Idiomatic Kotlin code uses type-safe patterns and safe-call usage for null safety, alongside data class design for immutable value objects. This ensures robust code by defaulting to immutability and enforcing compile-time null checks.

Best practices for Kotlin coroutines and Flow involve applying structured concurrency patterns to manage asynchronous scopes safely. This prevents memory leaks by ensuring child coroutines are scoped to parent lifecycles and properly canceled.

Sealed classes and interfaces create exhaustive, safe type hierarchies in Kotlin, while extension functions add expressive APIs without inheritance. Together they enable compile-time checks for exhaustive when statements and clean domain-specific logic.

Yes, you can refactor existing modules to apply idiomatic Kotlin patterns, focusing on null-safety, immutability, and clear coroutine usage. This transitions legacy code to structured concurrency and expressive DSL builder APIs.

Use Kotlin DSLs and Gradle Kotlin DSL when you need type-safe, expressive configuration APIs. They replace dynamic scripting with strongly-typed builders, improving readability and auto-completion while enforcing immutability and safe-call patterns.

Kotlin code fails to enforce exhaustive type checking when using open or abstract classes instead of sealed hierarchies. Applying sealed classes and interfaces ensures the compiler validates all possible branches in when statements.
