Just to clarify, I understand DI well enough, but I wouldn’t know how to provide, say, the equivalent of a Dagger module that injects library objects with platform implementations. I wonder if I’m overthinking it, or if anyone could point me to an example of a good way to achieve this goal.

Perhaps you can use ServiceLoader. It's only for jvm though

why not just inject a concrete implementation of an interface directly as a constructor parameter?

Yeah I'm also not a fan of depending on libraries for DI. I think kotlin makes it pretty easy without.

Thanks for the suggestions guys. I didn’t mean to suggest I wanted to use Dagger in MPP, just that I wondered if anything similar (either a library or a good example of the DI pattern) was available for common code.

i know there are kotlin libraries for DI, however i don't know if they're compatible with native/multiplatform
