How do get a random element from a List in Dart?

Question

How can I retrieve a random element from a collection in Dart?

var list = ['a','b','c','d','e']; 

Answer 1

import "dart:math";  var list = ['a','b','c','d','e'];  // generates a new Random object final _random = new Random();  // generate a random index based on the list length // and use it to retrieve the element var element = list[_random.nextInt(list.length)]; 

Answer 2

This works too:

var list = ['a','b','c','d','e'];  //this actually changes the order of all of the elements in the list  //randomly, then returns the first element of the new list var randomItem = (list..shuffle()).first; 

or if you don't want to mess the list, create a copy:

var randomItem = (list.toList()..shuffle()).first;
