takeUnless
Returns this value when predicate is false, or null otherwise.
The predicate receives the original value, including null, and runs once. Its exceptions propagate and the inline predicate supports non-local returns. A null result can mean either rejection or acceptance of a null receiver.
Receiver
value to test.
Return
the original receiver when the predicate is false, or null when it is true.
Parameters
predicate
test that returns true to reject the value.
Type Parameters
T
type of the receiver, which may be nullable.
