[Solved] Warning: AsyncStorage has been extracted from react-native core and will be removed in a future release.

Solved by:

1. Change import {AsyncStorage} from 'react-native'; to import {AsyncStorage} from '@react-native-async-storage';
2. Check from your node-modules dependencies that using import {AsyncStorage} from 'react-native'; In my case, I used “redux-persist”: “5.10.0” that using asycnstorage from react-native in my store.js file:

import storage from ‘redux-persist/lib/storage’;
const persistConfig = {
   key: ‘root’,
   storage,
   blacklist: [],
};

so i changed this to:

import AsyncStorage from ‘@react-native-async-storage/async-storage’;
const persistConfig = {
   key: ‘root’,
   storage: AsyncStorage,
   blacklist: [],
};

FIXED !!!
