我在我的flutter应用程序中使用了计步器包版本^1.2.0，我注意到它不适用于三星A30等一些设备，我使用的版本不需要任何权限，它在我的设备OPPO F7上工作（使用Android 10）那么问题是什么？
这是代码
StreamSubscription<int> _subscription;
Box<int> stepsBox = Hive.box('steps');
int todaySteps;
@override
void initState() {
super.initState();
startListening();
}
@override
void dispose() {
stopListening();
super.dispose();
}
void startListening() {
_pedometer = Pedometer();
_subscription = _pedometer.pedometerStream.listen(
getTodaySteps,
onError: _onError,
onDone: _onDone,
cancelOnError: true,
);
}
void _onDone() => print("Finished pedometer tracking");
void _onError(error) => print("Flutter Pedometer Error: $error");
Future<int> getTodaySteps(int value) async {
print(value);
int savedStepsCountKey = 999999;
int savedStepsCount = stepsBox.get(savedStepsCountKey, defaultValue: 0);
int todayDayNo = Jiffy(DateTime.now()).dayOfYear;
if (value < savedStepsCount) {
// Upon device reboot, pedometer resets. When this happens, the saved counter must be reset as well.
savedStepsCount = 0;
// persist this value using a package of your choice here
stepsBox.put(savedStepsCountKey, savedStepsCount);
}
// load the last day saved using a package of your choice here
int lastDaySavedKey = 888888;
int lastDaySaved = stepsBox.get(lastDaySavedKey, defaultValue: 0);
// When the day changes, reset the daily steps count
// and Update the last day saved as the day changes.
if (lastDaySaved < todayDayNo) {
lastDaySaved = todayDayNo;
savedStepsCount = value;
stepsBox
..put(lastDaySavedKey, lastDaySaved)
..put(savedStepsCountKey, savedStepsCount);
}
setState(() {
todaySteps = value - savedStepsCount;
});
stepsBox.put(todayDayNo, todaySteps);
return todaySteps; // this is your daily steps value.
}
void stopListening() {
_subscription.cancel();
}
