What does the KotlinJsonAdapterFactory() function do in relation to Moshi?

The KotlinJsonAdapterFactory() function is specifically designed to enhance the functionality of Moshi, a popular JSON library for Android and other platforms. By providing support for Kotlin's specific features, such as non-nullable types and data classes, this function allows Moshi to effectively serialize and deserialize Kotlin objects without the need for extra boilerplate code or configurations.

This integration means that properties of Kotlin data classes can be directly mapped to JSON fields with minimal effort, ensuring seamless interaction between Kotlin code and JSON data formats. Additionally, the KotlinJsonAdapterFactory can handle certain corner cases that are relevant to Kotlin's type system that other JSON adapters might not accommodate. Therefore, this function plays a crucial role in leveraging Kotlin's language features, making it easier and more efficient to work with JSON in a Kotlin environment.
