@aleksanderwozniak, Russian locale haven't work. I've done all by instruction. I found samples of code for Portuguese and implemented it and It works. But when I try to use Russian or Ukrainian or Belorussia it wont. I've even try Iraq and its work) but not with 'ru_RU'

Can you check if locale: 'ru_RU' works for you in example project? It doesn't seem to have any issues on my end:

It seems like it won't work with intl localisation... initializeDateFormatting conflicting with

[
const AppLocalizationDelegate(),
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
];

I just tried it on the example project - looks like you can safely remove the conflicting initializeDateFormatting() if you are using localizationsDelegates. Doing so still allowed me to use locale: 'ru_RU' without any hiccups.

The problem is not solved with deleting initializeDateFormatting() in main function. The problem remains if there is a need to use some functions from intl package with table_calendar widget. I've also tried polish and spanish locale and they work fine but russian locale doesn't work.

@Artem-Sobolev
Please try running the example project with 'ru_RU' locale and see if the problem is still present.

For header locale works perfectly in Russian, but not for weekdays. It's strange...

@KrillioSokolov So, it seems I have found the root of the problem for myself. The problem was in calling

dowTextBuilder: (date, locale) {
          return DateFormat.E(locale)
              .format(date)
              //.substring(0, 3)
              .toLowerCase();
        }

so the issue isn't actually in this package or something but in my code. Here as you can see I'm trying to cut the string and only take first three letters. And here is the trick: in english you have for example "mon, tue, wed and etc", but in russian you get "пн, вт, ср, чт..." thus you can't take the third letter when taking a substring. It was a bit confusing to find since debug console messages didn't point on this line but after few shenanigans I've finally found it. After I've found this line I went through all similar lines of code and fixed them where it is needed and now everything works fine.

Have same issue in my project. Tried to use ru_RU in example code. It doesn't work.

Looks like we copy code from the medium, where table calendars was compared)) because I've the same lines of code))

@Tamerlanchiques
What does the debug console log say? Also, what's your Flutter and package version?

[Tamerlanchiques]

@aleksanderwozniak Just ran table_calendar/example and ru_RU locale works fine for me so never mind.

[Tamerlanchiques]

But, 2 weeks / week / month selector didn't translated.

[aleksanderwozniak]

Looks like this can be closed now.

@Tamerlanchiques
You need to provide your own translations for the format button: https://github.com/aleksanderwozniak/table_calendar#specifying-a-language. Use availableCalendarFormats for that.
