here list_id must be listId
please follow the camel case for local variable, to overcome this issue you can use @SerializedName("list_id") Gson Annotation to specify the variables comes from the api side.

(this is not a must, I just put this comment with comparing to clean code architecture with MVVM)
there is no domain layer. its better to have a interface called ShopListRepository inside the repository list folder in domain folder.
in the network data layer you can use implementation class of it "ShopListRepositoryIml"

no need to pass LiveData with function here. just observe the eventLiveData filed from fragment. remove function here. and make eventLiveData public.

add this repository into the constructor in MainViewModel.

name is not meaning full. function is returing data. not update events

put minifyEnable true in release mode only. create separate debug mode for development (security concern)

use lateInit and make MainViewModel not null ( remove ?)
and you can remove force null check on line number 36, and 52

progressBar?.visibility = View.GONE

widget fields must be class scope and should not init inside observe functions. this assigin must be out side the observe function and inside onViewCreated

val latestIcon = view.findViewById(R.id.latest_list_icon) should be the same above

here application logics and model conversons should not inside the fragment or activities. keep them inside the viewModel.
(move "mapShopList" function inside to the viewModel)
icon set Url also must be inside the ViewModel
