flutter - 如何在 flutter 中检测手机是否已连接到电源

Question

如果手机当前没有充电/连接到电源，我需要显示一个弹出窗口。我如何在 flutter 中实现这一目标？

Answer 1

您可以使用 battery package

它的样子:

// Import package
import 'package:battery/battery.dart';

// Instantiate it
var battery = Battery();

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

var _batteryState;
_battery.onBatteryStateChanged.listen((BatteryState state) {
  _batteryState = state;
  print(_batteryState);
});
