Flutter网络流量统计插件traffic_stats的使用

Flutter网络流量统计插件traffic_stats的使用

插件介绍

traffic_stats 是一个简单的的Flutter插件，用于监控应用程序中的网络速度（(下载和上传)。它提供了实时的网络流量统计数据，并且可以分别显示下载和上传的速度（单位为千字节每秒 (kbps)。

特性

• 实时监控：实时监控网络流量。
• 单独值：提供下载和上传速度的独立值（单位：kbps）。
• 易于集成：轻松地将插件与您的Flutter UI集成以显示网络速度信息。

安装

1. 添加依赖到pubspec.yaml文件中：

dependencies:
  traffic_stats: 

1. 安装包：

$ flutter pub get

1. 导入包：

import 'package:traffic_stats/traffic_stats.dart';

使用示例

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

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

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

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Network Speed Monitor',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const NetworkSpeedPage(),
    );
  }
}

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

  [@override](/user/override)
  NetworkSpeedPageState createState() => NetworkSpeedPageState();
}

class NetworkSpeedPageState extends State<NetworkSpeedPage> {
  final NetworkSpeedService _networkSpeedService = NetworkSpeedService();
  late Stream<NetworkSpeedData> _speedStream;
  late NetworkSpeedData _currentSpeed;

  [@override](/user/override)
  void initState() {
    super.initState();
    _networkSpeedService.init(); // 初始化服务
    _speedStream = _networkSpeedService.speedStream;
    _currentSpeed = NetworkSpeedData(downloadSpeed: 0, uploadSpeed: 0);

    // 监听流并用新数据更新状态
    _speedStream.listen((speedData) {
      setState(() {
        _currentSpeed = speedData;
      });
    });
  }

  [@override](/user/override)
  void dispose() {
    _networkSpeedService.dispose(); // 当组件销毁时，释放资源
    super.dispose();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Network Speed Monitor'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              'Download Speed: ${_currentSpeed.downloadSpeed} Kbps',
              style: const TextStyle(fontSize: 20),
            ),
            const SizedBox(height: 16),
            Text(
              'Upload Speed: ${_currentSpeed.uploadSpeed} Kbps',
              style: const TextStyle(fontSize: 20),
            ),
          ],
        ),
      ),
    );
  }
}

示例代码

import 'package:flutter/material.dart';
import 'package:traffic_stats/traffic_stats.dart'; // 更新此导入路径至实际包路径

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Network Speed Monitor',
      theme: ThemeData(

      ),
      home: NetworkSpeedPage(),
    );
  }
}

  [@override](/user/override)
  _NetworkSpeedPageState createState() => _NetworkSpeedPageState();

    _speedStream.listen((speedData) {
      setState(() {
