Final Results
The modified app/build.gradle
should resemble:
plugins {

}
android {
compileSdk 31

applicationId "com.commonsware.todo"

Our new RosterMotor
should look like:
package com.commonsware.todo
import androidx.lifecycle.ViewModel
class RosterMotor(private val repo: ToDoRepository) : ViewModel() {
val items = repo.items
}
ToDoApp
should resemble:
package com.commonsware.todo
import android.app.Application
import org.koin.android.ext.koin.androidLogger
import org.koin.androidx.viewmodel.dsl.viewModel
import org.koin.core.context.startKoin
import org.koin.dsl.module
class ToDoApp : Application() {
private val koinModule = module {
single { ToDoRepository() }
viewModel { RosterMotor(get()) }
}
override fun onCreate() {
super.onCreate()
startKoin {
androidLogger()
modules(koinModule)
}
}
}
And the altered RosterListFragment
should look like:
package com.commonsware.todo
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.fragment.app.Fragment
import org.koin.androidx.viewmodel.ext.android.viewModel
class RosterListFragment : Fragment() {
private val motor: RosterMotor by viewModel()
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.todo_roster, container, false)
}
}
