Hi guys n00b question. What would be the best/right practice to have two viewModels talking each other. I have an object in the viewModelA and I need the ID in the viewModelB to have it on my request
Any recommendation?

[Alexa_Gal]

I'm using koin if it helps

[Orhan Tozan]

Use nav args?

[Alexa_Gal]

What if I have siblings fragments (view page) how could I listen for something or talk to the other view model?

[Orhan Tozan]

I need to know your usecase

[Alexa_Gal]

Let me elaborate something more concrete 🙏

[Alexa_Gal]

i Have an activity and inside that i have 3 fragments inside of a ViewPage. The viewPage is showing only when i request the userInfo (at the moment that information lives in the AcitivtyViewModel).
then i need to request a list of places,tickets, settings (each of them in different fragments) assuming that we are talking about get the list of places. i need in my PlacesViewModel request something like get(api/places/xxxxxxxx where xxxxxx is my user id that lives in ActivityViewModel.
Question how could i get the data in the ActivityViewMode in the other fragmentViewModels. Do i have to pass all the info in the nav args?
could koin help in the injection of properties?

[Orhan Tozan]

So you have a PlacesViewModel (fragment1), TicketsViewModel(f2) and SettingsViewModel(f3). What do you need the activity viewmodel for?

[Alexa_Gal]

yes, those are holding information only about their purpose.
In the mainActivity i have few LiveData as a global information.
DeviceInfo
User info
NetworkInfo
SessionStatus…

in my head i would like to have those properties available in each children view Model (the fragments) by injecting them as they need

[Orhan Tozan]

Put those data in a seperate component, and inject that into all 3 viewmodles

[Orhan Tozan]

Id like to avoid a parent vm and child vm, it is confusing

[Alexa_Gal]

what do you mean by seperate component? something like a shareViewModel?

[Orhan Tozan]

Something like a repository

Thanks let me try that :)
