Kotlin Coroutines

Overview

This skill provides expert guidance on Kotlin Coroutines, covering structured concurrency, scopes, Dispatchers (including main-safe suspend and dispatcher injection), cancellation (including withTimeout semantics), exception handling (CoroutineExceptionHandler, launch vs async), Channels, Flow (cold vs hot, collectLatest, SharedFlow configuration, blocking in flow {}), lifecycle-aware collection on Android, and testing (virtual time, setMain/resetMain). Use this skill to help developers write safe, maintainable concurrent code aligned with Kotlin 1.9+/2.0+ conventions and official best practices.
