Getting List elements in Flutter

I have an ArrayList with elements for example:

var x = [1,2,3,4,5,6];

how can I store only the first 3 [1,2,3] elements in another list?

You can use the take function as @Christopher Moore said or the sublist function

var x = [1, 2, 3, 4, 5, 6];

var usingTake = x.take(3).toList(); // 1,2,3
var usingSubList = x.sublist(0, 3); // 1,2,3

You can also use sublist to take any portion of the list.

For example: Getting the last 3 elements will be like:

var x = [1, 2, 3, 4, 5, 6];
var usingSubList = x.sublist(x.length - 3, x.length);

Use the take function:

var x = [1,2,3,4,5,6];

var y = x.take(3).toList();
