Messing around with Room for the first time, and wondering what you all think about this usage:

viewModelScope.launch {
customerRepo.customer(customerUid) // Returns a `Flow<Customer>`
  .combine(controllerRepo.controllersForCustomer(customerUid)) { customer, controllers ->
    CustomerWithControllers(customer, controllers)
  }
  .collect { customerWithControllers ->
    internalState.value = State.Loaded(customerWithControllers)
  }
}

This works just fine, but when I go to delete a

customer

, the deletion cascades to the

controllers

and what you end up with is a new

CustomerWithControllers

with empty controllers because the

customer

Flow

last emission was the customer that was just deleted. I solved this by holding onto the

Job

returned by

launch

, and when I go delete a customer, I basically cancel that

Job

, delete the customer, and then execute a function that checks for the existence of any customer and if one doesn't exist, brings the user to a FTUX screen. Is this a decent way of handling this? It'd be nice if

Room

had some way to emit an

Empty

token or something to indicate the table is empty 🤔

Hmm can't you just do filter a , for only valid CustomerWithControllers ? Or perhaps a custom channelFlow, that only calls

controllerRepo.controllersForCustomer(customerUid))? upon a valid return of customerRepo.customer(customerUid)
