 The UI Kitten team started actively using React Navigation alpha and we're proud to announce the full compatibility to the new React Navigation API. In this guide, we won't consider how to implement all of the boilerplate stuff like auth screens. Instead, we will learn how to navigate between screens using Drawer, Bottom Tabs, Top Tabs, and Stack navigators to build a TODO-App. Furthermore, we'll demonstrate using React Navigation with UI Kitten components.

 Traditionally, we have written our navigators in JavaScript for greater customizability. It fits a lot of use cases, but sometimes you want the exact native feel and the performance of native navigation. Now, we have added a new native stack navigator that uses native navigation primitives for navigation using the [`react-native-screens`](https://github.com/kmagiera/react-native-screens) library. Under the hood, it just uses native components which might be obvious choice for native development and might be a good pick in the most cases.
