Flutter如何检查电池健康状况

dependencies:
  battery: ^2.0.0

import 'package:battery/battery.dart';

Battery battery = Battery();
BatteryState batteryState;
int batteryLevel;

// 获取电池状态
battery.batteryState.then((state) {
  setState(() {
    batteryState = state;
  });
});

// 获取电池电量百分比
battery.batteryLevel.then((level) {
  setState(() {
    batteryLevel = level;
  });
});

// 获取电池健康状况
String getBatteryHealth() {
  switch (batteryState) {
    case BatteryState.full:
      return '健康';
    case BatteryState.discharging:
      return '正常';
    case BatteryState.charging:
      return '正常';
    case BatteryState.unknown:
      return '未知';
    default:
      return '未知';
  }
}
