react-native-complete-flatlist

Extended version of react native flat list with many built in function such as search, pull to refresh, no data available message if empty row

Caution:

renderItem props return data and index parameters data parameter returns a single element in data array. But if search text is not empty, data parameter will return new structure of JSON object (in order to render highlighted text in jsx). This might break your logic. Therefore, if you want to access original structure of your data, it will be under data.cleanData. Remember, data.cleanData only exist if search text is not empty (user is searching)

Usage :

import React, { Component } from 'react';
import { View, Text, Image, Platform, StatusBar } from 'react-native';
import CompleteFlatList from 'react-native-complete-flatlist';


const data = [
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Syah', status: 'Active', time: '9:14 PM', date: '1 Dec 2018' },
  { name: 'Izzat', status: 'Active', time: '8:15 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  { name: 'Fattah', status: 'Active', time: '8:10 PM', date: '1 Jan 2018' },
  {
    name: 'Muhyiddeen',
    status: 'Blocked',
    time: '10:10 PM',
    date: '9 Feb 2018',
  },
];

class App extends Component {
  cell = (data,index) => {
    const item = data.cleanData ? data.cleanData : data

    console.log(data.cleanData)
    console.log('data.cleanData will be not null if search bar is not empty. caution, data without search is not same like data with search due to implement the highlight component. data.cleanData is equal to data')

    console.log('this is index number : '+index)

    console.log(item+' this is original data')

    return <Text>{data.name}</Text>;
  }

  render() {
    const { navigation } = this.props;
    return (
      <CompleteFlatList
      searchKey={['name', 'status', 'time', 'date']}
      highlightColor="yellow"
      pullToRefreshCallback={() => {
        alert('refreshing');
      }}
      data={data}
      ref={c => this.completeFlatList = c}
      renderSeparator={null}
      renderItem={this.cell}
      onEndReached={() => console.log("reach end")}
      onEndReachedThreshold={0}
    />
    );
  }
}

Prop	Type	Description	Default	Required
