Kotlin Multiplatform by Tutorials

The best book to teach you how to share code across platforms using Kotlin Multiplatform. You’ll gain the foundation of creating user interfaces using native UI toolkits and then writing common code for serialization, networking and persistence. You’ll also learn how dependency injection, testing and different architectures fit in with Kotlin Multiplatform so that you build maintainable and scalable apps for the real world.

Kotlin Coroutines by Tutorials

The importance of concurrency is discovered quite early on by people who start with Android development. Android is inherently asynchronous and event-driven, with strict requirements as to on which thread certain things can happen.

Add to this the often-cumbersome Java callback interfaces, and you will be trapped in spaghetti code pretty quickly (aptly termed as “Callback Hell”). No matter how many coding patterns you use to avoid that, you will have to encounter the state change across multiple threads in one way or the other.

The only way to create a responsive app is by leaving the UI thread as free as possible, letting all the hard work be done asynchronously by background threads.

Kotlin Coroutines by Tutorials will teach you the techniques you need to solve common programming problems using asynchronous programming.

Functional Programming in Kotlin by Tutorials

Functional programming is a powerful paradigm for building your applications. This book will teach you the fundamentals of functional programming in a practical, hands-on way, while showing you how you can safely handle errors and state changes in your programs.
