I am converting my whole project into Koin. Using Koin KMP (I am converting right now my shared module).
And I have multiple modules, that are being executed in one main module (which the main contains the references to the others), for organisation proposes only.
Here's my Main Module:

if (isDebug) {
configuration.saveAppEnvironment(AppEnvironment.Qa)
} else {
configuration.saveAppEnvironment(AppEnvironment.Prod)
}
configuration.saveFirstLaunch(false)
}
}
}
Here's the child module, per example ConfigurationKoinInitializer.
package pt.custojusto.configuration
import kotlinx.coroutines.CoroutineScope
import org.koin.core.component.KoinComponent
import org.koin.core.component.inject
import org.koin.core.context.startKoin
import org.koin.dsl.module
import pt.custojusto.configuration.firebase.FeatureTogglesFirebaseRemoteConfig
import pt.custojusto.configuration.repositories.configuration.ConfigurationRepository
import pt.custojusto.configuration.repositories.configuration.ConfigurationRepositoryImpl
import pt.custojusto.configuration.repositories.featuretoggles.FeatureTogglesRepository
import pt.custojusto.configuration.repositories.featuretoggles.FeatureTogglesRepositoryImpl
import pt.custojusto.configuration.services.configuration.ConfigurationService
import pt.custojusto.configuration.services.configuration.ConfigurationServiceImpl
import pt.custojusto.configuration.services.featuretoggles.FeatureTogglesService
import pt.custojusto.configuration.services.featuretoggles.configuratorapp.FeatureTogglesConfiguratorAppService
import pt.custojusto.configuration.services.featuretoggles.local.FeatureTogglesLocalService
class ConfigurationKoinInitializer(
coroutineScope: CoroutineScope,
configuratorAppFeatureTogglesService: FeatureTogglesConfiguratorAppService,
firebaseRemoteConfig: FeatureTogglesFirebaseRemoteConfig
) : KoinComponent {
val configurationService: ConfigurationService by inject()
val featureTogglesService: FeatureTogglesService by inject()
val configurationRepository: ConfigurationRepository by inject()
val featureTogglesRepository: FeatureTogglesRepository by inject()
val configurationModule = module {
single { coroutineScope }
single { configuratorAppFeatureTogglesService }
single { firebaseRemoteConfig }
single { ConfigurationServiceImpl(get()) }
single { FeatureTogglesLocalService() }
single { ConfigurationRepositoryImpl(get()) }
single {
FeatureTogglesRepositoryImpl(
get(),
get(),
get(),
get()
)
}
}
}
When building the app, it gives me an error about the initialisers, that I have on my KoinModules. I've tried to initialise with the get() (example: configurationKoinInitializer = get() ) and by the normal way we initialise things
(example: configurationKoinInitializer = ConfigurationKoinInitializer(
coroutineScope, configuratorAppFeatureTogglesService, firebaseRemoteConfig
).configurationModule)
But it doesn't work...
The error I get on my Logcat:

I am new at dependency injection.
If someone has any idea, I would love.
Thanks.
