How to change FLUTTER DropdownMenuItem's textDirection (change widget direction) - flutter

Question

I need to change widget's textDirection according to the language selection. I have a variable for textDirection in my global translation class and add it to parent widgets. All are work fine except DropdownMenuItems. I tried with wrapping text widget by Directionality widget but still not working as expect.
Ex: when I change language which use rtl items should align to right which
is not happening currently.
return DropdownMenuItem(
child: Directionality(textDirection: Translations.textDirection ,
child: new Text(listItems,textDirection: Translations.textDirection,)
...
Also I tried adding textDirection after wrapped whole DropdownButton with a Container.
return Container(
child: Row(
mainAxisAlignment: MainAxisAlignment.end,
textDirection: Translations.textDirection,
children: <Widget>[
DropdownButton(
But still not work. What should I do to change the textDirection of DropdownMenuItems ?? Any help would be appreciate.
note: I can't add textDirection to MaterialApp. Need to change it when select different languages.

Answer 1

I Solved it
DropdownButton<String>(
hint: Text(
'City',
style: TextStyle(fontFamily: 'Cairo'),
),
isExpanded: true,
value: dropdownValue,
elevation: 4,
style: TextStyle(
color: Colors.deepPurple, fontFamily: 'Cairo'),
underline: Container(
height: 2,
color: Colors.deepPurpleAccent,
),
onChanged: (String newValue) {
setState(() {
dropdownValue = newValue;
debugPrint(cityInfo.indexOf(newValue).toString());
});
},
items:
cityInfo.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(
value: value,
child: Container(
alignment: Alignment.centerRight,
child: Text(
value,
),
),
);
}).toList(),
),

Answer 2

For left to right text direction:
Text('MyText', textDirection: TextDirection.ltr,)
OR
For right to left text direction:
Text('MyText', textDirection: TextDirection.rtl)

Answer 3

DropdownButton<String>(
items: <String>['A', 'B', 'C', 'D'].map((String value) {
return new DropdownMenuItem<String>(
value: value,
child: new Center(
child: Text(value),
),
);
}).toList(),
onChanged: (_) {},
),
Just wrap the DropDownMenuItem child Widget(Text) with a Center widget
Update: Sorry I miss understood it as how to center the widget.
You can add TextDirection.rtl or TextDirection.ltr to textDirection property
If it does not work try wrapping it a Row with mainAxisAlignment to end
