Going with the Flow - Using Coroutines 1.3.x
summary
Shows concrete migration patterns: Retrofit 2.6.0 uses suspend service methods, Flow is Flow stable in Kotlin 1.3.0, and channels change semantics. Compares channel types (rendezvous, unlimited, array, conflated), demonstrates broadcast channel deadlock and why conflated broadcast channel behaves like LiveData for multi-subscriber state. Presents a working alternative: a broadcast-style Flow that uses sendBlocking/awaitClose to start on first subscriber and stop on last, and notes Lifecycle 2.2 RC2 scope helpers (launchWhenResumed) for lifecycle-aware coroutines.
