Develop Your App with Lots of "Flow"
summary
Builds a musical quiz app that plays intervals to help memorize references, implemented with Kotlin coroutines Flow and StateFlow and SharedFlow to publish view state and UI events, following an MVI unidirectional pipeline. Maps UI events → actions → processor (side effects, DB, network) → reducer → new view state, compares Flow to RxJava, finds single‑event (toast) tricky and suggests channels or clearing state. App is work in progress but the Flow-based pipeline works for ordered async UI events.
