Kotlin Coroutines Expert

Overview

A guide to mastering asynchronous programming with Kotlin Coroutines. Covers advanced topics like structured concurrency, Flow transformations, exception handling, and testing strategies.

When to Use This Skill

• Use when implementing asynchronous operations in Kotlin.
• Use when designing reactive data streams with Flow.
• Use when debugging coroutine cancellations or exceptions.
• Use when writing unit tests for suspending functions or Flows.

Step-by-Step Guide

1. Structured Concurrency

Always launch coroutines within a defined CoroutineScope. Use coroutineScope or supervisorScope to group concurrent tasks.
