Firebase and Kotlin: Extensions, Coroutines and Flows
summary
Explains which Java SDK gaps Firebase KTX fills and shows concrete extensions like Firebase.database and snapshot.toObject<T> plus inline reified builders, destructuring helpers and lazy sequences. Demonstrates coroutine integration using kotlinx-coroutines-play-services await on Task to replace nested listeners, proposes using callbackFlow (experimental) for realtime events, and sketches a childrenFlow that emits sealed-class events so five ChildEventListener methods become a single flow collector; mentions type-safe builders and a Crashlytics pair-style helper.
