How do i inject viewmodelScope in dagger 2 - dagger-2

Question

I am using dagger 2 with coroutine and paging architecture. I want paging Datasource load with vary viewmodelScope but don't know how to inject viewmodelScope in dagger 2
DataSource. All functions in network and database are suspend function so I must pass a scope.
class NewsDataSource #Inject constructor(
private val apiService: ApiService,
private val newsDao: NewsDao,
private val scope: CoroutineScope
) : PageKeyedDataSource<Int, Article>() {
private val _listNews = MutableLiveData<PagedList<Article>>()
val listNews: LiveData<PagedList<Article>>
get() = _listNews
override fun loadInitial(
params: LoadInitialParams<Int>,
callback: LoadInitialCallback<Int, Article>
) {
scope.launch {
val result = apiService.getNews(1, params.requestedLoadSize)
when (result) {
is Result.Success -> {
callback.onResult(result.data.articles, null, 2)
}
}
}
}
}
DataSourceFactory
class NewsDataSourceFactory #Inject constructor(
private val apiService: ApiService,
private val newsDao: NewsDao,
private val scope: CoroutineScope
) : DataSource.Factory<Int, Article>() {
val newsDataSourceLiveData = MutableLiveData<NewsDataSource>()
override fun create(): DataSource<Int, Article> {
val newsDataSource = NewsDataSource(apiService, newsDao, scope)
newsDataSourceLiveData.postValue(newsDataSource)
return newsDataSource
}
}
and my repository
class NewsRepositoryImp #Inject constructor(
private val newsApi: ApiService,
private val newsDao: NewsDao,
private val scope: CoroutineScope
) : INewsRepository {
override suspend fun getNews(): PagedList<Article> {
val sourceFactory = NewsDataSourceFactory(newsApi, newsDao, scope)
val pagedListConfig = PagedList.Config.Builder()
.setEnablePlaceholders(false)
.setInitialLoadSizeHint(10)
.setPageSize(20)
.build()
val livePagedList = LivePagedListBuilder(sourceFactory, pagedListConfig).build()
return livePagedList.value!!
}
}
How do I pass viewmodelScope for this?
