### Installation

Source: https://developer.amazon.com/docs/react-native-vega/0.72/asyncstorage.html

Instructions on how to import and use the legacy AsyncStorage library.

```APIDOC
## Installation

Importing the legacy version of the `AsyncStorage` library:

```javascript
import AsyncStorage from '@amazon-devices/react-native-kepler';
```

**Note** : `AsyncStorage` was recently removed from the mainline React Native libraries. We are working on creating a path to use AsyncStorage more idiomatically. Until this is completed, include `AsyncStorage` in place of the import as follows:

```javascript
const AsyncStorage = require("@amazon-devices/react-native-kepler/Libraries/Storage/AsyncStorage");
```

Be aware that this imports `AsyncStorage` as type `any`, thus any related code will have relaxed type checking.

Persisting data:

```javascript
_storeData = async () => {
  try {
    await AsyncStorage.setItem(
      '@MySuperStore:key',
      'I like to save it.',
    );
  } catch (error) {
    // Error saving data
  }
};
```

Fetching data:

```javascript
_retrieveData = async () => {
  try {
    const value = await AsyncStorage.getItem('TASKS');
    if (value !== null) {
      // We have data!!
      console.log(value);
    }
  } catch (error) {
    // Error retrieving data
  }
};
```
```
