How can I call local Firebase Functions (in Emulator) from Flutter?

I set up Cloud Functions in the local emulator. I wrote a few functions and tested them in the browser with the function emulator. Now I am trying to call these functions from my local Flutter app without deploying them. However, i cannot find a way to connect my Flutter App to the localhost API of the functions. Is there anyway to do that?

In steps:

1. Import the package:

   import 'package:cloud_functions/cloud_functions.dart';
   

2. Create an instance:

   static final _functions = FirebaseFunctions.instance;
   

3. Wire it up to the emulator:

   final origin = Platform.isAndroid ? 'http://10.0.2.2:5001' : 'http://localhost:5001';
   _functions.useFunctionsEmulator(origin: origin);
