Try it out

You can try it out with Exponent here

Example

Look at the example folder to run the expo app locally.

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 :tada:
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 :rocket:
