Answer 1

OK, this is also my issue and I manage to find a workaround

1. on cmd run "ipconfig"

2. after running the "ipconfig" get the value of IPv4 Address.

3. then on the app run:

   flutter run -d chrome --web-port=8080 --web-hostname= *the value of IPv4 Address*
   

Answer 2

Go to Network LAN Properties -> Deselect the IPv6 Connectivity -> Click Ok. Its Works for me.
