The following code structure is implemented in App.js because the application needs to be completely initialized before making any API requests.

import React, { useState, useEffect } from 'react';
import { AppState, View } from 'react-native';
import Navigation from './Navigation'; // Import your Navigation component

/**
 * Main application component.
 * Renders the navigation component based on the current app state.
 */
const App = () => {
// State to hold the current app state
const [appState, setAppState] = useState(AppState.currentState);

useEffect(() => {
// Function to handle changes in the app state.
    		const handleAppStateChange = (nextAppState) => {
                setAppState(nextAppState);
            };

// Subscribe to app state changes
const subscription = AppState.addEventListener('change',handleAppStateChange);

// Unsubscribe when the component unmounts
return () => {
subscription.remove();
};
}, []); // Empty dependency array to run effect only once

return (
<View>
{/* Render the navigation component only when app state is 'active' */}
{appState === 'active' && <Navigation />}
    </View>
);
};

export default App;
