如何在测试（Flutter）中访问这些字段？

Question

I have these fields below in-state class and I want to test if these fields work correctly. So I write testing dart file, how can I access these field in a testing file

class _LoginPageState extends State<LoginPage> {
      String _phoneNumber = "";
  String _smsCode = "";
  String _verificationId = "";
  int _currentStep = 0;

  List<StepState> _stepsState = [
    StepState.editing,
    StepState.indexed,
    StepState.indexed
  ];

  bool _showProgress = false;
  String _displayName = '';
  File _imageFile;

  bool _labeling = false;

  List<ImageLabel> _labels = List();

}

You can use @visibleForTesting annotation from any of these packages

import 'package:flutter/widgets.dart';
import 'package:meta/meta.dart';
