print(battery.batteryLevel);

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

Suggestions

  • Use constrained dependencies.

    The pubspec.yaml contains 1 dependency without version constraints. Specify version ranges for the following dependencies: flutter.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.
