A Flutter plugin to access various information about the battery of the device the app is running on.

Usage #

To use this plugin, add battery as a dependency in your pubspec.yaml file.

Example #

import 'package:battery/battery.dart';

// Instantiate it
var battery = new Battery();

// Access current battery level
print(battery.batteryLevel);

// Be informed when the state (full, charging, discharging) changes
_battery.onBatteryStateChanged.listen((BatteryState state) {
  // Do something with new state
});
