Does hot reload work with a web app?

No, but you can use hot restart. Hot restart is a fast way of seeing your
changes without having to relaunch your web app and wait for it to compile and
load. This works similarly to the hot reload feature for Flutter mobile
development. The only difference is that hot reload remembers your state and hot
restart doesn’t.

How do I restart the app running in the browser?

You can either use the browser’s refresh button,
or you can enter “R” in the console where
“flutter run -d chrome” is running.

Which web browsers are supported by Flutter?

Flutter web apps can run on the following browsers:

Chrome (mobile & desktop)

Safari (mobile & desktop)

Edge (mobile & desktop)

Firefox (mobile & desktop)
