Local module descriptor class for not found

I just started working with flutter and now I am working on this app. Every time the app is launched I get a lot of errors and have no idea how to fix them. The errors first occurred when I tried to authenticate users and now I don't know how to get rid of them. What's more, my isLogin bool is not being changed when pressing a button. I enclose a snippet of my code and a report of debug console errors. Thanks in advance.

  class _AuthCardState extends State<AuthCard> {
  @override
  Widget build(BuildContext context) {
    final _formKey = GlobalKey<FormState>();
    bool isLogin = true;
    final _passwordNode = FocusNode();
    final _conPasswordNode = FocusNode();
    print(isLogin);
    
    FirebaseAuth firebaseAuth = FirebaseAuth.instance;

    @override
    void dispose() {
      _passwordNode.dispose();
      _conPasswordNode.dispose();
      super.dispose();
    }

    void _authUser(String email, String password) {
      if (isLogin == false) {
        firebaseAuth.createUserWithEmailAndPassword(
          email: email,
          password: password,
        );
      } else {
        firebaseAuth.signInWithEmailAndPassword(
          email: email,
          password: password,
        );
      }
      _formKey.currentState!.save();
      dispose();
    }

    return Center(
      child: Card(
        margin: EdgeInsets.all(10),
        color: Theme.of(context).accentColor,
        child: Form(
          key: _formKey,

                    print('it works');
                  },
                ),
                TextFormField(
