Flutter实时位置追踪插件hypertrack_plugin的使用
Flutter HyperTrack SDK
HyperTrack allows you to add live location tracking to your mobile app. Live location is made available along with ongoing activity, tracking controls, and tracking outage with reasons.
Flutter HyperTrack SDK is a wrapper around native iOS and Android SDKs that allows integration of HyperTrack into Flutter apps. For detailed instructions on how to get started, check this Guide.
Installation
To add the hypertrack_plugin
to your Flutter project, run the following command:
flutter pub add hypertrack_plugin
Sample Code
You can find a quickstart Flutter app example here.
Wrapper API Documentation
For more details about the API, refer to the Wrapper API Documentation.
Requirements
Android
- Gradle version 6.7.1+
- compileSdkVersion 31+
iOS
- iOS version 12.4+

Complete Example Demo
Below is a simple example demonstrating how to use the hypertrack_plugin
for real-time location tracking in a Flutter application.
main.dart
import 'package:flutter/material.dart';
import 'package:hypertrack_plugin/hypertrack.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'HyperTrack Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'HyperTrack Real-Time Location Tracking'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
String _deviceId = '';
@override
void initState() {
super.initState();
_initializeHyperTrack();
}
Future<void> _initializeHyperTrack() async {
// Initialize HyperTrack with your Publishable Key
await HyperTrack.initialize('YOUR_PUBLISHABLE_KEY');
// Get Device ID
var device = await HyperTrack.getDeviceId();
setState(() {
_deviceId = device;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'Your Device ID:',
),
Text(
'$_deviceId',
style: Theme.of(context).textTheme.headline4,
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: () async {
// Start tracking
await HyperTrack.startTracking();
},
tooltip: 'Start Tracking',
child: Icon(Icons.play_arrow),
),
);
}
}
Notes:
- Replace
'YOUR_PUBLISHABLE_KEY'
with your actual HyperTrack publishable key. - Ensure you have added necessary permissions in
AndroidManifest.xml
andInfo.plist
for accessing location services.
This demo provides a basic setup to start using HyperTrack’s real-time location tracking features in a Flutter application. For more advanced usage, refer to the official documentation and sample code provided by HyperTrack.

当然,以下是如何在Flutter应用中使用hypertrack_plugin
进行实时位置追踪的代码示例。这个插件允许你集成Hypertrack的SDK,以实现实时位置追踪功能。
首先,确保你已经在pubspec.yaml
文件中添加了hypertrack_plugin
依赖:
dependencies:
flutter:
sdk: flutter
hypertrack_plugin: ^最新版本号 # 请替换为实际的最新版本号
然后,运行flutter pub get
来安装依赖。
接下来,你需要按照Hypertrack的文档完成SDK的初始化设置,包括获取API密钥和配置应用权限(如位置权限)。
初始化Hypertrack
在你的Flutter应用的入口文件(通常是main.dart
)中,进行Hypertrack的初始化:
import 'package:flutter/material.dart';
import 'package:hypertrack_plugin/hypertrack_plugin.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
// 初始化Hypertrack
await HypertrackPlugin.init(
apiKey: 'YOUR_HYPERTRACK_API_KEY', // 替换为你的Hypertrack API密钥
debug: true, // 设置为true用于调试,生产环境应设置为false
);
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(),
);
}
}
开始位置追踪
在你的主页面或需要开始位置追踪的地方,调用Hypertrack的startTracking
方法:
import 'package:flutter/material.dart';
import 'package:hypertrack_plugin/hypertrack_plugin.dart';
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
void initState() {
super.initState();
// 开始位置追踪
_startTracking();
}
Future<void> _startTracking() async {
try {
await HypertrackPlugin.startTracking(
userId: 'USER_ID', // 替换为用户的唯一标识符
metadata: {'key': 'value'}, // 可选的元数据
);
print('Tracking started successfully');
} catch (e) {
print('Error starting tracking: $e');
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Real-time Location Tracking'),
),
body: Center(
child: Text('Tracking is started'),
),
floatingActionButton: FloatingActionButton(
onPressed: () async {
// 停止位置追踪
await HypertrackPlugin.stopTracking();
print('Tracking stopped');
},
tooltip: 'Stop Tracking',
child: Icon(Icons.stop),
),
);
}
}
处理位置更新
为了处理位置更新,你可以监听Hypertrack提供的位置流。这通常需要在你的应用中设置一个监听器来接收位置更新。
import 'package:flutter/material.dart';
import 'package:hypertrack_plugin/hypertrack_plugin.dart';
class _MyHomePageState extends State<MyHomePage> {
StreamSubscription<Map<String, dynamic>>? _locationSubscription;
@override
void initState() {
super.initState();
_startTracking();
// 监听位置更新
_locationSubscription = HypertrackPlugin.onLocationUpdate().listen((location) {
print('Location update: $location');
// 在这里处理位置更新,例如更新UI
});
}
@override
void dispose() {
// 取消订阅位置更新流
_locationSubscription?.cancel();
_locationSubscription = null;
// 停止位置追踪(可选,如果已经在其他地方停止)
// HypertrackPlugin.stopTracking();
super.dispose();
}
// ... 其他代码,如_startTracking方法
}
这个示例展示了如何在Flutter应用中使用hypertrack_plugin
进行实时位置追踪的基本步骤。请确保你遵循Hypertrack的文档和最佳实践,以充分利用其功能并确保应用的稳定性和安全性。
