ios – Placeholders for capabilities (like placeholders for vars in Strings)

I’m new in flutter and programming, so do not e too harsh please. My downside is following:
I wish to create a customized button for my menu entries and as an alternative of classical textual content parameter, I wish to parse an arb-key (or fairly getter), so the AppLocalizations appears to be like up for the important thing and returns corresponding getter in right language.

import 'bundle:flutter/materials.dart';
import 'bundle:getwidget/getwidget.dart';
import 'bundle:flutter_gen/gen_l10n/app_localizations.dart';



class ExtendableMenuNavigationEntry extends StatelessWidget {
  last Widget baby;
  last Perform() callback;
  last Perform() arbGetter;

  const ExtendableMenuNavigationEntry({
    tremendous.key,
    required this.baby,
    required this.callback,
    required this.arbKey,
  });

  
  @override
  Widget construct(BuildContext context) {
    return GFButton(
      onPressed: () => callback,
      textual content:  AppLocalizations.of(context)!.arbGetter,
      form: GFButtonShape.tablets,
      fullWidthButton: true,
    );
  }
}

Nonetheless, I obtain an error:

The getter 'arbGetter' is not outlined for the kind 'AppLocalizations'.
Attempt importing the library that defines 'arbGetter', correcting the identify to the identify of an current getter, or defining a getter or discipline named 'arbKey'

AppLocalisation is autogenerated, I adopted this information: https://docs.flutter.dev/ui/accessibility-and-internationalization/internationalization

Due to my inexperience, I’m not even certain how I ought to name my downside. I do know you should utilize placeholders for vars in Strings, however I do not know tips on how to do it for Features…
