Deciding on a mono repository or a shared library
In this section, we're going to reason about the pros and cons of the following two repository setups:
- Mono Repository: This is where the shared code is just a module/submodule. This is the choice of most KMM/KMP example projects.
- Multiple Repositories: This is where the shared code is like a library that's consumed by the different platforms; that is, Android and iOS. Most production apps will likely see this option as more attractive.
