Unidirectional Data Flow with...
summary
Claims a concrete Unidirectional Data Flow implemented with Android Architecture Components and Kotlin Coroutines (Channels/Actors): a View → ViewModel → Store → Reducer pipeline that returns immutable view states via LiveData. Store runs in its own CoroutineScope on IO, dispatches states on Main, and uses Either to separate success vs failure streams, channels (produce/receive) for multi-step updates, and fold to test accumulated channel outputs. Implementation targets MixTiles app and reports improved testability and scalability.
