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');
}
