Answer 1

Real answer on a real question about how to break forEach in if.

void main() {
  final seq1 = [0, 1, 2];
  final result = <int>[];
  try {
    seq1.forEach((e) {
      if (e == 2) throw 'Stop this immediately';
      result.add(e);
    });
  } catch (e) {
    // What? Something happened?
  }

  print(result);
}

Result:

[0, 1]

Not the most practical option, but it works.
That is, fully functional, for your case (break forEach).
The answer fully answers your question.
