✐ Examples

1 Convert runes to list

In this example,

  1. We create a sequence of Unicode code points runes from the string 'Hello'.
  2. We use the toList method to convert the runes into a List of integers.
  3. We then print the resulting list to standard output.

Dart Program

void main() {
  Runes runes = Runes('Hello');
  List<int> runeList = runes.toList();
  print('Rune list: $runeList');
}

Output

Rune list: [72, 101, 108, 108, 111]

2 Convert numbers to list

In this example,

  1. We create a sequence of Unicode code points numbers from the string '12345'.
  2. We use the toList method to convert the numbers into a List of integers.
  3. We then print the resulting list to standard output.

Dart Program

void main() {
  Runes numbers = Runes('12345');
  List<int> numberList = numbers.toList();
  print('Number list: $numberList');
}

Output

Number list: [49, 50, 51, 52, 53]
