On Linux, the tray icon is a StatusNotifierItem published by nativeapi, and its Id property is hard-coded (src/platform/linux/tray_icon_linux.cpp):
if (g_strcmp0(property_name, "Id") == 0)
return g_variant_new_string("nativeapi-tray");The SNI spec wants Id to be a name that is unique to the application and stable across sessions. Hosts use it to remember per-item settings (hidden/shown, order), and some show it to the user: niri shows it as the hover tooltip. Right now every nativeapi app reports the same nativeapi-tray, so hosts can't tell apps apart, and a user's choice for one app applies to all of them.
Proposal:
- Default the
Id to something app-specific and stable, for example the application id (g_application_get_application_id() of the default GApplication, which is what Flutter's Linux runner sets from APPLICATION_ID), falling back to the executable name. Add a per-icon suffix only when an app has several tray icons.
- Let apps set it explicitly:
TrayIcon::SetId(std::string) (or a constructor argument), set before the item is registered, since Id must not change afterwards. Expose it in the bindings (Flutter: TrayIcon.id).
- On macOS and Windows it can be a no-op, or map to
NSStatusItem.autosaveName on macOS, which serves the same purpose (remembering position/visibility).
