List.shuffle() in Dart?

Question

I'm looking every where on the web (dart website, stackoverflow, forums, etc), and I can't find my answer.

So there is my problem: I need to write a function, that print a random sort of a list, witch is provided as an argument. : In dart as well.

I try with maps, with Sets, with list ... I try the method with assert, with sort, I look at random method with Math on dart librabry ... nothing can do what I wana do.

Can some one help me with this?

Here some draft:

var element03 = query('#exercice03');   var uneliste03 = {'01':'Jean', '02':'Maximilien', '03':'Brigitte', '04':'Sonia', '05':'Jean-Pierre', '06':'Sandra'};   var alluneliste03 = new Map.from(uneliste03);   assert(uneliste03 != alluneliste03);   print(alluneliste03);    var ingredients = new Set();   ingredients.addAll(['Jean', 'Maximilien', 'Brigitte', 'Sonia', 'Jean-Pierre', 'Sandra']);   var alluneliste03 = new Map.from(ingredients);   assert(ingredients != alluneliste03);   //assert(ingredients.length == 4);    print(ingredients);    var fruits = <String>['bananas', 'apples', 'oranges'];   fruits.sort();   print(fruits);

There is a shuffle method in the List class. The methods shuffles the list in place. You can call it without an argument or provide a random number generator instance:

var list = ['a', 'b', 'c', 'd'];  list.shuffle();  print('$list');

The collection package comes with a shuffle function/extension that also supports specifying a sub range to shuffle:

void shuffle (   List list,   [int start = 0,   int end] )
