✐ Examples

1 Convert iterable of numbers to list

In this example,

  1. We create an iterable named iterable containing integers.
  2. We call the toList() method on the iterable to convert it into a list.
  3. The resulting list contains all elements from the iterable.
  4. We print the list to standard output.

Dart Program

void main() {
  Iterable&lt;int&gt; iterable = [1, 2, 3, 4, 5];
  var list = iterable.toList();
  print(list);
}

Output

[1, 2, 3, 4, 5]

2 Convert iterable of characters to list

In this example,

  1. We create an iterable named iterable containing characters.
  2. We call the toList() method on the iterable to convert it into a list.
  3. The resulting list contains all elements from the iterable.
  4. We print the list to standard output.

Dart Program

void main() {
  Iterable&lt;String&gt; iterable = ['a', 'b', 'c'];
  var list = iterable.toList();
  print(list);
}

Output

[a, b, c]

3 Convert iterable of strings to list

In this example,

  1. We create an iterable named iterable containing strings.
  2. We call the toList() method on the iterable to convert it into a list.
  3. The resulting list contains all elements from the iterable.
  4. We print the list to standard output.

Dart Program

void main() {
  Iterable&lt;String&gt; iterable = ['apple', 'banana', 'cherry'];
  var list = iterable.toList();
  print(list);
}

Output

[apple, banana, cherry]
