operator ^ method Null safety

int? operator ^(
  1. int other
)

Bit-wise exclusive-or operator.

Treating both this and other as sufficiently large two's component integers, the result is a number with the bits set that are set in one, but not both, of this and other

If the operands have the same sign, the result is non-negative, otherwise the result is negative.

Implementation

int? operator ^(int other) {
  if (value != null) {
    return value! ^ other;
  }
}
