What is Flutter Web?

A connected Progressive Web Application built with Flutter

Web support for Flutter enables existing mobile-based applications to be packaged as a PWA for reach to a broader variety of devices, or to provide a companion web experience to an existing app.

In addition to mobile apps, Flutter supports the generation of web content rendered using standards-based web technologies: HTML, CSS and JavaScript. With web support, you can compile existing Flutter code written in Dart into a client experience that can be embedded in the browser and deployed to any web server. You can use all the features of Flutter, and you don’t need a browser plug-in.

Flutter Solves The Backend & Frontend Problem

Flutter’s reactive framework brushes aside the need to get references to the widgets. On the other hand, it facilitates a single language to structure backend. That’s why Flutter is the best app development framework in the 21st century to be used by Android developers.

How to activate Flutter Web ?

if you want to install flutter check this article.

Run the following commands to use the latest version of the Flutter SDK from the beta channel and enable web support:

 $ flutter channel beta
 $ flutter upgrade
 $ flutter config --enable-web

Once web is enabled, the flutter devices command outputs a Chrome device that opens the Chrome browser with your app running, and a Web Server that provides the URL serving the app.

2 connected device:

Web Server • web-server • web-javascript • Flutter Tools
Chrome • chrome • web-javascript • Google Chrome 81.0.4044.129

Create and run

To create a new app that includes web support (in addition to mobile support), run the following commands, substituting myapp with the name of your project:

 $ flutter create myapp
 $ cd myapp

To serve your app from localhost in Chrome, enter the following from the top of the package:

$ flutter run -d chrome

A release build uses dart2js (instead of the development compiler) to produce a single JavaScript file main.dart.js. You can create a release build using release mode (flutter run --release) or by using flutter build web. This populates a build/web directory with built files, including an assets directory, which need to be served together.

Add web support to an existing app

To add web support to an existing project, run the following command in a terminal from the root project directory:

$ flutter create .
