operator & method Null safety

int? operator &(
  1. int other
)

Bit-wise and operator.

Treating both this and other as sufficiently large two's component integers, the result is a number with only the bits set that are set in both this and other

If both operands are negative, the result is negative, otherwise the result is non-negative.

Implementation

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