RN-Header

Can Use the header as a stand alone header, or a scroll away header.

You must have react-native-vector-icons installed and linked for this to display icons on the header. Can also display text on the sides of header

Uses Font Awesome icons as the icon source

npm install react-native-vector-icons --save
react-native link react-native-vector-icons
npm install rn-header --save
 

• To use as a scroll away header takes a little work to set up.
• import Animated from react-native
• Add an Animated.Value to the constructor. Need a scrollY so the Header can respond properly
• Can use with Listview or ScrollView.
• SET UP THE ONSCROLL PROP TO MATCH THIS EXAMPLE
• If you don't use scrollEventThrottle you're gonna have a bad time...mmmm-kay??
• just copy/paste this example and you'll get the hang of it 🤓
• When using as a scroll away header, wrap whatever content you want to stay within the <Header> </Header> tags. When using as a stand alone Header, just use as <Header/>

If you do not want the header to scroll away, do not supply the header with the scrollY
