How would you share little bits of logic across view models? Lets say function sized - no state

[bohsen]

Using delegation and compose your ViewModel using this

Example:

class SampleViewModel @Inject constructor(private val sampleInteractor: SampleInteractor) :
    ViewModel(), SampleDialogContract.Interactor by sampleInteractor

Why not use functions then?

where would you keep them?

[Dariusz Rusin]

business logic is not the part of ViewModel. ViemModel should use domain services. Then that little bit of domain logic will stay same between all of ViewModels.

[Dariusz Rusin]

I dont know who and when popularized that way of ViewModel understanding.

Depends. too general to talk like that. Also one liner use cases are stupid

[tschuchort]

You can put the functions wherever. In the same file or in a different file
