Receiving data from localhost throws 'Connection Refused Error'

I'm running a flutter app and trying to receive a json from localhost using:

Future<String> getJson() async {
    http.Response response = await http.get(
      Uri.encodeFull("http://localhost:3000/get"),
      headers: {
        "Accept": "application/json"
      }
    );

Whenever I run the app, I get an unhandled exception:

SocketException: OS Error: Connection refused, errno = 111, address = 127.0.0.1, port = 48134

The port 48134 is open. Now, I thought of maybe changing my listening port to the port above. Doing that, switches the port in the error to some other random port and giving the same error.
I don't understand why it's even looking for that port. It's not written anywhere.
Anyone has any ideas? Thanks in advance.

You are aware that `localhost`/`127.0.0.1` in Flutter is your emulator or phone, not your development machine? – Günter Zöchbauer Dec 01 '17 at 12:37
I am definitely not. So what do I do if I have two projects on localhost with different ports and I want to access one from the other? – Amit Toren Dec 01 '17 at 16:28

Got it. You can access the machine's localhost using `10.0.2.2`. Was not aware of what you said. Thank you :) – Amit Toren Dec 01 '17 at 16:44
Didn't know about `10.0.2.2.` :D Glad to hear you figured it out. – Günter Zöchbauer Dec 01 '17 at 16:52

Didn't know about the 10.0.2.2 either. – eyoeldefare Nov 08 '18 at 03:04
