如何将 Fragment 的参数项添加到 Koin 依赖图中？

Question

I have a ViewModel which has a dependency which should be taken from the Fragment 's arguments .

So its something like:

class SomeViewModel(someValue: SomeValue)

now the fragment recieves the SomeValue in its arguemnt like so:

class SomeFragment : Fragment() {
    val someViewModel: SomeViewModel by viewModel()

    companion object {
        fun newInstance(someValue: SomeValue) = SomeFragment().apply {
            arguments = bundleof("someKey" to someValue)
        }
    }
}

problem is I don't know how to add SomeValue thats taken from the Fragment 's arguments to Koin 's module.

Is there a way to make the fragment contribute to the Koin Dependency Graph?

So for anyone else asking the same question, here is the answer:

https://doc.insert-koin.io/#/koin-core/injection-parameters

So basically,

you could create your module like so:

val myModule = module {
    viewModel { (someValue : SomeValue) -> SomeViewModel(someValue ) }
}

Now in your fragment, you could do something like:

class SomeFragment : Fragment() {
    val someViewModel: SomeViewModel by viewModel { 
        parametersOf(argument!!.getParcelable<SomeValue>("someKey")) 
    }

    companion object {
        fun newInstance(someValue: SomeValue) = SomeFragment().apply {
            arguments = bundleof("someKey" to someValue)
        }
    }
}
