Future<DateTime?> onCalendarWidgetTap(BuildContext context) async {
final RenderBox? renderBox = context.findRenderObject() as RenderBox?;
final nowDate = DateTime.now();

return showCupertinoCalendarPicker(
context,
widgetRenderBox: renderBox,
minimumDateTime: nowDate.subtract(const Duration(days: 15)),
initialDateTime: nowDate,
maximumDateTime: nowDate.add(const Duration(days: 360)),
mode: CupertinoCalendarMode.dateTime,
timeLabel: 'Ends',
onDateTimeChanged: (dateTime) {},
);
}

showCupertinoTimePicker function. #
The showCupertinoTimePicker function shows a time picker around your widget.
Usage Example
Future<TimeOfDay?> onTimeWidgetTap(BuildContext context) async {
final RenderBox? renderBox = context.findRenderObject() as RenderBox?;

return showCupertinoTimePicker(
context,
widgetRenderBox: renderBox,
onTimeChanged: (time) {},
);
}

Functions Usage Example #
Call the showCupertinoCalendarPicker passing date constrains and widget's RenderBox of the widget above/below which you wish to display the calendar.
@override
Widget build(BuildContext context) {
return CupertinoApp(
localizationsDelegates: const [
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
home: CupertinoPageScaffold(
child: Builder(
builder: (context) {
/// Passing exactly this `BuildContext` is mandatory here to
/// get the `RenderBox` of the appropriate widget.
return YourWidget(
onTap: () => onTap(context),
);
},
),
),
);
}

/// The `BuildContext` comes from the `Builder` above the widget tree.
Future<void> onTap(BuildContext context) {
final renderBox = context.findRenderObject() as RenderBox?;
final nowDate = DateTime.now();

return showCupertinoCalendarPicker(
context,
widgetRenderBox: renderBox,
minimumDate: nowDate.subtract(const Duration(days: 15)),
initialDate: nowDate,
maximumDate: nowDate.add(const Duration(days: 360)),
);

How to get a RenderBox? #
There are 3 simple ways of how you can get the widget's render box to pass it to the showCupertinoCalendarPicker or showCupertinoTimePicker function.
You can choose any of these.

Wrap your widget with Builder widget.

Builder(
builder: (context) {
return YourWidget(
onTap: () => onTap(context),
);
},
);

Future<void> onTap(BuildContext context) {
/// And here you can get the `RenderBox` of your widget
/// using the `Builder`s `BuildContext`
final renderBox = context.findRenderObject() as RenderBox?;
return showCupertinoCalendarPicker(...);
}

copied to clipboard

Use a GlobalKey.

final globalKey = GlobalKey();

@override
Widget build(BuildContext context) {
return CupertinoApp(
localizationsDelegates: const [
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
home: CupertinoPageScaffold(
child: YourWidget(
key: globalKey,
onTap: onTap,
),
),
);
}

Future<void> onTap(BuildContext context) {
/// And here you can get the `RenderBox` of your widget using the `GlobalKey`.
final renderBox = globalKey.currentContext?.findRenderObject() as RenderBox?;
return showCupertinoCalendarPicker(...);
}

Pass a BuildContext directly from your widget's build method.

class YourWidget extends StatelessWidget {
const YourWidget({
required this.onTap,
});

final void Function(BuildContext context) onTap;

@override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () => onTap(context),
child: ...,
);
}
}

Future<void> onTap(BuildContext context) {
/// And here you can get the `RenderBox` of your widget's `build` method.
final renderBox = context.findRenderObject() as RenderBox?;
return showCupertinoCalendarPicker(...);
}
