    As of

    Flutter 3.7.8 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 90c64ed42b (6 days ago) • 2023-03-21 11:27:08 -0500
Engine • revision 9aa7816315
Tools • Dart 2.19.5 • DevTools 2.20.1

    this ceased to be an issue. I can flutter run on a public WiFi.

    Update

    Now at

    [✓] Flutter (Channel stable, 3.7.10,
on macOS 11.7.4 20G1120 darwin-x64, locale en-CA)

    it's again a problem, with the error

    SocketException: Failed host lookup: 'localhost'
(OS Error: nodename nor servname provided,
or not known, errno = 8)

    hence the question is once again open.

    Use your IP

    The following may work for you

    flutter run -d chrome --web-port=8080 --web-hostname=101.112.123.1349

    where the four numbers are your IP.

    Try to use your IP’s machine, if you don’t know, you can try opening a cmd terminal in windows and type ipconfig and get your local IP. Or terminal in linux/mac type ifconfig and find your local IP
