Summary: This tutorial will explore Kotlin's Expect and Actual Declarations, highlighting their importance in Kotlin development. We will cover the basic syntax, defining Expect declarations and implementing Actual declarations, working with platform-specific code, using Expect and Actual in multiplatform projects, advanced features like conditional Expect declarations and overriding Expect declarations, best practices for organizing Expect and Actual declarations, and real-world use cases such as cross-platform networking and shared data models.

Introduction​

What are Expect and Actual Declarations?​

Expect and Actual Declarations are a feature in Kotlin that allows developers to write common code that can be used across multiple platforms, while still providing platform-specific implementations when necessary. With Expect and Actual Declarations, developers can define interfaces or classes with expected behavior, and then provide actual implementations for each platform.

In this tutorial, we will explore Kotlin's Expect and Actual declarations for native libraries. Expect and Actual declarations allow us to write platform-specific code in a shared module, making it possible to write multiplatform applications with Kotlin. We will learn how to set up Kotlin Native libraries, define Expect declarations, implement Actual declarations, and test and debug Kotlin Native libraries.
