CLI_Dialog class

This is the most important class which should usually be instantiated when building CLI dialogs.

Constructors

CLI_Dialog({List? messages, List? questions, List? booleanQuestions, List? listQuestions, List<String>? order, bool trueByDefault = false, bool navigationMode = false, String? resume = ''})

This is the default constructor to create a CLI Dialog You can pass lists of normal questions, booleanQuestions, listQuestions. All these named parameters are optional as long as at least one of them is given. Furthermore you can pass a particular order. If no order is given then the default order is used (see README.md) There is also trueByDefault (false by default) which indicates how booleanQuestions behave if no input is given There are basic format checks which try to prevent you from passing invalid argmuents.

CLI_Dialog.std(StdinService _std_input, StdoutService _std_output, {List? messages, List? questions, List? booleanQuestions, List? listQuestions, List<String>? order, bool trueByDefault = false, bool navigationMode = false})

This named constructor should mostly be used when unit testing.

Properties

answers ↔ Map

This is where the results = answers from the CLI dialog go. This map is updated and returned when calling ask.

getter/setter pair

booleanQuestions ↔ List?

This is where the boolean questions are stored during runtime. Feel free to access it like any other list.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

listQuestions ↔ List?

This is where the list questions are stored during runtime (where the user selects a value). Feel free to access it like any other list.

getter/setter pair

messages ↔ List?

Messages inform the user without asking a question. A key must be provided for each message if you want to use a custom order.

getter/setter pair

navigationMode ↔ bool

Navigation mode means that every question is displayed with a number which you can use to navigate through questions

getter/setter pair

order ↔ List<String>?

This list contains the order in which the questions are asked in the dialog. Feel free to access it like any other list.

getter/setter pair

questions ↔ List?

This is where the regular questions are stored during runtime.

getter/setter pair

resume ↔ String?

Resume moed means that progress in your CLI dialog is automatically saved with each question so you can savely Quit and resume later. Specify a file path where you progress will be saved and loaded from

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

trueByDefault ↔ bool

Indicates the default behaviour of boolean questions when no input (except '\n') is given.

getter/setter pair

Methods

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

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).

addQuestions(dynamic p_questions, {dynamic is_boolean = false, dynamic is_list = false, dynamic is_message = false}) → void

Same as addQuestion but you can add multiple questions (of the same type)

ask() → Map

Use this method to retrieve the results from your CLI dialog. A map is being returned which you can query using your keys.

getCustomNavList() → List

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
