Operation Flow
summary
Covers concrete Kotlin Coroutines Flow operators and patterns: builders (flow, flowOf, callbackFlow/channelFlow — callbackFlow requires awaitClose), intermediates (filter, map, buffer, debounce, onStart/onEach/onCompletion, retryWhen/catch, flowOn, transform is the powerful primitive), combinators (zip vs combine, combine reuses last value), flatMap variants (flatMapLatest cancels previous), reduce/scan, hot flows (SharedFlow vs StateFlow replays last value), prefer emit over tryEmit, and testing hot flows with Turbine.
