title: Should I update LiveData to Flow in domain/data layers?
body: <p>I'm working on a big project that uses LiveData on any layer. We only use room to store a two small entities, all of the data is fetched from a service, don't use any cache. Also we don't use coroutines, all is done with LiveData. This project is already in the store (released in 2017) so it is a big stable project.</p>
  <p>I was looking for latest library updates and in many places uses Flow in domain/data layers and then in ViewModel switches to LiveData.</p>
  <p>Should we add coroutines and replace LiveData to Flow in domain/data layers?</p>
