Facing issue with React Native Flip Card functionality not working properly when trying to flip

I am currently working on developing a flip card game using GestureFlipView for the flip card animation. My goal is to display these flip cards in a 3X3 grid by utilizing components from React Native. However, I have encountered an issue where the cards are not flipping as expected and displaying unpredictable behavior. Only the last card seems to be functioning correctly while the others exhibit erratic behavior.

If you'd like to check out my project on Github, here's the repository link: https://github.com/akhilomar/React-Native-Number-Game

Here is a snapshot of the CardScreen component: https://i.sstatic.net/Cliww.png

Card Component Code:

import {View, Text, SafeAreaView, TouchableOpacity} from 'react-native';
import GestureFlipView from 'react-native-gesture-flip-card';

const Cards = (props) => {
    // code snippet

}

export default Cards;

Card List Component Code:

import React from 'react';
import {SafeAreaView, View, FlatList, Dimensions, StyleSheet } from 'react-native';
import Cards from './Cards';

const CardScreen = () => {
    // code snippet

}

export default CardScreen;

Make sure to utilize the ref properly. Additional information can be found here

const Cards = (props) => {
  //begin by defining the ref
  const flipViewRef = React.useRef();


  //use it in onPress like this
  <TouchableOpacity onPress = {() => {
        flipViewRef.current.flipRight() 
        ...     
 }} >

  //assign it in GestureFlipView like this
  <GestureFlipView ref={flipViewRef} />
  


}

The main issue causing difficulties is the utilization of a this reference inside a functional component. As detailed here, the interpretation of this will depend on how the function is invoked and could potentially be undefined. A more dependable method to utilize this is within a class context. In the case of React, this entails using a class component instead of a functional one, which is what's currently being utilized. For further information on function and class components, you can refer here.

It's also worth considering if employing a FlatList is suitable in this scenario. Typically, this component is employed to enhance performance for rendering extensive lists. Instead of implementing a FlatList, it might be advisable to opt for a simpler alternative like utilizing a series of View elements to display the cards. Below is a comprehensive example derived from your code:

// Code snippet provided as an example
import React, { useState } from 'react';
import { View, Dimensions, StyleSheet, Text, TouchableOpacity } from 'react-native';
import GestureFlipView from 'react-native-gesture-flip-card';

// Remaining code defining Card and related components
.
.
.

export default CardScreen;
