Injecting ViewModel into the Fragment with Dagger 2, with parameters

I'm trying to use a single factory for creating ViewModels with constructor parameters. I followed the recommendation in one of the open dagger issues by @matejdro https://github.com/google/dagger/issues/1273

But the injection doesn't work.

I"m getting an error:"error: [Dagger/MissingBinding] kotlin.Lazy cannot be provided without an @Provides-annotated method."

Any idea how to resolve the issue? I uploaded my created project to github: https://github.com/davida5/daggerViewModelBestPractice

Solution

  • That's pretty simple, you should be using dagger.Lazy (include an import for it) instead of the kotlin.Lazy

    Once that is fixed you will run into another issue though; AFAIK you can't use a qualified dependency without a corresponding qualified provider. You have a qualified UserManager instance being injected into AccountsViewModel. Either add a qualified provider method or remove the qualification from the AccountsViewModel.
