Add the plugin to your pubspec.yaml file:

dependencies:

flutter_speed_test_plus: ^latest_version

Basic Usage

import 'package:flutter_speed_test_plus/flutter_speed_test_plus.dart';

void startSpeedTest() {
  final speedTest = FlutterInternetSpeedTest();
  speedTest.startTesting(
    useFastApi: true, // true by default, uses Fast.com API
    onStarted: () {
      print('Speed test started');
    },
    onCompleted: (TestResult download, TestResult upload) {
      print('Download Speed: ${download.speed} Mbps');
      print('Upload Speed: ${upload.speed} Mbps');
    },
    onProgress: (double percent, TestResult data) {
      print('Progress: $percent%');
    },
    onError: (String errorMessage, String speedTestError) {
      print('Error: $errorMessage');
    },
    onDownloadComplete: (TestResult data) {
      print('Download complete: ${data.speed} Mbps');
    },
    onUploadComplete: (TestResult data) {
      print('Upload complete: ${data.speed} Mbps');
    },
    onCancel: () {
      print('Test cancelled');
    },
  );
}

Advanced Usage

You can customize the test by providing your own server URLs and file size:

import 'package:flutter_speed_test_plus/flutter_speed_test_plus.dart';

void startCustomSpeedTest() {
  final speedTest = FlutterInternetSpeedTest();
  speedTest.startTesting(
    useFastApi: false, // Use custom server instead of Fast.com
    downloadTestServer: 'https://your-download-server.com/testfile', // Custom download server URL
    uploadTestServer: 'https://your-upload-server.com/upload', // Custom upload server URL
    fileSize: 20, // File size in MB for testing (default is 10MB)
    onStarted: () {
      print('Speed test started');
    },
    onCompleted: (TestResult download, TestResult upload) {
      print('Download Speed: ${download.speed} Mbps');
      print('Upload Speed: ${upload.speed} Mbps');
    },
    onProgress: (double percent, TestResult data) {
      print('Progress: $percent%');
    },
    onError: (String errorMessage, String speedTestError) {
      print('Error: $errorMessage');
    },
    onDownloadComplete: (TestResult data) {
      print('Download complete: ${data.speed} Mbps');
    },
    onUploadComplete: (TestResult data) {
      print('Upload complete: ${data.speed} Mbps');
    },
    onCancel: () {
      print('Test cancelled');
    },
  );
}

Configuration Options

Default Server URLs

If no custom server URLs are provided, the plugin will use the following default URLs:

• Download Servers: https://fast.com/

• Upload Servers: https://fast.com/

Custom Options

You can override the default settings with custom values:

• Server URLs: Specify your own downloadTestServer and uploadTestServer.
• File Size: Set the fileSize parameter (in MB) for the test. The default is 10 MB.

Callback Descriptions

Here’s a list of all available callbacks for handling test progress and results:

• onStarted: Called when the speed test starts.
• onCompleted: Called with final download and upload speeds.
• onProgress: Called with the test progress percentage and intermediate results.
• onError: Called if an error occurs during the test.
• onDefaultServerSelectionInProgress: Triggered during server selection (when useFastApi is true).
• onDefaultServerSelectionDone: Triggered when server selection is complete (when useFastApi is true).
• onDownloadComplete: Called when the download test is completed.
• onUploadComplete: Called when the upload test is completed.
• onCancel: Triggered if the test is cancelled.

Supported Platforms

• iOS
• Android
