I am trying to have Either<Failure, Concrete> where Concrete extends Abstract class, but I cannot get it to work. If I try to cast the left side I get the error:
type 'Right<Failure, Concrete>' is not a subtype of type 'Either<Failure, Abstract>' in type cast
if I try for the right side I get:
type 'Left<Object, Concrete>' is not a subtype of type 'Either<Failure, Concrete>' in type cast
And bimap does not seems to solve it. Is there an easy way to do it? tks
@jalvespinto got same problem like yours. In my case i am returning value as Right(value). when i changed my code to below . it worked.
Before
return Right(User())
After
return Right<Failure,User>(User());
