This page covers the following steps for getting started with web support:

To create a Flutter app with web support, you need the following software:

For more information, see the web FAQ.

You can use the following steps to create a new project with web support.

Run the following commands to use the latest version of the Flutter SDK:

report_problem Warning: Running flutter channel stable replaces your current version of Flutter with the stable version and can take time if your connection is slow. After this, running flutter upgrade upgrades your install to the latest stable. Returning to another channel (beta or master) requires calling flutter channel explicitly.

If Chrome is installed, 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.

In your IDE, you should see Chrome (web) in the device pulldown.

Creating a new project with web support is no different than creating a new Flutter project for other platforms.

Create a new app in your IDE and it automatically creates iOS, Android, desktop, and web versions of your app. From the device pulldown, select Chrome (web) and run your app to see it launch in Chrome.

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

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

info Note: If there aren’t any other connected devices, the -d chrome is optional.

The flutter run command launches the application using the development compiler in a Chrome browser.

report_problem Warning: Hot reload is not supported in a web browser Currently, Flutter supports hot restart, but not hot reload in a web browser.

Run the following command to generate a release build:

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.

You can also include --web-renderer html or --web-renderer canvaskit to select between the HTML or CanvasKit renderers, respectively. For more information, see Web renderers.

For more information, see Build and release a web app.

To add web support to an existing project created using a previous version of Flutter, run the following command from your project’s top-level directory:
