  2. We access its sign property to get its sign.
  3. We then print the result to standard output.

Dart Program

  int number1 = 10;
  int sign1 = number1.sign;
  print('Sign of $number1: $sign1');
}

Dart Program

void main() {
  int number2 = -7;
  int sign2 = number2.sign;
  print('Sign of $number2: $sign2');
}

Output

Sign of -7: -1

3 Sign of zero
