+# battery_plus_aurora
+
+The Aurora implementation of [`battery_plus`](https://pub.dev/packages/battery_plus).
+
+## Usage
+
+This package is not an _endorsed_ implementation of `battery_plus`. 
+Therefore, you have to include `battery_plus_aurora` alongside `battery_plus` as dependencies in your `pubspec.yaml` file.
+
+**pubspec.yaml**
+
+```yaml
+dependencies:
+  battery_plus: ^4.0.1
+  battery_plus_aurora:
+    path: # path to folder with plugin
+```
+
+***.dart**
+
+```dart
+// Import package
+import 'package:battery_plus/battery_plus.dart';
+
+// Instantiate it
+var battery = Battery();
+
+// Get current battery level
+final batteryLevel = await _battery.batteryLevel;
+// Get current battery state
+final batteryState = await _battery.batteryState;
+// Check is enable SaveMode
+final isInBatterySaveMode = await _battery.isInBatterySaveMode;
+
+// Be informed when the state (full, charging, discharging) changes
+_battery.onBatteryStateChanged.listen((BatteryState state) {
+  debugPrint(state.toString());
+});
+```
