Does Dart's ?? operator short-circuit?

To check this, I decided to create a small example. Here’s the function I used.

int? show(int x, [bool isNull = false]) {
  print(x);
  return isNull ? null : x;
}

When we run the following

show(10) ?? show(11);

it prints

10

Now let’s try with a null value

show(10, true) ?? show(11);

which prints

10
11

This means that Dart uses short-circuiting for ?? operator!
