Functional Kotlin

It's a sample app used to learn Functional programming with Kotlin.

Kotlin has many nice features as a modern language, and to enhance all its power, Arrow is the perfect companion: "Λrrow is a library for Typed Functional Programming in Kotlin"

Brief overview

This side project is the transformation of the previous written in Java side project: FlickrFeed with RxJava 2 & DI.

However, it is 100% Kotlin without any DI on this side project, I believe is not necessary at all for such a simple project, nor RxJava 2 on behalf of Kotlin coroutines for asynchronous tasks.

SDK support

Support SDKs from 21 to 27
