kotlin-coroutines-flows

Structured concurrency in Kotlin organizes asynchronous work to prevent leaks by enforcing parent-child relationships between coroutines. This ensures tasks are properly cancelled and scoped within Android and Kotlin Multiplatform applications.

Use StateFlow for stateful data streams requiring a single updated state, and SharedFlow for broadcasting multiple values to multiple collectors. Both manage reactive data streams in Kotlin but serve distinct state-holding and event broadcasting purposes.

Testing Kotlin coroutines and flows requires deterministic scheduling to verify UI state and asynchronous behavior predictably. This approach controls virtual time and execution order to validate flow emissions and cancellation logic accurately.

Kotlin Multiplatform supports parallel task orchestration using coroutines across Android, JVM, and native platforms. This enables concurrent data loading and responsive UI development while maintaining structured concurrency and error handling.

Handling errors in Kotlin Flow operators involves using specific operators to catch exceptions and manage reactive data stream failures. This ensures robust asynchronous work by handling errors gracefully without crashing the application.

Android coroutine leaks occur when asynchronous work is not properly scoped to the lifecycle. Applying structured concurrency patterns scopes tasks to appropriate lifecycles, ensuring automatic cancellation when navigation destroys the view.
