reactnative save data asyncstorage

Guys I call the getdatas into useEffect but still it's not saving and give this error, [TypeError: getCountry is not a function. (In 'getCountry(ulke)', 'getCountry' is "2")]

Im just started the reactnative, please explain easily thanks.

(Im selecting datas into picker btw)

const fetchPray = async county => {
    const url4 = '' + county;
    console.log(url4);
    fetch(url4)
        .then(response => response.json())
        .then(pray => {
            setPray(pray);
            let index = pray.findIndex(d => d.MiladiTarihKisa === date);
            let selectData = pray[index];
            setVakitGunes(selectData.Gunes);
            setVakitImsak(selectData.Imsak);
            setVakitOgle(selectData.Ogle);
            setVakitIkindi(selectData.Ikindi);
            setVakitAksam(selectData.Aksam);
            setVakitYatsi(selectData.Yatsi);
            setGunTurkce(selectData.MiladiTarihUzun);


            AsyncStorage.setItem('ulke', getCountry);
            AsyncStorage.setItem('il', getCity);
            AsyncStorage.setItem('ilce', getCounty);
            AsyncStorage.setItem('gunes', vakitGunes);
            AsyncStorage.setItem('imsak', vakitImsak);
            AsyncStorage.setItem('ogle', vakitOgle);
            AsyncStorage.setItem('ikindi', vakitIkindi);
            AsyncStorage.setItem('aksam', vakitAksam);
            AsyncStorage.setItem('yatsi', vakitYatsi);
            AsyncStorage.setItem('tarih', gunTurkce);
        }).catch(error => console.log(error))
        .finally(() => setLoading4(false));
};
