</AutocompleteDropdownContextProvider>

import the package

import { AutocompleteDropdown } from 'react-native-autocomplete-dropdown';

Dataset item format

dataSet property must be an array of objects or null. Object required keys are:

{
    id: 'some uniq string id',
    title: 'list item title'
}

Example with local Dataset

const [selectedItem, setSelectedItem] = useState(null);

<AutocompleteDropdown
  clearOnFocus={false}
  closeOnBlur={true}
  closeOnSubmit={false}
  initialValue={{ id: '2' }} // or just '2'
  onSelectItem={setSelectedItem}
  dataSet={[
    { id: '1', title: 'Alpha' },
    { id: '2', title: 'Beta' },
    { id: '3', title: 'Gamma' },
  ]}
/>;

Example with remote requested Dataset

import React, { memo, useCallback, useRef, useState } from 'react'
import { Button, Dimensions, Text, View, Platform } from 'react-native'
import { AutocompleteDropdown } from 'react-native-autocomplete-dropdown'

export const RemoteDataSetExample2 = memo(() => {
  const [loading, setLoading] = useState(false)
  const [suggestionsList, setSuggestionsList] = useState(null)
  const [selectedItem, setSelectedItem] = useState(null)
  const dropdownController = useRef(null)

  const searchRef = useRef(null)

  const getSuggestions = useCallback(async q => {
    const filterToken = q.toLowerCase()
    console.log('getSuggestions', q)
    if (typeof q !== 'string' || q.length < 3) {
      setSuggestionsList(null)
      return
    }
    setLoading(true)
    const response = await fetch('https://jsonplaceholder.typicode.com/posts')
    const items = await response.json()
    const suggestions = items
      .filter(item => item.title.toLowerCase().includes(filterToken))
      .map(item => ({
        id: item.id,
        title: item.title,
      }))
    setSuggestionsList(suggestions)
    setLoading(false)
  }, [])

  const onClearPress = useCallback(() => {
    setSuggestionsList(null)
  }, [])

  const onOpenSuggestionsList = useCallback(isOpened => {}, [])

  return (
