Using Localization inside a list - Flutter - flutter

Question

My application contains localizations (translation "en","ar"), in my translation JSON files there are cities that users will choose while registration process these cities appears in a DropDownButtonFormField widget as follows:
final provincesField = DropdownButtonFormField<String>(
value: dropDownValue,
onChanged: (String? newValue) {
setState(() {
dropDownValue = newValue!;
});
},
items: provinces.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(
value: value,
child: SizedBox(
width: 100.0,
child: Text(value, textAlign: TextAlign.center),
));
}).toList(),
elevation: 4,
decoration: InputDecoration(
prefixIcon: Icon(Icons.flag_circle),
labelText: AppLocalizations.of(context)!.chooseProvinence,
alignLabelWithHint: true,
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(10),
),
),
);
the cities are declared in this list:
List<String> provinces = [
'عمان',
'إربد',
'الزرقاء',
'المفرق',
'الطفيلة',
'عجلون',
'معان',
'الكرك',
'مادبا',
'العقبة',
'البلقاء',
'جرش'
];
String dropDownValue = 'عمان';
what am trying to achieve is that cities will appear to user based on the app language. I have tried to use AppLocalizations.of(context)!.city inside of the list but its not working so i believe there is some way to declare the list values based on localization, ill appreciate any help

Answer 1

Suppose below localizations data is your cities list
English:
"Dhaka" : "Dhaka",
"Chittagong" : "Chittagong",
"Cumilla" : "Cumilla",
"Rajshahi" : "Rajshahi",
"Bhola" : "Bhola",
Arabic:
"Dhaka" : "دكا",
"Chittagong" : "شيتاغونغ",
"Cumilla" : "كوميلا",
"Rajshahi" : "راجشاهي",
"Bhola" : "بولا",
initialize your the localization keys of your cities and dropDownValue
List<String> provinces = [
"Dhaka",
"Chittagong",
"Cumilla",
"Rajshahi",
"Bhola",
];
String dropDownValue = 'Dhaka';
here is the widget. I used getx localization. So I used 'tr' after the child text of DropdownMenuItem. I hope it's can help u.
Widget TestWidget() {
return DropdownButtonFormField<String>(
value: dropDownValue,
onChanged: (String? newValue) {
// To print the value with localization
print(newValue!.tr);
},
items: provinces.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(value: value, child: Text(value.tr));
}).toList(),
elevation: 4,
decoration: InputDecoration(
prefixIcon: Icon(Icons.flag_circle),
labelText: 'Select',
alignLabelWithHint: true,
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(10),
),
),
);
}
If you need to store the city in database or anywhere with localization then you can use it like [dropDownValue.tr]
