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?

[kursivee]

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?

[Joost Klitsie]

are you compiling with java 1.8?

[marios proto]

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

SalesApplication.salesComponent().inject(this)

[marios proto]

even better consider to support FragmentFactory and move to constructor injection rather than properties injection
