How to get the month and year of month view in Flutter Calendar?
In the Flutter Calender, you can retrieve the month and year of month view by using onViewChanged callback of calendar.
Using the onViewChanged callback, you can access the month and year of the month view through the visibleDates property of the ViewChangedDetails argument.
void viewChanged(ViewChangedDetails viewChangedDetails) {
SchedulerBinding.instance!
.addPostFrameCallback((Duration duration) {
setState(() {
_month = DateFormat('MMMM').format(viewChangedDetails
.visibleDates[viewChangedDetails.visibleDates.length ~/ 2]).toString();
_year = DateFormat('yyyy').format(viewChangedDetails
.visibleDates[viewChangedDetails.visibleDates.length ~/ 2]).toString();
});
});
}
Assign _month and _year values to the Text widgets to display the values.
child: Column(
children: [
Container(
child: Text('Month: ' '$_month'),
),
Container(
child: Text('Year: ' '$_year'),
),
Expanded(
child: SfCalendar(
view: CalendarView.month,
dataSource: getCalendarDataSource(),
onViewChanged: viewChanged,
),
),
],
),

Hi Valentin,
Based on the shared information, we have checked and your requirement is “Show the month name in AppBar and localize the month name in Flutter Calendar”. By using the onViewChanged callback you can get the current visible month and format to the required locale. We have prepared the simple sample for the same. Please find the sample from the following link.

This works really well! However it doesn't show the title (month) on the set language (in this case german)
(I am using this method to place the month on the appBar)
class MyAppState extends State<Saveta> { String? _month, _year;
@override Widget build(BuildContext context) { return MaterialApp( localizationsDelegates: const [ //Sprachen GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate, GlobalCupertinoLocalizations.delegate, ], supportedLocales: const [ Locale('de'), ], locale: const Locale('de'), debugShowCheckedModeBanner: false,
