How Does Flutter Function?

How Does Flutter Function?

Flutter functions as a framework for building web applications by facilitating the translation of Dart code into HTML, CSS, and JavaScript, making it possible for web developers to create dynamic and interactive web experiences.

Here’s a breakdown of how Flutter works for web development:

Dart Code Processing:

The development process begins with writing Dart code, the programming language used by Flutter. Flutter Web allows developers to create web applications using Dart, a language focusing on performance, developer productivity, and a strong type system.

Flutter Web Engine:

The Dart code is processed and compiled into HTML and CSS using the tools and APIs provided by the Flutter Web Engine. The Flutter Web Engine is the core runtime environment for web applications developed with Flutter. It is pivotal in translating Flutter widgets and logic into web-compatible components.

JavaScript Compilation:

In addition to generating HTML and CSS, Flutter Web compiles the Dart code into JavaScript. JavaScript is a widely supported scripting language in web browsers and is necessary for web applications to execute client-side logic and interact with the browser’s Document Object Model (DOM).

Files for the Browser:

Once the Dart code has been processed, compiled into HTML, CSS, and JavaScript, and bundled together, the resulting files are sent to the user’s web browser. These files include the HTML structure that defines the web application, the CSS styles for layout and appearance, and the JavaScript code for interactivity and functionality.

Rendering Engines:

Flutter Web offers developers a choice between two distinct rendering engines for rendering the user interface:

  • DomCanvas: DomCanvas is Flutter’s default rendering engine for the Web. It uses the DOM (Document Object Model) to create and manipulate the elements displayed on the web page. It is well-suited for most web development scenarios and offers native-like rendering capabilities.
  • CanvasKit: CanvasKit is an alternative rendering engine that uses WebAssembly and WebGL. It offers even higher performance and may be a preferred choice for applications that require complex graphics and animations.

Both rendering engines provide flexibility and performance, allowing developers to choose the one that best suits the requirements of their web application.
