web support for flutter
flutter’s web support delivers the same experiences on the web as on mobile.
building on the portability of dart, the power of the web platform and the
flexibility of the flutter framework, you can now build apps for iOS, android,
and the browser from the same codebase. you can compile existing flutter code
written in dart into a web experience because it is exactly the same flutter
framework and web is just another device target for your app.
adding web support to flutter involved implementing flutter’s
core drawing layer on top of standard browser APIs, in addition
to compiling dart to JavaScript, instead of the ARM machine code that
is used for mobile applications. using a combination of DOM, canvas,
and WebAssembly, flutter can provide a portable, high-quality,
and performant user experience across modern browsers.
we implemented the core drawing layer completely in dart
and used dart’s optimized JavaScript compiler to compile the
flutter core and framework along with your application
into a single, minified source file that can be deployed to
any web server.
while you can do a lot on the web,
flutter’s web support is most valuable in the
following scenarios:
not every HTML scenario is ideally suited for flutter at this time.
for example, text-rich, flow-based, static content such as blog articles
benefit from the document-centric model that the web is built around,
rather than the app-centric services that a UI framework like flutter
can deliver. however, you can use flutter to embed interactive
experiences into these websites.

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

set up
run the following commands to use the latest version of the flutter SDK:
warning 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 <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.

create and run
creating a new project with web support is no different
than creating a new flutter project for other platforms.

IDE
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.

command line
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.

hot reload is not supported in a web browser
currently, flutter supports hot restart,
