Unconsistent _osLocale #141

HugoHeneault · 2020-04-13T13:12:10Z

This bug isn't easy reproducible in debug, only in release mode and I don't know how to fix it.

Edit: We found a way to reproduce it, here and there is an open issue on flutter repo.
There also is a workaround providen by @Overman775

On first launch, it starts in french (fr_FR) on a french iPhone (SE or 6).
On second launch, it starts in english (en_US)

Then it randomly starts in french or english depending on some unknown dark magic...

I added required keys in Info.plist:

<key>CFBundleLocalizations</key>
<array>
	<string>fr</string>
	<string>en</string>
	<string>ca</string>
	<string>de</string>
	<string>es</string>
	<string>eu</string>
	<string>it</string>
	<string>nl</string>
	<string>zh</string>
</array>

And also

<key>CFBundleDevelopmentRegion</key>
<string>fr</string>

<key>CFBundleAllowMixedLocalizations</key>
<true/>

I ran flutter clean.

When I run flutter run ios it works nicely but when I deploy it to testflight it doesn't.

Here are the logs I gathered with the console:

1st launch:

14:49:44.220356+0200	Runner	flutter: EasyLocalization
14:49:44.221033+0200	Runner	flutter: initState
14:49:44.224536+0200	Runner	flutter: easy localization: Build
14:49:44.224589+0200	Runner	flutter: easy localization: Device locale fr_FR
14:49:44.224626+0200	Runner	flutter: _osLocale fr_FR
14:49:44.224682+0200	Runner	flutter: _checkInitLocale locale: fr _osLocale: fr
14:49:44.224719+0200	Runner	flutter: localePath assets/langs/st/fr.json

2nd launch:

14:50:04.279576+0200	Runner	flutter: EasyLocalization
14:50:04.290749+0200	Runner	flutter: initState
14:50:04.291415+0200	Runner	flutter: easy localization: Build
14:50:04.293339+0200	Runner	flutter: easy localization: Device locale en_US
14:50:04.293450+0200	Runner	flutter: _osLocale en_US
14:50:04.293597+0200	Runner	flutter: _checkInitLocale locale: fr _osLocale: en
14:50:04.293724+0200	Runner	flutter: _checkInitLocale locale: en _osLocale: en
14:50:04.293760+0200	Runner	flutter: localePath assets/langs/st/en.json

Here is my setup:

final String assetsLocalePath = 'assets/langs/st/';
final List<String> supportedLocales = [
  'fr',
  'en',
  'ca',
  'de',
  'es',
  'eu',
  'it',
  'nl',
  'zh',
];

runApp(EasyLocalization(
      path: assetsLocalePath,
      useOnlyLangCode: true,
      child: MyApp(),
      saveLocale: false,
      supportedLocales:
          supportedLocales.map((locale) => Locale(locale)).toList(),
    ));

What shall I do?
Thanks a lot!

@HugoHeneault plz check #130
#130 (comment)

HugoHeneault · 2020-04-13T17:16:10Z

@aissat I already did it 🤔

HugoHeneault · 2020-04-13T17:53:15Z

@aissat I just figured out that on the comments you gave me every locale has some files localized. What files should it be? 🤔

aissat · 2020-04-13T17:55:22Z

@Overman775 plz check this

Overman775 · 2020-04-14T00:00:59Z

@HugoHeneault version 2.1.0+1?

HugoHeneault · 2020-04-14T08:25:17Z

I was on 2.1.0+0, I can try with 2.1.0+2 if you think it might change (but I can't see what changed though)

Thanks for your help! 👍

Overman775 · 2020-04-14T08:50:11Z

@HugoHeneault yep, try latest 2.1.0+2

HugoHeneault · 2020-04-14T09:12:16Z

I'm on it! Will come back to you later.

The AssetLoader api changed so I need to update my custom asset loader. Might be worth it to update more than the the +0 to +2 for next times, so we know changes are required :)

HugoHeneault · 2020-04-14T14:12:24Z

So I tried multiple builds:

I updated to latest 2.1.0+2: fr on 1st load the english on 2nd one
I re-created all the localizations with the screenboards/main files localizations: fr on 1st load the english on 2nd one
I removed locale: EasyLocalization.of(context).locale, from my MaterialApp: fr on 1st load the english on 2nd one

I'm running out of idea. Do you want me to provide you the builds so you can check it?

Overman775 · 2020-04-14T19:42:37Z

@HugoHeneault I don’t know what the problem is, maybe device bug

Try run example on your iPhone, don't forgeret add lang in xcode and json

HugoHeneault · 2020-04-20T13:09:24Z

Tried on 2 different devices. Same behavior.

The main problem is we only have this issue on release versions (coming from testflight).
I am on Flutter beta (Flutter 1.17.0). Maybe the issue is here?

HugoHeneault · 2020-04-20T16:05:07Z

Looking on my project.pbxproj file, there is only "en" in knownRegions. Would it has something to do?

HugoHeneault · 2020-04-21T09:15:22Z

@Overman775 I tested the example app on my iPhone, I reproduce the error! Would you help me? :)

Why is there no CFBundleLocalizations prop in Info.plist? Isn't this one of the step described in #130 (comment)?

Here are the logs from my device:

I ran it in debug mode from AndroidStudio.

HugoHeneault · 2020-04-21T09:16:09Z

I pushed my source code (with Info.plist) on https://github.com/OwnWeb/easy_localization/tree/issue/unconsistent-locale

Overman775 · 2020-04-22T15:39:29Z

@HugoHeneault bug confirm.

@aissat reproduce: clean instal/debug on iOS emulator --> close(don't change lang) --> get off from memory iOS --> run again. Tested on stable & beta flutter channels. Android witout bug.

HugoHeneault · 2020-04-24T09:48:01Z

@Overman775 Cool. My setup is OK then. Hope you'll find the issue as I've been looking on it for quite awhile and have no idea on what's wrong.

@aissat If I can be of any help don't mind asking me!

Thanks a lot

Overman775 · 2020-04-24T19:28:52Z

@aissat @HugoHeneault find, problem in io.Platform.localeName... i thin its Flutter/Dart bug

hack:

Future<Locale> _getDeviceLocale() async {
    while(Platform.localeName == null){
      await Future.delayed(const Duration(microseconds: 300), (){});
    } 
    final _deviceLocale = await findSystemLocale();
    log('easy localization: Device locale $_deviceLocale');
    return _localeFromString(_deviceLocale);
  }

HugoHeneault · 2020-04-27T14:58:37Z

@Overman775 Awesome! I'm gonna try your workaround! Is it ok if I add it before my runApp call?

On your flutter bug repo there is no CFBundleLocalizations key in the Info.plist? Is it on purpose?

Thanks!

Overman775 · 2020-04-27T15:00:18Z

@Overman775 Awesome! I'm gonna try your workaround! Is it ok if I add it before my runApp call?

Yep

HugoHeneault · 2020-04-27T16:30:41Z

@Overman775 Your workaround seems to work! 🎉

Thanks a lot for your time and your help!
I'm deploying to testflight 🤞

HugoHeneault · 2020-04-28T10:09:38Z

As it's really the end of a long and tiring debugging we're thinking of a (small) recurring support of your project to thank you for your nice work! 🍻

How doest it work as you're at least 2 collaborators working on it? :)

Overman775 · 2020-04-28T13:11:44Z

@HugoHeneault Glad that helped you 😃. Let's hope the Flutter/Dart team fixes it in Flutter

fork repository
work with develop branch
pull reqwest to this repository develop branch
work with code review
we merge master branch

HugoHeneault · 2020-04-28T15:27:43Z

@Overman775 I was thinking about financial support, as we don't have much time to invest in working on this repo. :)

Overman775 · 2020-04-28T15:36:17Z

@HugoHeneault Thanks 😃

Overman775 · 2020-09-03T09:01:57Z
