calling firebase cloud function in flutter

Question

I've sent a function to firebase through typescript and don't know how to access it in my flutter app. The code needs to send the uid of the firebase user (the user will always already be logged in, so this isn't an issue) but then I also need to write into the function through message parameter, as is shown in my typescript code below. Again, I am unsure how to do this in Flutter.

This is my typescript code:

import * as functions from 'firebase-functions';

export const testFunction = functions.https.onCall( async (data, context) => {
    const uid = context.auth && context.auth.uid;
    const message = data.message;

    return `${uid} sent a message of ${message}`
});

Here is my Flutter code:

import 'package:cloud_functions/cloud_functions.dart';

Future<void> getFunction() async {
  HttpsCallable callable = FirebaseFunctions.instance.httpsCallable('testFunction', options: HttpsCallableOptions(timeout: Duration(seconds: 5)));
  final results = await callable();
  print('${results.data}');
}

@override
  void initState() {
    super.initState();
    getFunction();
}

As far as I can see in this documentation you can just pass the parameters into the call(...). Did you give that a try?
