So aparently when you are debugging it in web mode, you need to pass this option in the initializer function-

await Firebase.initializeApp(
    options: FirebaseOptions(
        apiKey: "",
        appId: "",
        messagingSenderId: "",
        projectId: ""),
  );

You also have to initialize Firebase in index.html; here is the documentation.
