dart Virtual Machine (VM), which compiles the Dart language into JavaScript for compatibility with web browsers. The compiled JavaScript code then interacts with the web’s DOM (Document Object Model) to render Flutter’s UI.
Flutter uses a rendering engine called Skia. This engine is responsible for rendering all the graphical elements of the app, including UI components, animations, and layouts. Unlike traditional web development that relies on the browser’s native rendering engine (such as HTML and CSS), Flutter draws everything directly to the screen, providing more control over the look and performance of the app.
Another essential component is the Flutter framework, which provides pre-built widgets that make development easier. These widgets are the building blocks of your app’s UI, enabling developers to create customized layouts and interactions without needing to write extensive custom code.
In summary, Flutter for Web uses Dart to compile code into JavaScript and relies on Skia for rendering, allowing developers to create highly interactive and visually rich web applications.
