How to create composition over inheritance with koin?

[ArthurKun21]

ScriptScope.kt
AutoDetect.kt

@ScriptScope
class AutoDetect @Inject constructor(
    api: IFgoAutomataApi,
) : IFgoAutomataApi by api {

Normally it would have been

factoryOf(::AutoDetect ) { bind<IFgoAutomataApi>() }

But it seems off, how to actually migrate that code to koin

[arnaudgiuliani]

You need to have IFgoAutomataApi to be injected, as you use it in constructor

[ArthurKun21]

I was already doing something like this due to needing only in scope of service but I am getting error with this

scope(named(AUTOMATA_SCRIPT)) {
        scoped {
            AutoDetect(
                api = get(),
            )
        }

                            	at io.github.fate_grand_automata.runner.ScriptEntryPoint.getAutoDetect(ScriptEntryPoint.kt:9)

and trying to inject with this class

class ScriptEntryPoint : KoinComponent {

    val autoDetect: AutoDetect by inject()
}

even using like this

scope(named(AUTOMATA_SCRIPT)) {
        scoped<IFgoAutomataApi> {
            AutoDetect(
                api = get(),
            )
        }

also results in the same error.

The AutoDetect is actually on another module that I have been loading on the app module. is this possible be related on why it is not able to be instantiate? and if so, is there any way to remedy this situation?

I updated the code to become from Scoped to Factory. I did check the logs it appears that it got initialized

KoinLogging              D  [Koin] (+) index 'io.github.fate_grand_automata.scripts.entrypoints.AutoDetect::AutomataScript' -> '[Factory: 'io.github.fate_grand_automata.scripts.entrypoints.AutoDetect',scope:AutomataScript,binds:io.github.fate_grand_automata.scripts.IFgoAutomataApi]'
KoinLogging              D  [Koin] (+) index 'io.github.fate_grand_automata.scripts.entrypoints.AutoDetect::AutomataScript' -> '[Factory: 'io.github.fate_grand_automata.scripts.entrypoints.AutoDetect',scope:AutomataScript,binds:io.github.fate_grand_automata.scripts.IFgoAutomataApi]'

but when it was loading

class AutoDetect(
    api: IFgoAutomataApi,
) : IFgoAutomataApi by api {

interface IFgoAutomataApi : AutomataApi {
    val prefs: IPreferences
    val images: IImageLoader

class FgoAutomataApi(
    automataApi: AutomataApi,
    override val prefs: IPreferences,
    ....
) : IFgoAutomataApi,

class StandardAutomataApi(
    ....
) : AutomataApi {

interface AutomataApi {
...

another context is that we used to use dagger-hilt's EntryPoint for this stuff.

@EntryPoint
interface ScriptEntryPoint {
    fun autoDetect(): AutoDetect
