hello when you map db to domain objects, which are then passed to the ui say list of domain foos now you want to go to foo detail screen to view a foo what do you pass in as argument? foo id and then query db + map to domain Foo in the foo detail screen? if so, what if the app is mixed local + remote data, i.e. from foo list screens are fetched from remote, you dont have them in db, so, cannot query them... have domain foo implement Parcelable? 🥵
