How to completely suppress "There are no translations in 'en_us' for 'someString'"? about i18n_extension

[marcglasberg]

You can disable recording this, by doing:

Translations.recordMissingKeys = false;
Translations.recordMissingTranslations = false;

You can also set up callbacks that the i18n_extension package will call whenever it detects a missing translation. You can then choose when to log or not, by creating your own logic. To do that, simply inject your callbacks into Translations.missingKeyCallback and Translations.missingTranslationCallback. For example:

Translations.missingTranslationCallback = (key, locale) => doSomething();

Yes, I'll make it case insensitive. Thanks!

[marcglasberg]

Yes, I believe these messages should not be displayed. I should fix this.

I think these messages is useful when you provided en_US only but the selected locale is en_UK.

To suppress these errors you may limit the locale to Locale('en') and Locale('de') only.

But it also makes sense if @marcglasberg can add an option to hide these errors when the language matched.

I bump into this problem too,but I'm using code zh_TW and en_US. It just keep complaining about missing translation in en_us and zh_tw even through it actually works fine. It seems there is some problem for internal logic to match the standards code.

I'm trying to switch to lowercase code but when I pass invalid local to supportedLocales now it will report error and focus me to use the standard code mentioned in #14.

      supportedLocales: const [

        Locale('zh', "tw"),
      ],

Thanks but I still need the missing translation report to find out if I have missing any translation. Later I found out I need to use whole lowercase code in my translation to stop the warning. It's kind of confusing people because config and translation code
required format isn't match.
I suggest to compare code case insensitive in internal check flow to avoid this kind of problem. :D
