Modeling Retrofit Responses With Sealed Classes and Coroutines

In the exploration of managing Retrofit API responses using Kotlin, the article outlines how to employ Coroutines and Sealed classes to streamline application architecture by reducing code complexity. It emphasizes the use of sealed classes to encapsulate possible API response scenarios, such as success, error, and exceptions, enabling more robust error handling and clear communication across application layers. The handleApi function is introduced to manage API calls and exceptions, while custom Retrofit CallAdapters and CallAdapterFactory are demonstrated to further simplify API response handling. Additionally, it discusses the advantages of using Kotlin extensions for the NetworkResult class and introduces the Sandwich library as an alternative solution for efficient response handling. The article also touches on leveraging Kotlin's standard Result class for comprehensive response management, rounding out its guidance with practical code examples and resource links for deeper engagement.
