How can I implement offline storage sync in my React Native app?

You can use libraries like Redux Persist or AsyncStorage to manage offline storage. Would you like a code example?

Yes, please provide a code example using AsyncStorage.

Sure! Here's a simple example:

import AsyncStorage from '@react-native-async-storage/async-storage';

const storeData = async (value) => {
  try {
    await AsyncStorage.setItem('@storage_Key', value);
  } catch (e) {
    // saving error
  }
};

const getData = async () => {
  try {
    const value = await AsyncStorage.getItem('@storage_Key');
    if(value !== null) {
      // value previously stored
    }
  } catch(e) {
    // error reading value
  }
};

This code stores and retrieves data using AsyncStorage. Do you need help with syncing data when the app is back online?

Yes, how can I sync the data when the app comes back online?

You can use the NetInfo library to detect network status changes. When the app goes online, you can trigger a sync function to update your data.
