Answer 1

I had this problem, tried the package flutter_cupertino_date_picker but it looks like it don't have the hability to format only month and year excluding day, so you need to program on it to extend the capabilities. To me seemed more logical to change the build in CupertinoDatePicker that comes with Flutter, what I did was copy all the content of '/Users/your_user_name/developer/flutter/packages/flutter/lib/src/cupertino/date_picker.dart' in another file in my local envirronment, I called cupertino_picker_extended.dart, then (because I wanted a quick way) on line 1182 I changed: Text(localizations.datePickerDayOfMonth(day),... for Text('',...
Then where you need to use the customed Picker call it like:
import 'package:local_app/ui/widgets/cupertino_picker_extended.dart' as CupertinoExtended;
and use it:
CupertinoExtended.CupertinoDatePicker(
onDateTimeChanged: (DateTime value) {
setDate('${value.month}/${value.year}', setDateFunction,
section, arrayPos);
},
initialDateTime: DateTime.now(),
mode: CupertinoExtended.CupertinoDatePickerMode.date,
),
This is the result:
Hope it help someone and save the time I been looking for a easy and quick solution for my problem.

}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key}) : super(key: key);
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
String _datetime = '';
int _year = 2018;
int _month = 11;
String _lang = 'en';
String _format = 'yyyy-mm';
bool _showTitleActions = true;
TextEditingController _langCtrl = TextEditingController();
TextEditingController _formatCtrl = TextEditingController();
#override
void initState() {
super.initState();
_langCtrl.text = 'zh';
_formatCtrl.text = 'yyyy-mm';
DateTime now = DateTime.now();
_year = now.year;
_month = now.month;
}
/// Display date picker.
void _showDatePicker() {
final bool showTitleActions = false;
DatePicker.showDatePicker(
context,
showTitleActions: _showTitleActions,

if (!showTitleActions) {
_changeDatetime(year, month);
}
},
onConfirm: (year, month,date) {
_changeDatetime(year, month);
},
);
}
void _changeDatetime(int year, int month) {
setState(() {
_year = year;
_month = month;
_datetime = '$year-$month';
});
}

Answer 3

There has been updates on the flutter_cupertino_date_picker package. You can now specify a date format
DatePicker.showDatePicker(context,
maxDateTime: DateTime.now(),
dateFormat:'MMMM-yyyy'
);

Answer 4

This is the way to go
Widget datetime() {
return CupertinoDatePicker(
initialDateTime: DateTime.now(),
onDateTimeChanged: (DateTime newdate) {
print(newdate);
},
minimumYear: 2010,
maximumYear: 2030,
mode: CupertinoDatePickerMode.date,
);
}
