Hi,
I want to have my database and repository properties into my Application class. It's working but I wonder if this is okey and clean way of doing this ?
Maybe i will use dagger in the future but not now.

class MyApp : Application() {
    val database: AppDatabase by lazy { AppDatabase.getInstance(this) }
    val dataRepository: DataRepository by lazy { DataRepository(database.documentDao) }
}

I think this is a great way to expose singleton application scope without adding in a framework.

If the dependency is application scoped might be worth throwing it in MyApp companion object for ergonomics

Thanks for the advice 🙂, cleaner than before

But for the database I use this, how can I pass application instance (for context) in the companion object ?

[Brendan Weinstein]

class App : Application {
  companion object {
    lateinit var appInstance: App

    val dateabase: AppDatabase by lazy { AppDatabase.getInstance(appInstance) }
  }

  onCreate {
    appInstance = this
  }
}
