Flutter步数统计插件daily_pedometer的使用

每日步数统计在健康管理中非常重要。本文将介绍如何使用daily_pedometer插件来实现这一功能。该插件目前仅支持Android平台。

权限设置

为了使daily_pedometer插件正常工作，你需要在项目的AndroidManifest.xml文件中添加以下权限：

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM"/>

示例用法

你可以查看示例应用以获得一个完整的例子。下面是一个更通用的例子。记得设置所需的权限，这可能需要你在手机的“设置”中手动允许。

import 'dart:io';
import 'dart:ui';

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:daily_pedometer/daily_pedometer.dart';
import 'package:flutter_background_service/flutter_background_service.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await initializeService();
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = '未知';

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
  }

  // 初始化平台状态
  Future<void> initPlatformState() async {
    final pedometer = DailyPedometer();
    await pedometer.initialize(false);
    setState(() {
      _platformVersion = " ${pedometer.steps} 步";
    });

    pedometer.dailyStepCountStream.listen((event) async {
      setState(() {
        print("stepCountStream : $event");
        _platformVersion = " $event 步";
      });
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('插件示例应用'),
        ),
        body: Center(
          child: Text('运行于: $_platformVersion\n'),
        ),
      ),
    );
  }
}

const notificationChannelId = 'my_foreground';

Future<void> initializeService() async {
  if (!Platform.isAndroid) return;

  final service = FlutterBackgroundService();
  service.invoke("refreshSensorListener");

  // 创建通知通道
  const AndroidNotificationChannel channel = AndroidNotificationChannel(
    notificationChannelId, // id
    '我的前台服务', // 标题
    description: '此通道用于重要的通知。', // 描述
    importance: Importance.low, // 重要性必须为低或更高
  );

      .resolvePlatformSpecificImplementation<AndroidFlutterLocalNotificationsPlugin>()
      ?.createNotificationChannel(channel);

// 启动服务时调用

    });

    service.on('setAsBackground').listen((event) {

    });
  }

  service.on('stopService').listen((event) {
    print("111111 : 3");
    service.stopSelf();
  });

  DailyPedometer pedometer = DailyPedometer();
  service.on("refreshSensorListener").listen((event) async {
    print("refreshSensorListener");
    await pedometer.refreshSensorListener();
  });

  if (service is AndroidServiceInstance) {
    await pedometer.initialize(true);
    print("DailyPedometer 前台服务 ${pedometer.steps}");

    flutterLocalNotificationsPlugin.show(
      888,
      '测试步数',
      '今天的步数: ${pedometer.steps}',
      const NotificationDetails(
