const data = [
  { id: 1, value: 'Item 1' },
  { id: 2, value: 'Item 2' },
  { id: 3, value: 'Item 3' },
];

const App = () => {
  const [selectedValue, setSelectedValue] = useState('');

  const renderItem = ({ item }) => (
    <TouchableOpacity onPress={() => onItemPress(item)}>
      <Text>{item.value}</Text>
    </TouchableOpacity>
  );

  const onItemPress = (item) => {
    setSelectedValue(item.value);
  };

  return (
    <FlatList
      data={data}
      renderItem={renderItem}
      keyExtractor={(item) => item.id.toString()}
    />
  );
};

export default App;
