如何從Dart的列表中獲得隨機元素？

Question

如何從Dart中的集合中檢索隨機元素？

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

這工作太：

var list = ['a','b','c','d','e']; 
var randomItem = (list..shuffle()).first;
