# operator | method Null safety

- int other

Bit-wise 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 either
of `this`

and `other`

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

## Implementation

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