ubuntu_session 0.0.2

Native Dart client library to access the GNOME Session Manager

ubuntu_session.dart

Native Dart client library to access Ubuntu desktop session managers

Simplified API

The simplified API provides a small set of methods common among different Ubuntu desktop managers. It will try to detect the current desktop environment and invoke the methods provided by the respective session manager.

Currently provided methods:

• logout()
• reboot()
• shutdown()

If the desktop environment is unknwon (or the API is not implemented yet..) it will use systemd-logind as a fallback. Warning - the fallback API will not show a confirmation dialog for logout(), reboot() or shutdown(). You can use fallback: false to disable the fallback.

import 'package:ubuntu_session/ubuntu_session.dart';

void main() {
  final session = UbuntuSession();
  print('Detected desktop environment: ${session.desktop}');
  session.reboot();
}

GNOME Session Manager

import 'package:dbus/dbus.dart';
import 'package:ubuntu_session/ubuntu_session.dart';

void main() async {
  final manager = GnomeSessionManager();
  await manager.connect();
  try {
    await manager.reboot();
  } on DBusMethodResponseException catch (e) {
    print('Error: $e');
  }
  await manager.close();
}
