Is there any alternatives ways to provides a viewModelScope?

Moved to this issue instead with more details and examples: https://github.com/google/dagger/issues/2004

viewModelScope is not a dispatcher, it’s CoroutineScope

You can get scope from it, using

viewModelScope.coroutineContext[CoroutineDispatcher]!!

Really apologize for miss information, I’ve update my code to use CoroutineScope instead. But still compile error because I still don’t know how to provide dependency inside view model like the above

[gildor]

Ahhh, I see, you cannot do this like that, you should inject view model into your method

[gildor]

To so that, you need component with view model

[gildor]

See this:
https://developer.android.com/training/dependency-injection/hilt-jetpack#viewmodels

[miqbaldc]

Do you mean something like this?

@DisableInstallInCheck
@Module
interface ViewModelModule {

    @get:[Binds LoginScope IntoMap ViewModelKey(LoginViewModel::class)]
    val LoginViewModel.loginViewModel: ViewModel

    companion object {
        @Provides
        fun provideLoginViewModelScope(viewModel: LoginViewModel): CoroutineScope = viewModel.viewModelScope
    }
}

Unfortunately, the above official docs doesn’t quite work for me (because using DFM). Thus vanilla dagger is needed, that’s why I’m using @DisableInstallInCheck in @Module configured inside DFM

[gildor]

DFM?

[miqbaldc]

my apologize, it stands for *D*ynamic *F*eature *M*odule, as stated in android studio official docs for using Hilt in multi-modules here: https://developer.android.com/training/dependency-injection/hilt-multi-module#dfm

[gildor]

Anyway, your original snippet is definitely impossible to make work, you cannot magically capture instance value, you need something like official doc, inject VM to this binding

Don't know exact details how inject VM, I would recommend to ask on Stackoverflow or report your case on dagger issue tracker

noted, really appreciate and a big thanks @gildor
