change 127.0. 0.1(or localhost) to your IPV4 address.

To find IPV4 address. Open a command prompt and use "ipconfig" command. As bellow. enter image description here

If you're using django as backend, first run the server as "python manage.py runserver 0.0.0.0:8000". Then pass your local ip-address:8000 in the url in flutter, you can find your local ip-address by typing "ifconfig" in the terminal for macOs and linux or ipconfig in windows.

TLDR, use 10.0.2.2

Applications running in the Android emulator can connect to local HTTP web services via the 10.0.2.2 address, which is an alias to your host loopback interface (127.0. 0.1 on your development machine).
