How format Date time using DateTimePicker and get the selected date as String?-CodePudding

I tried using this=> choosenFromCalender = DateFormat('dd-MM-yyyy').format(newValue);

but the for this error not able to format properly.

  DateTimePicker(
                           
                            dateMask: 'dd-MM-yyyy',
                            initialValue: DateTime.now().toString(),
                            type: DateTimePickerType.date,
                            firstDate: DateTime(1800),
                            lastDate: DateTime(2050),                                
                            onChanged: (newValue) {
                              print(newValue);  // for now its `2022-07-27` i want `27-07-2022`
                            
                            },

                            onSaved: (value) {

                            },
                          ),

CodePudding user response：

The Issue is that you get from the newValue a string back, but DateFormat can only handle DateTime formats. What you can do is, that you parse your String to a DateTime object.

DateTime dt = DateTime.parse(newValue);

The dt object you can use then to Format your DateTime.

But there is an better alternative. You can do both operations together.

 print(DateFormat('dd-MM-YYYY').parse(newValue));

Prints you the Formatted Date as you want with the value from the onChanged Method

CodePudding user response：

You need to formate picked date

for that you need to put below code in onChanged method

newValue=DateFormat('dd-MM-yyyy').format(DateTime.parse(newValue);
