CupertinoNavigationBar's "Close", "Back", and "Cancel" buttons are not localized.

"Close" button

Originally reported here: https://stackoverflow.com/questions/59487887/flutter-cupertino-app-close-button-not-translated

Reproduced Below:

I am writing an iOS App with Cupertino Style in flutter.

The app should be available in English and German. I am using the following translation delegates in the CupertinoApp:
  RefreshLocalizations.delegate,
  GlobalCupertinoLocalizations.delegate,
  GlobalWidgetsLocalizations.delegate,
  GlobalMaterialLocalizations.delegate,
Unfortunately, the "Close" button in the CupertinoNavigationBar is not not translated.

Why? And how can I change this?

"Back" button

flutter/packages/flutter/lib/src/cupertino/nav_bar.dart

Lines 2032 to 2034 in 449079d

    
           if (previousTitle.length > 12) { 
        
             textWidget = const Text('Back'); 
        
           }

"Cancel" button

Introduced by #159120

Hi @LongCatIsLooong
Is this issue still valid?
Thank you

I believe so.

Still valid today:

flutter/packages/flutter/lib/src/cupertino/nav_bar.dart

Lines 1092 to 1096 in 1fef591

    
           leadingContent = CupertinoButton( 
        
             child: const Text('Close'), 
        
             padding: EdgeInsets.zero, 
        
             onPressed: () { route.navigator.maybePop(); }, 
        
           );

Any progress on this issue? Problem still exists.

I can confirm this is still a problem. Created a new project in stable and added a simple CupertinoApp with a CupertinoPageScaffold with a CupertinoNavigationBar, the open it using the Navigator.push and CupertinoPageRoute with fullScreenDialog set to true. The app was localized as per this to support Norwegian (nb). I added a CupertinoDatePicker just to confirm that it was correctly localized.

Still a problem as of 3.19.6 :(
