The main issue I am faced with is centering my search component horizontally and vertically using flex. The code works perfectly on webview, but it is not centered vertically on the native view. I am currently using Expo, which provides various options for viewing the app. To resolve this, I am including the App.tsx and Search.tsx files below. To center a component horizontally and vertically using flex, apply the styles "flex: 1", "alignItems: center" and "justifyContent: center" to the parent container. In this case, the parent container is "View" with the style of "styles.container". On the web view, this styling seems to work fine, but on the native view, the vertical centering is not working as expected. Here is the App.tsx code:

 
import React from 'react';
import { View } from 'react-native';
import Search from './components/Search';

const styles: any = {
  container:{
    flex: 1,
    margin: 20,
    alignItems: 'center',
    justifyContent: 'center'
  }
}
const App = () => {

  return (
    
      
    
  );
};

export default App;

Here is the Search.tsx code:

import React, { useState, useEffect } from 'react';
import { View, TextInput, FlatList, Text } from 'react-native';

const Search = () => {
  const [searchTerm, setSearchTerm] = useState('');
  const [results, setResults] = useState([]);

  useEffect(() => {
    let timerId:any = null;
    if (searchTerm.length >= 2) {
      clearTimeout(timerId);
      timerId = setTimeout(() => {
        fetch(`http://localhost:8080/search/${searchTerm}`)
          .then((response) => response.json())
          .then((data) => setResults(data.results))
          .catch((error) => console.error(error));
      }, 500);
    } else {
      setResults([]);
    }

    return () => clearTimeout(timerId);
  }, [searchTerm]);

  return (
    
       setSearchTerm(text)}
        placeholder="Search"
      />
       item}
        renderItem={({ item }) => (
          {item}
        )}
      />
    
  );
};

export default Search;

I hope this helps! Let me know if you have any further questions.
