Fueled Reactive apps with Asynchronous Flow and StateFlow to sync with the UI

on YouTube ↗51m

" summary

Shows step‑by‑step migration from RxJava to Kotlin coroutines, Flow and StateFlow using Retrofit/OkHttp, Room and kotlinx‑coroutines with rxinterop so Java and Kotlin coexist; deepest layers migrate first, then repos expose flows collected by scopes with scope+supervisorJob for structured cancellation; replaces callbacks with StateFlow exposes UI state and uses channelFlow with awaitClose for view events; demo app (search tweets) compiles and runs, enabling gradual removal of RxJava and fewer memory leaks.
