There are four presentations for DateTimePicker and can be defined in the type parameter:
DateTimePickerType.date will present a text field with the action tap showing a datePicker dialog box;DateTimePickerType.time will present a text field with the action tap showing a timePicker dialog box;DateTimePickerType.dateTime will present a text field with the action tap showing a datePicker dialog box then a timePicker dialog box;DateTimePickerType.dateTimeSeparated will display two text fields side by side, the first for date and the second for time. Each displaying their respective dialog box, datePicker and timePicker in the tap action;DateTimePicker(
type: date, // options: [date | time | dateTime | dateTimeSeparated], default is date
...
)
initialValue or controller.text can be null, empty or a DateTime string otherwise it will throw an error.
DateTimePicker(
initialValue: '',
firstDate: DateTime(2000),
lastDate: DateTime(2100),
dateLabelText: 'Date',
onChanged: (val) => print(val),
validator: (val) {
print(val);
return null;
},
onSaved: (val) => print(val),
);
More complete example:
DateTimePicker(
type: DateTimePickerType.dateTimeSeparate,
dateMask: 'd MMM, yyyy',
initialValue: DateTime.now().toString(),
firstDate: DateTime(2000),
lastDate: DateTime(2100),
icon: Icon(Icons.event),
dateLabelText: 'Date',
timeLabelText: "Hour",
selectableDayPredicate: (date) {
// Disable weekend days to select from the calendar
if (date.weekday == 6 || date.weekday == 7) {
return false;
}
return true;
},
onChanged: (val) => print(val),
validator: (val) {
print(val);
return null;
},
onSaved: (val) => print(val),
);
