I want to use Async storage. Each time I call without the async function like this
FunctionLogin = () =>{ //other methods here ........ }
and this does not have await anywhere, it saves to the database but when i use let email = AsyncStorage.getItem(’email’); to call it back, it does not return anything like the email just [Object object] is what i see
how do I resolve this
the fetch method to save to async storage looks like this
`FunctionLogin = async () =>{
//navigation.replace('VirtualAccountPage');
let item = {email, password,phone};
fetch('https://xxxxxxxxxxxxxxxx/api/sign-up', {
method: 'POST',
mode: 'cors',
headers: {
Accept: 'application/json',
'Content-type': 'application/json',
},
body: JSON.stringify(item),
})
.then(response => response.json())
.then(responseJson =>{
if (responseJson.message === 'User created Successfully') {
await AsyncStorage.setItem('email', email);
await AsyncStorage.setItem('phone', phone);
alert('I am Registered');
navigation.replace('VirtualAccountPage');
} else {
alert(responseJson);
}
})
.catch(error => {
console.error(error);
});
}`
the function to call it back, so it can be used as persistence looks thus
` FunctionUserDetails = () => {
let email = AsyncStorage.getItem('email');
let phone = AsyncStorage.getItem('telephone');
//navigation.replace('Dashboard');
alert(email);
};`
How do i get this to work?
I want to be able to save data locally using async storage so i can be able to persist the data on some other screens etc. I tried several things to see if It could work as expected, i do not get to see it work as i want.
