Why MovieDetailsAnimator is not injected as a @Singleton?

[minchaej]

First of all, thank you so much for this awesome repository.

I have a question about dependency injection:
You inject MovieDetailsAnimator
@Inject lateinit var movieDetailsAnimator: MovieDetailsAnimator
at line 60, MovieDetailsFragment.kt.

And MovieDetailsAnimator is constructed through
class MovieDetailsAnimator @Inject constructor()

Wouldn't it be better if MovieDetailsAnimator was constructed with @singleton annotation? Something like:
@Singleton class MovieDetailsAnimator @Inject constructor()
It seems like there is no point on getting a new instance of MovieDetailsAnimator for every fragment.

Thank you! 👍
