You can declare a common interface and wrap the implementation on each platform. Bottom line that's what makes kmp really powerful. You don't need to wait for nobody to make a kmp library for you, or provide kmp support for their sdk. In fact I have noticed that is what is killing Flutter, many people complaining about packages not being up to date and taking a long time to update. That is because most SDKs provider companies prioritize the native SDKs and if they have time and resources they do the multiplatform frameworks but some companies don't even care.
