react-native-flatlist-alphabet


A simple React Native component that takes an array of data and renders a SectionList with alphabetically sorted data.

!Alt text

This package_uses the array of objects data-structure.

``javascript
const data = [{...}, {...}, {...}, ...]
`

For _react-native-flatlist-alphabet_, the data does not need to be pre-formatted and sorted before use. The component handles all this logic internally.

`bash
npm install react-native-flatlist-alphabet
`

or with yarn:

`bash
yard add react-native-flatlist-alphabet
`

Usage

`javascript
import AlphabetList from "react-native-flatlist-alphabet";
`

$3

`javascript
data={YourData}
renderItem={YourRenderItemFunction}
renderSectionHeader={YourRenderSectionHeaderFunction}
getItemHeight={YourItemHeight}
sectionHeaderHeight={YourHeaderHeight}
indexLetterColor={ColorOfTheIndexSidebarLetters}
/>
`

YourData should be provided as an Array of objects, with each object item having both a valueand a key.

`javascript
const YourData = [
{
value: string, // determines which alphabet section to place the object in
key: string // used as the key in the keyExtractor for SectionList
... // your other properties
},
...
]
`
