Cucumber for Dart won't create/link step definitions in Flutter app

I have a Flutter app where I want to create automated test cases. When I created first feature file like this

    Feature: LoginFeature
  As I tester I want to test login page features


  Scenario Outline:
    Given I log in as "<Username>" with "<Password>"
    #Then I get the error message "Message"

  Examples:
    | Case | Username      | Password  | Message    |
    | 1    | abcd@efgh.com | user1pass | lsijadklams|

I created a step definition manually and it looks like this

import 'package:flutter_gherkin/flutter_gherkin.dart';
import 'package:gherkin/gherkin.dart';

import '../page_objects/login_page.dart';

StepDefinitionGeneric GivenILoginAsWith() {
  return given2<String, String, FlutterWorld>(
    RegExp(r'I log in as {string} with {string}'),
        (email, pass, context) async {
          LoginPage loginPage = new LoginPage(context.world.driver);
          loginPage.setEmail(email);
          loginPage.setPassword(pass);
          loginPage.tapOnLogin();
    },
  );
}

Where LoginPage is a class where I define all page objects.

But when I navigate to feature file I get this message

And after Selecting as a Quick fix "Create a step definition" and selecting particular document where it should be imported I get this error in Stacktrace

PS: I am using flutter_gherkin, gherkin and Ogurets - Cucumber for Dart.

Am I doing something wrong?

Thanks
