How to access items from List in Flutter

To access items from a List in Flutter we can use [] operator or elementAt() method or the getRange() method in case we want to get a group of items.

Access the item at a specified index in a List using the operator []

var list = [0, 1, 2, 'three'];
print(list[2]);
print(list[3]);

The output:

2
three

Access the item at specified index in a List using elementAt() method

var list = [0, 1, 2, 'three'];
print(list.elementAt(2));

The output:

2

Get a group of items by specifying the range in the List using getRange() method

var list = [0, 1, 2, 'three'];
print(list.getRange(1, 3).toList());

The output:

[1, 2]

Modify the item at a specified index in a List using the operator []

var list = [0, 1, 2, 'three'];
list[0] = 'zero';

print(list);

The output:

[zero, 1, 2, three]
