2. Import Package


import 'package:battery_plus/battery_plus.dart';

3. Create Battery Instance


Battery battery = Battery();

Create an instance of the Battery class to access battery-related functionalities.

4. Get Battery Level


int batteryLevel = await battery.batteryLevel;

Use battery.batteryLevel to get the current battery level as a percentage.

5. Check Battery Status


BatteryState batteryState = await battery.batteryState;

Use battery.batteryState to get the current battery status, such as charging, discharging, full, etc.

6. Subscribe to Battery Changes


StreamSubscription batterySubscription =
    battery.onBatteryStateChanged.listen((BatteryState state) {
  // Handle battery state changes
});

Subscribe to changes in battery state using onBatteryStateChanged and handle the state changes accordingly.

7. Dispose Subscription (Optional)


batterySubscription.cancel();

Dispose the subscription when no longer needed to free up resources.
