Dart New Set and Map

Creating a new Set

Sets can be created via the constructor:

var ingredients = new Set();
ingredients.addAll(['gold', 'titanium', 'xenon']);

Creating a new Map

Maps can be created in multiple ways.

Using the constructor, you can create a new map as follow:

var searchTerms = new Map();

Types for the key and value can also be defined using generics:

var nobleGases = new Map<int, String>();
var nobleGases = <int, String>{};

Maps can otherwise be created using the map literal:

var map = {
 "key1": "value1",
 "key2": "value2"
