What should be the endpoint address when I use Flutter + Deno + MongoDB?

[goodmanworld]

I am using Flutter, VSCode and Android emulator in Windows 10. Also Deno as the backend server. I am trying to connect Flutter app to Deno app locally in my PC. But I don't know what address exactly I must use?

This is the address I am trying to send get, post, etc. requests from the Flutter app to:

http://10.0.2.2:8000/api/register

And this is the address I am trying to receive those requests inside my deno app:

Listening on: http://0.0.0.0:8000

And the endpoints such as /api/register work when I use postman to test them with the follwong address for example:

0.0.0.0:8000/api/register

I don't know what is the problem and how can I fix it?
