What happens if you add new records to a Room database and subscribe to data changes using Flow?

If you add new records to the Room database and subscribe to data changes using Flow, then Flow automatically emits new data when the table being observed is modified. This happens because Room supports reactive streams and tracks changes in the database.

For example, if you have a DAO with a method:

@Query("SELECT * FROM users")
fun getAllUsers(): Flow<List<User>>

and you add a new user through the DAO, the subscriber to this Flow will receive an updated list of users without an additional query or manual data reload.
