How to Handle Exceptions in Kotlin Flows

A practical guide to handling exceptions in Kotlin's Flow API. Covers three main approaches: catching exceptions locally inside operator lambdas (try-catch within the flow), wrapping the collector in a try-catch block (which abandons the flow on exception), and using the catch operator to intercept upstream exceptions and optionally emit values in response. Key points include: exceptions propagate downstream to the collector, the catch operator only sees upstream exceptions, cancellation exceptions should not be swallowed, and retry functions exist for re-running flows after exceptions.
