Collecting flows in a lifecycle-aware manner
summary
Explains how to stop and start Flow collection based on Android lifecycle by using repeatOnLifecycle, flowWithLifecycle, and collectAsStateWithLifecycle; repeatOnLifecycle spawns a coroutine at a given Lifecycle.State (commonly STARTED), cancels it when falling below that state and only returns when the lifecycle is destroyed; flowWithLifecycle is implemented with repeatOnLifecycle plus callbackFlow; collectAsStateWithLifecycle (alpha) wraps produceState for Compose so emissions update Compose state only while visible.
