Flutter Web Hosting

Flutter makes it simple and fast to build beautiful mobile apps for iOS, Android and desktop systems with one code base. It is also an excellent platform for building web apps or porting existing mobile apps to the browser as a PWA/SPA; its web support allowing developers to reach new audiences by showing their app on any device supporting HTML5.

To build a web app with Flutter, use the command flutter build web. This will generate a public directory under build/web with your compiled web app that you can then deploy onto Firebase Hosting with firebase deploy –only hosting public folder> and view in your browser by going to your Flutter project output URL.

Dependent upon the nature of your app, you have two primary renderer choices to select for its default renderer: HTML or CanvasKit. By setting an auto option as your default setting, your app should have optimal experience across platforms — while HTML renderers tend to work better on mobile devices, desktop browsers can often make better use of CanvasKit’s more robust features.

Minification and tree shaking are automatically performed for you when creating web apps in release builds; unlike debug builds where neither process occurs. A release build uses much smaller source files and optimizes performance more. You can specify a renderer by adding the “-renderer name>” flag when running build commands.
