react-native-sync-storage

It is simple wrapper around AsyncStorage with sync get, set, remove methods and background syncing with AsyncStorage.

Usage

import storage from 'react-native-sync-storage'

...
await storage.init // somewhere where you can wait for loading storage
...
storage.get('property')
storage.set('property', 2333)
storage.remove('property')

Note that set and remove methods return promise which is resolved on syncing with AsyncStorage.
