Seems `null` parameter value can't be retrieved with `get()`. I created issue for that.

No this doesn't work... :pensive:

```package kointest

import org.junit.Test
import org.koin.core.context.startKoin
import org.koin.core.parameter.parametersOf
import org.koin.dsl.module
import kotlin.test.assertEquals
import kotlin.test.assertNull

class KoinTest {
    @Test
    fun testNullableParam() {
        val myModule = module {
            factory {
                MyFactory(
                    get(),
                    getOrNull(),
                    get()
                )
            }
        }

        val koin = startKoin {
            modules(myModule)
        }.koin

        val instance = koin.get&lt;MyFactory&gt; {
            parametersOf("param", null, "anotherParam")
        }

        assertEquals("param", instance.param)
        assertNull(instance.nullableParam)
        assertEquals("anotherParam", instance.anotherParam)
    }

    class MyFactory(val param: String, val nullableParam: String?, val anotherParam: String)
}```
Output:

Nullable parameter injection is tedious topic yes
