1. SearchableFlatList

API

Props	Description	Data Type	isRequired
`data`	Data for the FlatList	`Array`	:white_check_mark:
`searchTerm`	Searching Term being input by the user. Typically this will be a state variable bound to a text input	`String`	:white_check_mark:
`searchAttribute`	Attribute to be searched in case of array of objects. This will be empty in case of a simple array data	`String`	:x:
`ignoreCase`	Case sensitive / Case insensitive search. By default this will be set to true	`Boolean`	:x:

By default the SearchableFlatList also inherits all the props of a React Native FlatList. You could use virtually any props you would with a FlatList.

Usage

import { SearchableFlatList } from "react-native-searchable-list";

 <SearchableFlatList
          data={this.state.flatListData}
          searchTerm={this.state.searchTerm}
          searchAttribute={this.state.searchAttribute}
          ignoreCase={true}
          renderItem={({ item }) => <Text>{item.name}</Text>}
          keyExtractor={item => item.id}
        />
