Overview

Pub Package codecov

A native Dart client implementation of D-Bus.

Accessing a remote object using dart-dbus

The easiest way to get started is to use dart-dbus to generate Dart objects to access existing D-Bus services. Start with a D-Bus interface definition:

<node name="/org/freedesktop/hostname1">
  <interface name="org.freedesktop.hostname1">
    <property name="Hostname" type="s" access="read"/>
  </interface>
</node>

The dart-dbus tool processes this interface to generate a Dart source file:

$ dart-dbus generate-remote-object hostname1.xml -o hostname1.dart

You can then use the generated hostname1.dart to access that remote object:

import 'package:dbus/dbus.dart';
import 'hostname1.dart';

var client = DBusClient.system();
var hostname1 = OrgFreeDesktopHostname1(client, 'org.freedesktop.hostname1');
var hostname = await hostname1.getHostname();
print('hostname: $hostname')
await client.close();

The code generated by dart-dbus may not be the cleanest API you want to expose for your service. It is recommended that you use the generated code as a starting point and then modify it as necessary.

Accessing a remote object manually

You can access remote objects without using dart-dbus if you want. This requires you to handle error cases yourself. The equivalent of the above example is:

import 'package:dbus/dbus.dart';

var client = DBusClient.system();
var object = DBusRemoteObject(client, destination: 'org.freedesktop.hostname1', path: DBusObjectPath('/org/freedesktop/hostname1'));
var hostname = await object.getProperty('org.freedesktop.hostname1', 'Hostname');
print('hostname: ${hostname.toNative()}');
await client.close();

Exporting an object on the bus

import 'package:dbus/dbus.dart';

class TestObject extends DBusObject {
  @override
  DBusObjectPath get path {
    return DBusObjectPath('/com/example/Test');
  }

  @override
  Future<MethodResponse> handleMethodCall(DBusMethodCall methodCall) async {
    if (methodCall.interface == 'com.example.Test') {
      if (methodCall.name == 'Test') {
        return DBusMethodSuccessResponse([DBusString('Hello World!')]);
      } else {
        return DBusMethodErrorResponse.unknownMethod();
      }
    } else {
      return DBusMethodErrorResponse.unknownInterface();
    }
  }
}

var client = DBusClient.session();
await client.registerObject(TestObject());

  • Added required name and path attributes to generated remote object constructor

    Added required name and path attributes to generated remote object constructor

    Right now compilations are failing for any examples on dbus: ^0.6.3 because the remote object constructor has made name and path a required named attribute.

  • [Flatpak] Don't use a hard link to system_bus_socket. Is it possible?

    [Flatpak] Don't use a hard link to system_bus_socket. Is it possible?

    By default, Flatpak apps are isolated from the system bus, the usual option is to explicitly specify the required DBus interface (for example, org.freedesktop.Notifications). All calls on this interface are proxied using xdg-dbus-proxy.

    The problem is that in the case of the dbus package (DBusClient.system()), it's impossible to proxy the system bus in this way, because the system socket path is actually used. Since by default Flatpak apps are isolated from the filesystem and the system bus, we get this exception:

    flutter: SocketException: Connection failed (OS Error: No such file or directory, errno = 2), address = /run/dbus/system_bus_socket, port = 0

    The only solution is to allow access to the system socket (option --socket=system-bus when building the package), but the Flatpak convention considers this permission dangerous https://docs.flatpak.org/en/latest/sandbox-permissions.html#d-bus-access.

    I can't say for sure if a portable way to specify the system bus socket is possible (as in the case of a session socket using XDG paths), but it would be very useful. Or does this require replacing DBusClient.system() with DBusClient.session() in plugins that use it?

  • Signal Streams aren't broadcast by default

    Signal Streams aren't broadcast by default

    Signals streams aren't generated as broadcast by default, this causes a runtime error when the stream is listened to again after a widget is destroyed and rebuilt.

    This is the code that gets generated as of now, but it crashes if a widget is rebuilt and the stream is listened to again

    somesignal = DBusRemoteObjectSignalStream(
            object: this,
            interface: 'com.foo.bar',
            name: 'somesignal',
            signature: DBusSignature('a(ss)'))
        .map((signal) =>
            OrgFreedesktopDBusIntrospectablesomesignal(signal));

    The crashing doesn't occur here since the stream is now built as a broadcast stream and can be listened to multiple times.

    somesignal = DBusRemoteObjectSignalStream(
            object: this,
            interface: 'com.foo.bar',
            name: 'somesignal',
            signature: DBusSignature('a(ss)'))
        .asBroadcastStream()
        .map((signal) =>
            OrgFreedesktopDBusIntrospectablesomesignal(signal));

  • Timeout Exception on Bus Reply.

    Timeout Exception on Bus Reply.

    Hi

    I've been recently bitten by an update in DBus, as now it seems that syncronous DBus calls receive a Timeout from the server, in about 5 seconds.

    The problem happens on Ubuntu 20.04 LTS, with a default install of flutter and dbus 0.5.x. This issue did not happen on dbus 0.3.x

    I receive the following unexpected exception from the server:

    org.freedesktop.Avahi.TimeoutError: TimeoutReached

    As I traced back into my code, this happens when calling the method org.freedesktop.Avahi.Server.ResolveService using the avahi service files. The stack trace is the following:

    00:15 +0: external_api Able to create a discovery without D-Bus complaining

    My test file and entire source code is public at https://github.com/Piero512/bonsoir_linux_dbus

    It seems like DBus is missing a timeout parameter for the method call and now that it parses the error messages correctly, this happens.

  • Unknown DBus data type on Flutter

    Unknown DBus data type on Flutter

    Hi!

    I was trying to interface with the NetworkManger via dbus to provide linux implementation for the flutter connectivity plugin. The source code can be found here. https://github.com/fluttercommunity/firebase_dart_sdk/blob/1dc2373b9524b8a429d6bad32a127eb497fc7b0f/connectivity_linux/lib/connectivity_linux.dart#L81

    Note: This only happens when I run the flutter app. When I run it as a simple dart app everything worked well.

    Thank you.

  • bumped minimum Dart SDK constraint to 2.17

    bumped minimum Dart SDK constraint to 2.17

    0.7.4 declares that it depends xml 6.1.0+, which requires a minimum Dart SDK version of 2.17 but dbus still says the minimum it needs is 2.15. This PR is to address this so that it properly declares the minimum supported Dart SDK

    Two things that came to mind when I noticed this though

    1. Potentially dbus should've published 0.7.4 as 0.8.0
    2. The build actions aren't catching this issue. I'm not that familiar with GitHub but from the workflows I've seen, the containers being referenced point to dart:stable. I suspect this could lead to a version drift of the sorts and the repository may need some way to check that the package still supports the minimum Dart SDK version that it advertises

    Including this package breaks flutter web again

    Version 0.4.0 worked fine but the newest version again makes it impossible to build the flutter project on web.

  • DBusIntrospectAnnotation.toXml() was creating <method> elements

    DBusIntrospectAnnotation.toXml() was creating elements

    Aside from failing to annotate, this bug crashes D-Feet and causes gdbus introspect to report invalid XML. Both D-Feet and gdbus work as expected after this fix is made.

  • Rename file at `bin/dart_dbus.dart` to `bin/dbus.dart` for ease of use.

    Rename file at `bin/dart_dbus.dart` to `bin/dbus.dart` for ease of use.

    If I add some package intended for use as a CLI to a for a Flutter application's dependencies, I can run that using flutter pub run [package_name] [arg1] ... [argN].

    I'd like to suggest renaming this package's file in /bin, and an update to the readme highlighting that it is possible to consume the CLI in the above way for anyone with the Flutter SDK installed.

  • FR: making mocking simple

    FR: making mocking simple

    Something similar to how it is done in flutter with - TestDefaultBinaryMessengerBinding.instance!.defaultBinaryMessenger.setMockMethodCallHandler(_methodChannel, _methodHandler);

    Say for example, consider following dependecny graph my_app -> connectivity_plus -> connectivity_plus_linux -> dbus - know as a app developer - I would want to mock and test certain behaviour based on the result of where it is connected. It is possible to do this with other platform (like Android, iOS, mac which uses Flutter Platform Channels internally), but not with Linux as of now.

    PS: I recently published mock_plugin - to simplify mocking "plugin" library for the end-application developer to mock plugin behaviours - turns out most plugins supporting Linux, uses dbus.dart - I would love to support that too with mock_plugin if there is a way to mock DBus client/channel/messages.
