What would be an idiomatic way to pass an Integer via injection using koin? I want to use/inject a counter in different components. I know that a direct pass by ref is not possible (https://stackoverflow.com/questions/51638871/pass-an-integer-by-reference-in-kotlin)

[David Hernando]

you could wrap it in a data class

data class Counter(var value: Int)

[David Hernando]

then inject the data class instead

[David Hernando]

be aware that doing that is not thread safe and that if you are using the counter in a multithreaded environment in the jvm, an AtomicInteger should be preferred.

Thanks for the great help @David Hernando

Could also use inline classes if performance is a consideration

inline class Counter(var value: Int)
