The Constructor DSL could inject parameters via getOrNull()

[gary0707]

Is your feature request related to a problem? Please describe. In my code base, some of constructors use optional (nullable) parameters, which are not resolved correctly when I use the Constructor DSL like:

class FizzClass(val initialValue: Int?)

val someModule = module {
    factoryOf(::FizzClass)
}

The FizzClass is sometimes inject with a non-null value, but sometimes with null and to make that work I need to go with the classic DSL like:

val someModule = module {
    factory {
        FizzClass(initialValue = getOrNull())
    }
}

Describe the solution you'd like It would be great to be able to use the Constructor DSL also with nullable injected params.

Describe alternatives you've considered The only alternative I can see for now is the go with much more verbose classic Koin DSL.
