# shared_preferences_aurora
|
||
|
|
|
||
|
|
The Aurora implementation of [`shared_preferences`][https://pub.dev/packages/shared_preferences].
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
This package is not an _endorsed_ implementation of `shared_preferences`.
|
||
|
|
Therefore, you have to include `path_provider_aurora` alongside `shared_preferences` as dependencies in your `pubspec.yaml` file.
|
||
|
|
|
||
|
|
**pubspec.yaml**
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
dependencies:
|
||
|
|
shared_preferences: ^2.1.1
|
||
|
|
shared_preferences_aurora: ^0.0.0 # @todo Not published
|
||
|
|
```
|
||
|
|
|
||
|
|
***.dart**
|
||
|
|
|
||
|
|
```dart
|
||
|
|
import 'package:shared_preferences/shared_preferences.dart';
|
||
|
|
|
||
|
|
final SharedPreferences prefs = await SharedPreferences.getInstance();
|
||
|
|
|
||
|
|
// Save an integer value to 'counter' key.
|
||
|
|
await prefs.setInt('counter', 10);
|
||
|
|
// Save an boolean value to 'repeat' key.
|
||
|
|
await prefs.setBool('repeat', true);
|
||
|
|
// Save an double value to 'decimal' key.
|
||
|
|
await prefs.setDouble('decimal', 1.5);
|
||
|
|
// Save an String value to 'action' key.
|
||
|
|
await prefs.setString('action', 'Start');
|
||
|
|
// Save an list of strings to 'items' key.
|
||
|
|
await prefs.setStringList('items', <String>['Earth', 'Moon', 'Sun']);
|
||
|
|
|
||
|
|
// Try reading data from the 'counter' key. If it doesn't exist, returns null.
|
||
|
|
final int? counter = prefs.getInt('counter');
|
||
|
|
// Try reading data from the 'repeat' key. If it doesn't exist, returns null.
|
||
|
|
final bool? repeat = prefs.getBool('repeat');
|
||
|
|
// Try reading data from the 'decimal' key. If it doesn't exist, returns null.
|
||
|
|
final double? decimal = prefs.getDouble('decimal');
|
||
|
|
// Try reading data from the 'action' key. If it doesn't exist, returns null.
|
||
|
|
final String? action = prefs.getString('action');
|
||
|
|
// Try reading data from the 'items' key. If it doesn't exist, returns null.
|
||
|
|
final List<String>? items = prefs.getStringList('items');
|
||
|
|
```
