How can I use AsyncStorage in React Native?

You can use AsyncStorage to store data locally in your React Native app. It allows you to save key-value pairs.

Can you give me some code examples?

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 shows how to store and retrieve data using AsyncStorage.

What types of data can I store?

You can store strings, numbers, and JSON objects (as strings) in AsyncStorage. Just remember to stringify objects before storing.

Are there any limitations I should be aware of?

Yes, AsyncStorage is not suitable for large amounts of data. It's best for small pieces of data like user preferences or settings.
