The current iOS system locale always seems to be en_US about i18n_extension

[marcglasberg]

Maybe it has something to do with this issue: flutter/flutter#14128

What do you think?

It seems that one needs to add an es localization in Xcode, per flutter/flutter#14128. However, the way I18n picks up its locale, it obtains the correct local after its child widgets have been built and it doesn't bother rebuilding them.

Hey, i facing with same issue, but i can resolve my problem changing the development language, in project.pbxproj have the:
DevelopmentRegios = en; // Change this to your language (or the language you want) (example: French = fr, Portuguese = pt...)

and have the knownRegions too, you need change, my knowRegions is default =
knownRegions = (
en,
Base,
),
and i added in first my language, and its works to mee, if not working, we'll try find your problem

[lucas-sesti]

Yes... but i can't resolve just seeing this issue... i found in a post of stackoverflow (i don't have the link anymore, but i'll try again)

[marcglasberg]

@lucas-sesti Ok!

@maguro Does that solve your problem?

[suesitran]

I tried solution from flutter/flutter#14128, it works in debug but failed in release build. Any other clue?

[lucas-sesti]

@suesitran Did you try what i said? Because i tested in debug and release build, and both works

[suesitran]

Yes I tried it, does not work. My development region is English (not sure if i have to change to en), and known region is (en, Base)

[lucas-sesti]

Probably you don't need change to en.. but, if you want change to other languages, you need put in first options off knownRegions and in development region

I can vouch for the solution.

The following code wasn't working properly:

localeListResolutionCallback: (locales, supported) {
  Locale locale = Locale('en', 'US');

  for (var loc in locales) {
    if (supported.contains(loc)) {
      locale = loc;
      break;
    }
  }

  return locale;
}

Even though the Device's Locale was set to a different language the locales parameter was returning: [en_US, pt_BR, en]. Not honoring the priority set on the device.

The solution:

• Add the supported languages on the XCode project (picture 1).
• Add Localized resources can be mixed to YES on the Info.plist (picture 2).

References:

(Picture 2)

After those settings set, the locales param is rightfully being returned as [pt_US, pt_BR, en]
(pt_US in this case is expected to be first because the phone region is set to the USA)

Any updates on it?
