SNetwork Connection Checker

Screenshots

Configs

`failedPingCount` -> a failed ping up to this parameter is considered a lost connection

`reTryDuration` -> throws a ping during this duration

`pingTimeout` -> If there is no response to the ping in this time, it is considered unsuccessful

`urls` -> links to ping, As default, the first element of the list is taken

SNetworkConnectionChecker.instance.selectedIp.setState(SIpModel("Google 1", "8.8.8.8", 53));

  SNetworkConnectionChecker.instance.setConfig(
    failedPingCount: 2,
    pingTimeout: const Duration(seconds: 2),
    reTryDuration: const Duration(seconds: 3),
    urls: [
      SIpModel("Google 1", "8.8.8.8", 53),
      SIpModel("Google 2", "8.8.4.4", 53),
    ],
  );

Usage

Check if you have internet connection

  var hasConnection = await SNetworkConnectionChecker.instance.hasConnection();

  print("Has connection $hasConnection");
  runApp(const FullScreenWarningWithOpacity());

Listen to the status of your internet connection

void main() async {
    // IMPORTANT
    // You can call anywhere you want
    SNetworkConnectionChecker.instance.startListen();
    runApp(const FullScreenWarningWithOpacity());
}
// ..........

SNetworkConnectionChecker.instance.isConnected.listen(
      (value) {
        // true connected, false not connected, null loading
        print("Connection status changed $value");
      },
    );

/// .........
