How to stop Dart's .forEach()?

List data = [1, 2, 3];
data.forEach((value) {
  if (value == 2) {
    // how to stop?
  }
  print(value);
});

Answer 1

It is also possible to implement your example using forEach() and takeWhile().

var data = [1, 2, 3];
data.takeWhile((val) => val != 2).forEach(print);
