Motivation

Currently there are a couple packages that provide a similar parallax Scrollview component (here and here) although both of them are not maintained and wasn't exactly what I was looking for.

So I challenged myself to create a Parallax ScrollView component (using react-native-parallax-view as a base) with

1. Sticky NavBar Header 🎉
2. An awesome default profile component that just works out of the box (<ParallaxScrollView />)
3. Flexible and comprehensive API to use the ScrollView component for any use case.

aka it's a (Parallax) ScrollView component for React Native that we truly deserve 🚀
