Firebase cloud functions not working with flutter web

[danielo17]

Hi all,

I developped a flutter app, which works ok for IOS and Android.
I am now busy with a flutter WEB version of it. So far everything OK. I configured firebase to access to the DB and developped my app. The access to firebase Database is working fine, I can access, read...etc.

BUT, I cannot manage to call from flutter WEB the cloud functions that I call with flutter IOS or flutter Android.

The call doesn't reach the backend, so I suspect might be something initializing (?). I´m new to flutter WEB, therefore it might be something really obvious to an expert.

It´s been already 2 weeks trying every possible option found in the docs so any help would be highly appreciated. Thanks in advance!

My config in index.html:

  <script type="module">
  // Import the functions you need from the SDKs you need
  import { initializeApp } from "https://www.gstatic.com/firebasejs/9.6.8/firebase-app.js";
  import { getFunctions } from "https://www.gstatic.com/firebasejs/9.6.8/firebase-functions.js";

  const firebaseConfig = {
    apiKey: "myData",
    authDomain: "myData",
    projectId: "myData",
    storageBucket: "myData",
    messagingSenderId: "myData",
    appId: "myData",
    measurementId: "myData"
  };

  // Initialize Firebase
  const app = initializeApp(firebaseConfig);
  const functions = getFunctions(app);
</script>

I also initialize firebase in the flutter code:

  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(options: const FirebaseOptions(
      apiKey: "myData",
      authDomain: "myData",
      projectId: "myData",
      storageBucket: "myData",
      messagingSenderId: "myData",
      appId: "myData",
      measurementId: "myData"));

  runApp(MyApp());

The error I get: [firebase_functions/internal] internal
