It needs to be in your path. See the instructions here:

Thanks for trying Flutter for web!

'dart' is not recognized as an internal or external command,
operable program or batch file.
'pub' is not recognized as an internal or external command,
operable program or batch file.

flutter packages pub global run webdev serve

This is somewhat related to this issue. When you activate a package, that script that is written to Pub's bin folder calls "dart" without any path. This means it'll fail if Dart isn't also in your PATH.

To fix this you can add "(flutter sdk)/bin/cache/dart-sdk/bin/" to your PATH, or you could continue to use the flutter packages version of the command.

FWIW, if you're using the editors, you shouldn't need to run these commands manually (for example in VS Code you can just open a Flutter web project and press F5 and it should launch webdev in the background for you) 🙂
