What we call Ternary If is a short use of the if control structure. You can see its usage in the example below.

Syntax:

condition ? exprIfTrue : exprIfFalse

Normal if else usage:

int height = 185;
String heightCategory = '';

main() {
  if (height > 175) {
    heightCategory = 'Tall';
  } else {
    heightCategory = 'Short';
  }
  print(heightCategory);
}

Using Ternary If operators:

main() {
  int height = 185;
  String heightCategory = height > 175 ? "Tall" : "Short";
  print(heightCategory);
}

Operators and function structures are no different from other C-based programming languages. We will not go into details.
