I’m trying to store and get data that I fetch from an API. The user is supposed to get a token on the login screen, and the token will be shown in an Alert dialog on home screen when the user press a button. But the token is not shown in the Alert dialog. the token is shown after I reload(not refresh the app. I used Live Server extension) the screen three times.
Login.js
const _userLogin = () => { fetch(URLs._login, { method: "POST", headers, body, }) }).then((response) => response.json()) .then((result) => { if(result.message !== "Unauthorized / Access Token Expired" && result.message !== "The given data was invalid."){ storeData(result.access_token, result.token_type); navigation.navigate('HomeScreen'); } else { Alert.alert("Error", result.message); } }); }; const storeData = async (accessToken, tokenType) => { try { await AsyncStorage.setItem('@access_token', accessToken); await AsyncStorage.setItem('@token_type', tokenType); await AsyncStorage.setItem('@user_auth', tokenType + " " + accessToken); } catch (e) { console.log(e); } }
Home.js [UPDATE]
const [inputs, setInputs] = React.useState({ userToken: '', userPointsBalance: '', expiringOn: '', }); useEffect (() => { _dashboard(); }) const getToken = async () => { inputs.userToken = await AsyncStorage.getItem('@user_auth'); } const _dashboard = () => { getToken(); fetch(URLs._dashboard, { method: "GET", headers: { 'Authorization': inputs.userToken, 'Content-Type': 'application/json', }, }).then((response) => response.json()) .then(async (result) => { storeData(result.code, result.name, result.member_name, result.user_points_balance, result.expiring_on, result.status, result.token_id); getData(); }); }; const storeData = async (code, name, memberName, userPointsBalance, expiringOn, status, tokenId) => { try { await AsyncStorage.setItem('@user_points_balance', userPointsBalance.toString()); await AsyncStorage.setItem('@expiring_on', expiringOn.toString()); } catch (e) { console.log(e); } } const getData = async () => { const userPointsBalance = await AsyncStorage.getItem('@user_points_balance'); const expiringOn = await AsyncStorage.getItem('@expiring_on'); setInputs({userPointsBalance: userPointsBalance, expiringOn: expiringOn}); } return ( <Text>{inputs.expiringOn}<Text> )

Answer
i hope it works
.then(async(result) => { if(result.message !== "Unauthorized / Access Token Expired" && result.message !== "The given data was invalid."){ await storeData(result.access_token, result.token_type) .then(res=> navigation.navigate('HomeScreen') ) } else { Alert.alert("Error", result.message); } });
