Description

Why Learn KMP?Kotlin Multiplatform is growing fast. JetBrains and Google are both investing heavily in it.Companies like Netflix, Forbes, McDonald's, and many others already have production apps written in KMP.Demand for KMP developers is increasing — most Android jobs nowadays mention KMP as a plus or outright demand knowledge of it.Unlike Flutter or React Native, KMP lets you use Kotlin— so you don’t need to to learn a new language. In fact, if you’re an Android engineer - you already know 90% of everything that you need to start using it.By learning KMP, you will: - Increase your job prospects and compensation.- Become a more versatile developer who understands how many different platforms work.- Will be able to develop for virtually all platforms with Kotlin.Who is This Course For?Android Developers who want to expand into cross-platform developmentMobile Engineers familiar with Android who are looking for a native alternative to Flutter or React NativeDevelopers working on existing Android apps who want to introduce KMP graduallyWhat you'll learn:Project Setup for Android + iOSExpect / Actual mechanismRegular + Intermediate source sets. How to reduce code duplication among different platforms. Efficient code structuring around targets. Code sharing vs platform-specific code. KMP Compilation processAnd exercises, of course
