Hey guys, I keep on getting

viewModelFactory lateinit has not been initialized errpr

when injecting a dagger view model factory into a fragment and initialising the viewmodel using viewmodel lazy delegate property, here is a snippet of my code.. Error :

Fatal Exception: kotlin.UninitializedPropertyAccessException
lateinit property viewModelFactory has not been initialized

Code:

class DeliveriesFragment() : Fragment(){

    @Inject
    lateinit var daggerViewModelFactory: DaggerViewModelFactory
    private val upcomingDeliveriesViewModel : UpcomingDeliveriesViewModel by viewModels { daggerViewModelFactory }

    override fun onAttach(context: Context) {
        SalesApplication.salesComponent().inject(this)
        super.onAttach(context)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        observeDeliveries()
    }

    private fun observeDeliveries(){
        upcomingDeliveriesViewModel.loadUpcomingUserDeliveries("").observe(viewLifecycleOwner, Observer {
            //displayList()
        })
    }
}

What is lateinit exactly doing?

the error references

viewModelFactory

but that class has

daggerViewModelFactory

is it somewhere else? the code looks correct though.

Are you declare

DeliveriesFragment

in DI Module?

are you compiling with java 1.8?

check that you have the DaggerVMFactory in your graph. call this on onCreate

SalesApplication.salesComponent().inject(this)
