Async into var

[Frostswing]

This is a very silly question, but for some reason i have found no answer to the past 3 days...

All i want to do is to put data from async storage and put it into a var...

For example my app could store the user's requestend language and reuse this data on the next app launch...

Using simple:
value= AsyncStorage.getItem('chosenLanguage')
wouldn't work since i get the promise instead of the data, this part i understand.

After a short check i saw that since its an async function i should use await like this:
var value=await AsyncStorage.getItem('@APP:chosenLanguage') ;
But then i get :

Unexpected identifier '_asyncStorage'. Expected ')' to end an argument list.
ERROR

I tried using:

 const getData = async (callback) => {
  var value,collect;
   try {
     value= await AsyncStorage.getItem('chosenLanguage').then(
       (avalue) => {
          collect=avalue;
       });
  
     } catch(e) {
     // error reading value
   }
   callback(collect) ;
 }

But it seems that while i can read collect and use it inside the getData function, i cannot use this data outside of the function...
Using a return to the avalue\collect variables gets me the promise instead of the data....

Can anyone help me please?
Thanks!

anyone has a solution?

Use Jotai which integrates with AsyncStorage

[Frostswing]

So to use AsyncStorage i need another library?

What is the main usage of this library then?
To be integrated inside usestates?

[ansh]

No, you can use a useEffect and also make it happen. AsyncStorage, is, like the name says, async. You want a sync solution. Jotai is the easiest one. You can also set it up using useEffect. The solution should be trivial so I won’t include the code here.

tbh i just wanted local storage for startup values, like chosen app language ect...
I guess ill try this or the sync-storage library on the community.

Thank you!

You can do that within a useEffect, just wait for the loading to finish below hiding the SplashScreen.
