Flutter ping

by

To ping a server or a website using Flutter, you can make use of the `ping_discover_network` package. This package allows you to send ICMP echo requests (commonly known as pings) to a specified host and receive the corresponding responses. Here’s how you can use this package to ping a server in Flutter:

  1. Add the `ping_discover_network` package to your pubspec.yaml file:

    dependencies:
  ping_discover_network: ^0.3.1
  2. Import the necessary classes in your Flutter code:

    import 'package:ping_discover_network/ping_discover_network.dart';
  3. Use the `NetworkAnalyzer` class to send ping requests and handle the responses:

    void pingServer(String ipAddress) {
  NetworkAnalyzer.discover2(ipAddress).then((List devices) {
    if (devices.isNotEmpty) {
      NetworkAddress server = devices[0];
      print('Server is online - IP address: ${server.ip}');
    } else {
      print('Server is offline.');
    }
  });
}

    In the example above, we are using the `discover2` method of the `NetworkAnalyzer` class to send a ping request to the specified IP address. The `discover2` method returns a list of `NetworkAddress` objects representing the devices that responded to the ping request. We can then check if the list is empty to determine whether the server is online or offline.

  4. Call the `pingServer` method with the desired IP address to ping the server:

    pingServer('192.168.0.1');

    In this example, we are pinging the server with the IP address `192.168.0.1`. You can replace this IP address with the one you want to ping.

By using the `ping_discover_network` package in Flutter, you can easily send ping requests to servers and handle their responses. This can be useful in scenarios where you want to check if a server is online or measure its response time.
