This page covers the following steps for getting started with web support:
Requirements
To create a Flutter app with web support,you need the following software:
For more information, see the web FAQ.
Note: Flutter has early support for running web applications, but you need to be running the
beta channel of Flutter at present. If you experience a problem that hasn’t yet been reported, please file an issue and make sure that “web” appears in the title.
Create a new project with web support
You can use the following stepsto create a new project with web support.
Set up
Run the following commands to use the latest version of the Flutter SDKfrom the beta channel and enable web support:
Warning: Running
flutter channel beta replaces your current version of Flutter with the beta version and can take time if your connection is slow. After this, running flutter upgrade upgrades your install to the latest beta . Returning to the stable channel (or any other) requires calling flutter channel <channel> explicitly.
Note: The
flutter upgrade command silently fails when origin points to a personal fork. To validate that origin points to https://github.com/flutter/flutter.git , run the following commands in the root directory of your local copy of the https://github.com/flutter/flutter repository:
Once web is enabled,the
flutter devices command outputs a Chrome devicethat opens the Chrome browser with your app running,and a Web Server Adobe premiere pro mac student. that provides the URL serving the app.
After enabling web support, restart your IDE.You should now see Chrome (web) andWeb Server (web) in the device pulldown.
Note: You only need to execute
flutter config --enable-web once. You can always check the status of your configuration using the no-argument flutter config command.

Once you’ve configured your environment for websupport, you can create and run a web app eitherin the IDE or from the command line.
IDE
After you’ve configured your environment to supportthe web, make sure you restart the IDE if it wasalready running.
Create a new app in your IDE and it automaticallycreates iOS, Android, and web versions of your app.(And macOS, too, if you’ve enabled desktop support.)From the device pulldown, select Chrome (web)and run your app to see it launch in Chrome.
Command line
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:
To serve your app from
localhost in Chrome,enter the following from the top of the package:
Note: If there aren’t any other connected devices, the
-d chrome is optional.
The
flutter run command launches the application using thedevelopment compiler in a Chrome browser.
Build
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 directorywith built files, including an assets directory,which need to be served together.
You can also include
--web-renderer html or --web-renderer canvaskit toselect between the HTML or CanvasKit renderers, respsectively. For moreinformation, see Web renderers.
