Can you name the main types of collections used in Dart?

In Dart, the main collection types are:

• List — an ordered list of elements, accessed by index.
• Set — an unordered collection of unique elements.
• Map — a collection of key-value pairs, where keys are unique.

Example usage:

var list = [1, 2, 3];
var set = {1, 2, 3};
var map = {'key1': 'value1', 'key2': 'value2'};
