Dart Editor bitwise XOR showing as unknown

The current version of Dart Editor is showing the bitwise XOR operator as not defined for class bool

I don't see it defined in num.dart either.

Ex:

bool x = a ^ b;

The editor shows the "Caret" as not defined.

Update: Dart's api spec only allows bitwise XOR on integers. I fixed my code to properly work with bools.

You can use the XOR operator on booleans since Dart version 2.1

[...] since Dart 2.1, the bool class has had non-short-circuit operators &, | and ^.

They can be used where you want both sides to be evaluated, and, especially for ^, they can be used in assignments: bool parity = false; while (something) parity ^= checkSomething();.

Taken from the corresponding Github issue.

See the dart documentation for XOR here.

(Copied from the question, so that this appears as answered...)

Dart's spec only allows bitwise XOR on integers.
