Getting Started

To use this plugin, add sstp_flutter as a dependency in your pubspec.yaml file.

dependencies:
  sstp_flutter: ^version

Then, run flutter pub get to install the dependency.

Example

import 'package:sstp_flutter/sstp_flutter.dart';

void main() async {
  SstpFlutter sstpFlutter = SstpFlutter();
  var cert_dir = "";

  // Take VPN permission
  await sstpFlutter.takePermission();

  // Save server data
  await sstpFlutter.saveServerData(server: SSTPServer(host: 'example.com',port:443 , username: 'user', password: 'password',verifyHostName : false, useTrustedCert: false, sslVersion: SSLVersions.DEFAULT, showDisconnectOnNotification: true, notificationText: "Notification Text Holder"));

  // Opens files and then returns selected directory path
  cert_dir = await sstpFlutterPlugin.addCertificate();

  // Connect to SSTP VPN
  await sstpFlutter.connectVpn();

  // Monitor connection status
  sstpFlutter.onResult(
    onConnectedResult: (ConnectionTraffic traffic) {
      print('Connected - Download Traffic: ${traffic.downloadTraffic}, Upload Traffic: ${traffic.uploadTraffic}');
    },
    onConnectingResult: () {
      print('Connecting...');
    },
    onDisconnectedResult: () {
      print('Disconnected');
    },
    onError: () {
      print('Error occurred');
    },
  );

  // Monitor connection Duration
  StreamBuilder(
  initialData: const Duration(),
  stream: sstpFlutterPlugin.timer,
  builder: (context, timer) {
    return timer.hasData
        ? Text("connection time : ${timer.data}")
        : const Text("connection time :no Data");
   })

  // Disconnect from SSTP VPN
  await sstpFlutter.disconnect();

  // Get installed apps
  List<InstalledAppInfo> installedApps = await sstpFlutter.getInstalledApps();
  print('Installed Apps: $installedApps');

  // Get allowed apps
  List<String> allowedApps = await sstpFlutter.getAllowedApps();
  print('Allowed Apps: $allowedApps');

  // Add apps to allowed apps
  await sstpFlutter.addToAllowedApps(packages: ['com.example.app']);

  // Enable DNS
  await sstpFlutter.enableDns(DNS: '8.8.8.8');

  // Disable DNS
  await sstpFlutter.disableDNS();

  // Enable proxy
  await sstpFlutter.enableProxy(proxy: SSTPProxy(host: 'proxy.example.com', port: 8080));

  // Disable proxy
  await sstpFlutter.disableProxy();

  // Check last connection status
  UtilKeys status = await sstpFlutter.checkLastConnectionStatus();
  print('Last Connection Status: $status');
}
