Android & iOS App using MVVM pattern and LiveData on the presentation layer + Clean Arch on the common shared code.

Kotlin-Multiplatform MVVM (Android & iOS)

Example of application using Kotlin Multiplatform and MVVM pattern for both platforms (Android & iOS). To achieve it the libraries used are:

• moko-mvvm: This is a Kotlin Multiplatform library that provides architecture components of Model-View-ViewModel for UI applications. Components are lifecycle-aware on Android.
• KTOR: to make HTTP requests
• Serialization: to De/Serializing JSON
• Kodein-DI: Dependency injector
• kotlinx.coroutines: Library support for Kotlin coroutines with multiplatform support
• SQLDelight: SQLDelight generates typesafe kotlin APIs from your SQL statements.

kotlinmultiplatform_mvvm's Issues

Question : About Kodein

Is Kodein the only DI tool that can be used or its just preference.

I Use Koin before multiplaform and want to know if i can use it

Question: LiveData + lifecycle

Hey, Javier. I only see you are using dev.icerock.moko.mvvm.livedata.LiveData.addObserver(), but you never do dev.icerock.moko.mvvm.livedata.LiveData.removeObserver(). Is it intentional?
If I add removeObserver() in onPause() and do addObserver() in onResume() - do you see any potential memory leaks here? compared to android's viewmodel.livaData.observe(viewLifecycleOwner, {})

About native-mt coroutines

Does the viewmodelscope in moko mvvm not need
withcontext(Dispatchers.Default){

////code here runs on background thread on both ios/android since viewmodel is in common module
}
and moko livedata postvalue emits to UI thread on both ios/android plaform

Is my understanding correct, if not without changing context the operations run on background thread and gets emitted in moko livedata. Please explain how background threads happen for network/db operations in the written codebase for viewmodel.
