Giannis Tsironis, injecting DialogFragments are no different than injecting regular or support Fragments. I created an [ISSUE] for your question, which I have answered in this [PR], which adds support for injecting DialogFragments in the companion GitHub project for this article.

If you already have a project using Dagger 2.11 setup, you would most likely only need to change 1 line of code in order to support injecting DialogFragments. That is, you would need to either have your BaseFragment subclass DialogFragment instead of Fragment OR subclass DaggerDialogFragment introduced in Dagger 2.12.

Here is a screenshot of the [PR] description if you want a quick peek.
