I have a module containing

@Provides
    @Singleton
    fun providesMessageCenter(): MessageCenter = MessageCenter()

for me, this seems to be quite unnecessary and I guess I could annotate the

MessageCenter

class directly instead to get it into the graph. Whats the best way of doing this (or is the best way to keep it as it is?)

@Singleton
class MessageCenter @Inject constructor()

should do the trick and you could remove the

@Provides

method.

@Inject is the only way of getting it to the graph?

Without a provision method, i.e @Provides or @Binds, @Inject is only the way to automatically add it to the graph.

ok, thanks
