Using when() cause The argument type 'Either<Failure, int>' can't be assigned to the parameter type 'dynamic Function()' about mocktail HOT 5 CLOSED

Ok got it. Thank you for your help @felangel

Hi @diazsasak 👋
Thanks for opening an issue!

I believe the issue is you need to pass a closure to when like:

when(() => mockInputConverter.stringToUnsignedInteger(any())).thenReturn(Right(numberParsed));

Let me know if that helps 👍

Hi @felangel ,
Thank you for your response.

yes that solve the problem for when(), and for untilCalled() and verify() also.

but i got another error on any. any suggestion?

`
when(() => mockInputConverter.stringToUnsignedInteger(any))
.thenReturn(Right(numberParsed));

  numberTriviaBloc.add(GetTriviaForConcreteNumber(numberString));

  await untilCalled(() => mockInputConverter.stringToUnsignedInteger(any));

  verify(() => mockInputConverter.stringToUnsignedInteger(numberString));

`

the error is
The argument type 'T Function<T>({String? named, Matcher? that})' can't be assigned to the parameter type 'String'

any is a function so it should be any() instead of any. Hope that helps 👍
