Flutter app failure after non clean snapcraft build

snapcraft

Hey, we have a flutter app packaged with snap that runs on ubutu core, recently we introduced a new library for talking with dbus , but we ran into a problem, as below,

2024-10-29T13:48:18Z salto-ssi-outdoor.daemon[25697]: Starting app
2024-10-29T13:48:18Z salto-ssi-outdoor.daemon[25757]: **
2024-10-29T13:48:18Z salto-ssi-outdoor.daemon[25757]: GLib-GObject:ERROR:../../../gobject/gtype.c:2808:g_type_register_static: assertion failed: (static_quark_type_flags)
2024-10-29T13:48:18Z salto-ssi-outdoor.daemon[25757]: Bail out! GLib-GObject:ERROR:../../../gobject/gtype.c:2808:g_type_register_static: assertion failed: (static_quark_type_flags)

but if we do a clean snapcraft build its not happening anymore. But this solve issue temporarily, so next non-clean build it will crash again.

the way we access the DBUS is

void _setupWatchdog() {
  Timer.periodic(const Duration(seconds: 10), (_) {
    var client = DBusClient.system();
    var object = DBusRemoteObject(client, name: 'org.ssi.app.intercom.outdoor.watchdog', path: DBusObjectPath('/org/ssi/app/intercom/outdoor/watchdog'));
    object.callMethod('org.ssi.app.intercom.outdoor.watchdog', 'Feed', []);
    client.close();
  });
}

    environment:
      PYTHONPATH: $SNAP/usr/lib/python3/dist-packages:$SNAP/bin:$PYTHONPATH

    plugs:
      - devicedata
      - network
....
plugs:
  dbus-watchdog-object-client:
    bus: system
    interface: dbus
    name: org.ssi.app.intercom.outdoor.watchdog

slots:
  dbus-watchdog-object-service:
    interface: dbus
    bus: system
    name: org.ssi.app.intercom.outdoor.watchdog

I was thinking maybe snapcraft somehow associate build with dbus object registration, so that a clean build helps.

Any idea, how to approach for a solution?
