Can you explain what the Iterable interface means in programming?

The Iterable interface in programming refers to an object that can be traversed (iterated) over its elements, for example, in a for loop or using methods that work with collections.

In Dart (and Flutter), Iterable is a basic interface for collections that provide sequential access to their elements without needing to load them all at once.

Example of using Iterable in Dart:

void main() {
  Iterable<int> numbers = [1, 2, 3, 4, 5];
  for (var number in numbers) {
    print(number);
  }
}

Here, numbers is an Iterable, and we can iterate over it in a for loop. Iterable allows the use of methods such as map, where, reduce, and others for convenient working with sequences of data.
