Go with the Flow 🌊
summary
Kotlin Flow is a Reactive Streams implementation built on coroutines that is cold, null-safe, and multiplatform. It claims backpressure is handled by suspending rather than special operators, offers asFlow and callbackFlow for incremental migration from RxJava, and preserves context with a single operator for dispatcher control. Migration guidance includes team safeguards and adapter libraries for Rx1/2, and testing uses coroutine scopes like runBlocking with take/first conversions to lists for easy assertions.
