Hi,God！

As shown in the figure, I want the language (Chinese) used by the printer service in the iOS app.
I tried to add localization below, but it didn't work

@override Widget build(BuildContext context) { return MaterialApp( localizationsDelegates: const [ GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate, GlobalCupertinoLocalizations.delegate, ], supportedLocales: const [ Locale('zh', 'CN'), ], locale: const Locale('zh', 'CN'), /// code ); }
