addQuestion method

void addQuestion(dynamic p_question, dynamic key, { dynamic is_boolean = false, dynamic is_list = false, dynamic is_message = false, })

This method is another way of adding questions after instantiating CLI_Dialog Pass is_bool or is_list as a named argument to indicate the type of question you are adding (boolean qualifier).

final dialog = CLI_Dialog();
dialog.addQuestion([{'question': 'How are you?', options: ['Good', 'Not so good']}, 'mood'], is_list: true);

Implementation

void addQuestion(p_question, key,
    {is_boolean = false, is_list = false, is_message = false}) {
  if ((is_boolean ? 1 : 0) + (is_list ? 1 : 0) + (is_message ? 1 : 0) > 1) {
    throw ArgumentError(
        'A question can not have more than one boolean qualifier.');
  }
  final newItem = [p_question, key];
  if (is_boolean) {
    booleanQuestions!.add(newItem);
  } else if (is_list) {
    listQuestions!.add(newItem);
  } else if (is_message) {
    messages!.add(newItem);
  } else {
    questions!.add(newItem);
  }
}
