Issue with rendering a list of elements in React Native FlatList or using the array mapping method.

Description

Hi,

I’m encountering an issue with the FlatList in React Native (or when using the array mapping method). The rendered items are stacking on top of the previous ones. Below is the code I'm working with. Could you please help me resolve this behavior?

Thank you!

Steps to reproduce

`import { useState } from 'react';
import {
Text,
SafeAreaView,
StyleSheet,
FlatList,
View,
TouchableOpacity,
} from 'react-native';

export default function App() {
const [showOptions, setShowOptions] = useState(false);
const [activeCard, setActiveCard] = useState(null);

return (

<FlatList
data={[0, 1, 2, 3, 4, 5]}
renderItem={({ item, index }) => (

<TouchableOpacity
style={styles.button}
onPress={() => {
setShowOptions(true);
setActiveCard(index);
}}
>
Click me

{showOptions && activeCard === index && (

)}

)}
ItemSeparatorComponent={() => }
contentContainerStyle={styles.listContent}
/>

);
}

const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
backgroundColor: '#ecf0f1',
padding: 8,
},
card: {
height: 100,
width: '100%',
backgroundColor: 'green',
borderRadius: 8,
position: 'relative',
},
button: {
position: 'absolute',
bottom: 10,
right: 10,
},
buttonText: {
color: '#fff',
fontWeight: 'bold',
},
optionsContainer: {
backgroundColor: 'yellow',
borderRadius: 8,
height: 80,
width: '50%',
position: 'absolute',
top: 80,
},
separator: {
height: 20,
},
listContent: {
padding: 20,
paddingBottom: 100,
},
});
`

Inizia con il riproduttore Snack collegato e il componente App fornito, concentrandoti su FlatList, sugli stili di card e optionsContainer e sullo stato che controlla la scheda attiva. Confronta il comportamento sulle piattaforme elencate Android, iOS e Web; il lavoro è completato quando è stato identificato un problema riproducibile di React Native e ne è stata confermata la portata, oppure è stato documentato che è causato dal codice di esempio.
