const Tabs = () => {

  const navigation = useNavigation();

  const [open, setOpen] = useState(false);
  const [value, setValue] = useState(null);
  const objects = [
    { label: 'Ayarlar', value: 'ayarlar' },
    { label: 'Yardım', value: 'yardim' },
    { label: 'Çıkış Yap', value: 'cikisYap' }
  ];
  
    const Tab = createBottomTabNavigator();
    const handleDropdownChange = (merchandise) => {
      if (merchandise.worth === 'cikisYap') {
        authCtx.logout();
        setOpen(false);
      }
    };
  
    const renderDropDownButton = () => (
      <TouchableOpacity onPress={() => setOpen(!open)}>
        <Picture
          supply={require('../../belongings/profile-default.jpg')}
          fashion={kinds.customButton}
        />
      </TouchableOpacity>

                    paddingRight: 10,
                    flexDirection: 'row',
                    alignItems: 'middle',
                  }}
                >
                  <Picture
