How do I use AsyncStorage with async/await in React Native?

You can use AsyncStorage to store data in React Native. To use it with async/await, first import AsyncStorage from '@react-native-async-storage/async-storage'. Then, you can create an async function to set and get data.

Can you show me an example of setting and getting data?

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) {
      return value;
    }
  } catch(e) {
    // error reading value
  }
};

This code sets a value and retrieves it later.

What types of data can I store in AsyncStorage?

You can store strings, but you can also store objects by converting them to strings using JSON.stringify() before saving, and then parsing them back with JSON.parse() when retrieving.

Is there a limit to how much data I can store?

Yes, AsyncStorage has a limit of around 6MB on iOS and 2MB on Android, but this can vary based on the device.
