This Slack is a good place reach them, they are here and sometimes answer 🙂
One issue I think is that the number of libraries in KMP expanding very fast, and also CMP/KMP ecosystem. So a lot of things in sample projects quickly becoming deprecated things or old things.
Given that, doing a larger sample app will become even more fragmented and most probably not fit all enterprises, as they are widely different in size and needs.
My recommendation is to check existing KMP apps published and are open source. Also asking what you want to know.
Also multiplatform things in general is confusing in the beginning. If you dont have experience in all supported platforms, its harder. Imagine youre iOS developer and want to go Kotlin multiplatform, its complicated.
Then add new things like wasm, different desktop OS, TV etc on top of that.
Very hard recommend something 🙂
