What are some examples of using async storage in my app?

Async storage is commonly used for saving user preferences, session data, and caching API responses. Would you like specific code examples?

Yes, please provide a code example for saving user preferences.

Sure! Here's a simple example in React Native:

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

const storeUserPreference = async (key, value) => {
  try {
    await AsyncStorage.setItem(key, value);
  } catch (e) {
    // saving error
  }
};

This function saves a user preference under a specified key.

How do I retrieve that stored preference?

You can retrieve it using the following code:

const getUserPreference = async (key) => {
  try {
    const value = await AsyncStorage.getItem(key);
    return value !== null ? value : null;
  } catch (e) {
    // error reading value
  }
};

This function fetches the stored value for the given key.
