Missing locale causes `DateFormat` to throw an exception

[Snubletunge]

When I choose an app in the Ubuntu App Center, it won't show details about the app, or the information images just flash for a moment.

** (snap-store:17779): WARNING **: 18:43:14.817: atk-bridge: get_device_events_reply: unknown signature flutter: Another exception was thrown: Instance of 'DiagnosticsProperty'

I have tried to reinstall Ubuntu, but the issue persist.

Thanks for the report - could you provide the log files from $HOME/snap/snap-store/current/.local/share/snap-store and the output of glxinfo -B to help diagnose possible rendering issues?

[Feichtmeier]

This looks like the error widget in release mode :) (a widget that flutter draws when something went wrong) Could you start snap-store from the terminal and provide any errors / outputs / exceptions here?

[Snubletunge]

Here is the error message when running the snap from terminal:

Please try to not load it. flutter: INFO snap-store: Logging to /home/chello/snap/snap-store/1134/.local/share/snap-store/snap-store.log flutter: INFO appstream: Unsupported locale: nn.

OK, so the locale nn (Norwegian nynorsk) that I am using, is crashing this, changed to the locale nb (Norwegian bokmål) and the store works as it should.

Still seems something is off when I run it from Terminal:

$ snap run snap-store Gtk-Message: 19:46:14.151: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it. flutter: INFO snap-store: Logging to /home/chello/snap/snap-store/1134/.local/share/snap-store/snap-store.log flutter: INFO appstream: Unsupported locale: nb_NO. Defaulting to "en".

** (snap-store:5753): WARNING **: 19:46:39.348: atk-bridge: get_device_events_reply: unknown signature

[d-loose]

Thanks for providing those additional details. The issue seems to be that, even though the proper localization delegates for nn_NO and others are provided by ubuntu_localizations, they're only available if the corresponding locale is listed in the supportedLocales for the MaterialApp. With our current setup that requires the existence of the respective .arb file. I'm adding nn_NO through weblate to see if that solves the problem for this specific locale. I'll keep this issue open though, since we should find a proper solution for all cases.

[mguinhos]

Also having this problem.

[d-loose]

Also having this problem.

Which locale are you using? Are you seeing a similar error message when running snap-store from the terminal?

[mguinhos]

@d-loose

flutter: INFO appstream: Unsupported locale: und. Defaulting to "en".

its saying my locale is und.

[d-loose]

its saying my locale is und.

That means the locale is 'undetermined', so either the flutter framework has problems parsing your locale, or there's already something broken in your system setup. In either case, we should handle this case properly.

Could you post the output of

locale

as well?

[mguinhos]

Sure,

$ locale
LANG=pt_BR.UTF-8
LANGUAGE=pt_BR:
LC_CTYPE="pt_BR.UTF-8"
LC_NUMERIC="pt_BR.UTF-8"
LC_TIME="pt_BR.UTF-8"
LC_COLLATE="pt_BR.UTF-8"
LC_MONETARY="pt_BR.UTF-8"
LC_MESSAGES="pt_BR.UTF-8"
LC_PAPER="pt_BR.UTF-8"

LC_ADDRESS="pt_BR.UTF-8"

[mguinhos]

@d-loose

[d-loose]

Seems like Flutter doesn't parse LANGUAGE=pt_BR: correctly. The resulting locale is 'und' in this case. Both pt_BR and pt_BR:pt work correctly though.

@robert-ancell I suppose this happens at the level of the engine - do you know more?

[robert-ancell]

We used g_get_language_names in the engine instead of writing our own parser with the hope this would do the right thing... However it seems to make both duplicate and empty locales; parsing LANGUAGE=pt_BR: returns "pt_BR", "pt", "", "C". I suspect the empty string is confusing Flutter and making the "und" locale.

[robert-ancell]

Sigh, and LANGUAGE="pt_BR: :" also returns " " and "".

[robert-ancell]

See https://github.com/flutter/engine/pull/55091, this should hopefully improve things.

[d-loose]

Great, thanks a lot for digging into this!

@d-loose do you've got an idea? Nevermind, I just saw that there are more issues ongoing ... I'll guess you're already on it.
