is it possible to write a contract where somthing implies, that a method will not return

null

? (all examples i can find implie the other way round)

I think that if by design your method can either be nullable or no-nullable, depending on a variable

damn, that would be far easier, thats right 😄

Can you show us an example of what you're trying to do?

in fact you are just right - i should split it into two methods. you know that sitautions where you feel really stupid for not seeing the obvious? 😂

Oh... we've all been there, Malte! :-D

And we'll be there many more times

na not really... the emssage has a boolean flag (which is bad on it's own, too), and when it's

false

it will return a non-null value - always. i knew this smeels before, but then i saw a colleague using it, and he had to use

?.

all over the place and i though "hey this is kotlin! it has a cool feature that might solve this problem" and didn't realise it would be much easier to simply split the method into two

I like how Kotlin makes some code smells even more smelly hahaha

😄
