    isLoading.value = Status.loading;
    try {
      UserModel? user = await repository.signInWithEmailAndPassword(
            emailTextController.text, passwordTextController.text);
  
      if (user != null) {
        box.write(&quot;auth&quot;, user);
        QR.navigator.replaceAll('/initial');
      }
    } on AuthException catch (error) {
      throw AuthExceptionController(title: error.title, content: error.content);
    } finally {
      isLoading.value = Status.success;
    }
  }
  
  // page
  onPressed: () {
    if (_formKey.currentState!.validate()) {
      try {
        _authenticationController.login(context);
      } on AuthExceptionController catch (error) {
        ScaffoldMessenger.of(context).showSnackBar(
          SnackBar(content: Text(error.content)));
