Flutter插件sahha_flutter的介绍与使用

Sahha SDK为Flutter应用提供了一种方便的方式连接到Sahha API。

文档

Sahha文档提供了详细的安装和使用Sahha SDK的说明。

示例

Sahha Demo App提供了一个方便的方式来尝试Sahha SDK的功能。

示例代码

import 'package:flutter/material.dart';
import 'package:sahha_flutter/sahha_flutter.dart';
import 'package:sahha_flutter_example/Views/AuthenticationView.dart';
import 'package:sahha_flutter_example/Views/BiomarkersView.dart';
import 'package:sahha_flutter_example/Views/HomeView.dart';
import 'package:sahha_flutter_example/Views/ProfileView.dart';
import 'package:sahha_flutter_example/Views/SamplesView.dart';
import 'package:sahha_flutter_example/Views/ScoresView.dart';
import 'package:sahha_flutter_example/Views/SensorPermissionView.dart';
import 'package:sahha_flutter_example/Views/StatsView.dart';
import 'package:sahha_flutter_example/Views/WebView.dart';

void main() {
  runApp(const App());
}

class App extends StatefulWidget {
  const App({Key? key}) : super(key: key);

  [@override](/user/override)
  State<App> createState() => AppState();
}

class AppState extends State<App> {
  [@override](/user/override)
  void initState() {
    super.initState();

    // 使用默认值
    SahhaFlutter.configure(
      environment: SahhaEnvironment.sandbox,
    )
        .then((success) => {debugPrint(success.toString())})
        .catchError((error, stackTrace) => {debugPrint(error.toString())});

    /*
    // 仅适用于Android
    var notificationSettings = {
      'icon': 'Custom Icon',
      'title': 'Custom Title',
      'shortDescription': 'Custom Description'
    };

    // 使用自定义值
    SahhaFlutter.configure(
            environment: SahhaEnvironment.production,
            sensors: [SahhaSensor.device],
            notificationSettings: notificationSettings)
        .then((success) => {debugPrint(success.toString())})
        .catchError((error, stackTrace) => {debugPrint(error.toString())});
    */
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      initialRoute: '/',
      routes: <String, WidgetBuilder>{
        '/': (BuildContext context) => const HomeView(),
        '/authentication': (BuildContext context) => const AuthenticationView(),
        '/profile': (BuildContext context) => const ProfileView(),
        '/permissions': (BuildContext context) => const SensorPermissionView(),
        '/scores': (BuildContext context) => const ScoresView(),
        '/biomarkers': (BuildContext context) => const BiomarkersView(),
        '/stats': (BuildContext context) => const StatsView(),
        '/samples': (BuildContext context) => const SamplesView(),
        '/web': (BuildContext context) => const WebView(),
      },
    );
  }
}

Sahha Flutter 是一个用于健康数据收集和处理的 Flutter 插件,通常用于移动应用中收集用户的健康数据(如步数、心率、睡眠等)。以下是如何探索和使用 sahha_flutter 插件的步骤:

1. 添加依赖

首先,你需要在 pubspec.yaml 文件中添加 sahha_flutter 插件的依赖:

dependencies:
  flutter:
    sdk: flutter
  sahha_flutter: ^1.0.0  # 请使用最新版本

然后运行 flutter pub get 来获取插件。

2. 初始化插件

在使用插件之前,你需要在应用程序启动时初始化 Sahha Flutter。通常可以在 main.dart 文件中进行初始化:

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 初始化 Sahha
  await SahhaFlutter.initialize(
    environment: SahhaEnvironment.sandbox, // 或者 SahhaEnvironment.production
    appId: 'your_app_id', // 从 Sahha 获取的 App ID
    appSecret: 'your_app_secret', // 从 Sahha 获取的 App Secret
  );

  runApp(MyApp());
}

3. 请求权限

为了访问用户的健康数据,你需要请求相应的权限。可以使用 SahhaFlutter.requestPermissions 方法来请求权限:

Future<void> requestPermissions() async {
  try {
    await SahhaFlutter.requestPermissions();
    print('Permissions granted');
  } catch (e) {
    print('Failed to request permissions: $e');
  }
}

4. 获取健康数据

你可以使用 SahhaFlutter.getData 方法来获取用户的健康数据。以下是一个示例:

Future<void> getHealthData() async {
  try {
    // 获取过去 7 天的健康数据
    final healthData = await SahhaFlutter.getData(
      startDate: DateTime.now().subtract(Duration(days: 7)),
      endDate: DateTime.now(),
    );

    print('Health Data: $healthData');
  } catch (e) {
    print('Failed to get health data: $e');
  }
}

5. 处理数据

Sahha Flutter 返回的数据通常是 JSON 格式,你可以根据需要解析和处理这些数据。例如:

void processHealthData(Map<String, dynamic> healthData) {
  if (healthData.containsKey('steps')) {
    final steps = healthData['steps'];
    print('Steps: $steps');
  }

  if (healthData.containsKey('sleep')) {
    final sleep = healthData['sleep'];
    print('Sleep: $sleep');
  }
}

6. 错误处理

在使用 Sahha Flutter 时,可能会遇到各种错误(如权限被拒绝、网络问题等)。确保在使用插件时进行适当的错误处理:

try {
  await SahhaFlutter.getData(startDate: startDate, endDate: endDate);
} catch (e) {
  print('Error: $e');
}
