Flutter网络速度测试插件flutter_speedtest的使用

flutter_speedtest 是一个用于检查互联网速度的 Flutter 插件。本文将详细介绍如何在 Flutter 项目中使用 flutter_speedtest 插件进行网络速度测试。

Getting Started

Add Dependency

首先，在 pubspec.yaml 文件中添加 flutter_speedtest 依赖：

dependencies:
  flutter_speedtest: ^0.0.2+2

然后运行 flutter pub get 命令来安装依赖。

Usage

初始化 FlutterSpeedtest

在 Dart 代码中导入 flutter_speedtest 包，并初始化 FlutterSpeedtest 对象。你可以指定服务器的 URL 和路径。

import 'package:flutter_speedtest/flutter_speedtest.dart';

final _speedtest = FlutterSpeedtest(
  baseUrl: 'http://speedtest.jaosing.com:8080', // 你的服务器 URL
  pathDownload: '/download', 
  pathUpload: '/upload',
  pathResponseTime: '/ping',
);

执行速度测试

使用 _speedtest.getDataspeedtest 方法来执行速度测试。你可以通过回调函数来处理下载、上传、响应时间和错误信息。

_speedtest.getDataspeedtest(
  downloadOnProgress: ((percent, transferRate) {
    // 在 UI 中更新下载进度和传输速率
  }),
  uploadOnProgress: ((percent, transferRate) {
    // 在 UI 中更新上传进度和传输速率
  }),
  progressResponse: ((responseTime, jitter) {
    // 在 UI 中更新响应时间和抖动
  }),
  onError: ((errorMessage) {
    // 处理错误信息
  }),
  onDone: () => debugPrint('done'),
);

完整示例代码

以下是一个完整的示例代码，展示了如何在 Flutter 应用中使用 flutter_speedtest 插件进行网络速度测试。

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

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

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

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

class _MyHomePageState extends State<MyHomePage> {
  final _speedtest = FlutterSpeedtest(
    baseUrl: 'https://speedtest.globalxtreme.net:8080',
    pathDownload: '/download',
    pathUpload: '/upload',
    pathResponseTime: '/ping',
  );

  double _progressDownload = 0;
  double _progressUpload = 0;
  int _ping = 0;
  int _jitter = 0;

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Flutter Speedtest'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('Download: $_progressDownload Mbps'),
            Text('Upload: $_progressUpload Mbps'),
            Text('Ping: $_ping ms'),
            Text('Jitter: $_jitter ms'),
            ElevatedButton(
              onPressed: () {
                _speedtest.getDataspeedtest(
                  downloadOnProgress: ((percent, transferRate) {
                    setState(() {
                      _progressDownload = transferRate;
                    });
                  }),
                  uploadOnProgress: ((percent, transferRate) {
                    setState(() {
                      _progressUpload = transferRate;
                    });
                  }),
                  progressResponse: ((responseTime, jitter) {
                    setState(() {
                      _ping = responseTime;
                      _jitter = jitter;
                    });
                  }),
                  onError: ((errorMessage) {
                    // 处理错误信息
                    debugPrint(errorMessage);
                  }),
                  onDone: () => debugPrint('done'),
                );
              },
              child: const Text('Test Speed'),
            ),
          ],
        ),
      ),
    );
  }
