When changing the year, sometimes the month gets changed to a seemingly random month. Same with month/day.

To reproduce:

        DatePickerWidget(
            initialDate: DateTime.now(),
            firstDate: DateTime.now(),
            onChange: (value, _) {
              print(value.toString());
            }),

• select next month (Dec)
• select next year (2021) -> february gets selected

OR

• select next month (Dec)
• select first
• select current month (Nov) -> 9th gets selected

when using the DatePickerWidget and scrolling the day column to the value 1, onChange is not triggered and scrolling the month will revert the day value to the last day chosen before 1, deleting the lines 308-309 of the file date_picker_widget.dart solves the issue, but I don't know if it have side effects.

After Flutter 1.20 DiagnosticableMixin is officially deprecated. So i cannot use the library and i get this error

Error: Type 'DiagnosticableMixin' not found. class DateTimePickerTheme with DiagnosticableMixin { ^^^^^^^^^^^^^^

I believe you just need to remove "with DiagnosticableMixin" that will fix the issue

Thanks in Advance

code:

await DatePicker.showSimpleDatePicker(
    context,
    initialDate: DateTime.now(),
    dateFormat: "dd-MMMM-yyyy",
    locale: DateTimePickerLocale.th,
  );

This bug was introduced with the newest version (0.3.0). On 0.2.3. it works as expected.

To reproduce:

DatePickerWidget(
              initialDate: DateTime.now(),
              firstDate: DateTime.now(),
              onChange: (value, _) {
                print(value.toString());
              }),

• select 2021-Jan-01
• -> onChange value prints 2021-01-02

This is a very critical bug so I downgraded to 0.2.3., which introduces the old jumping date bug

Would be highly appreciated if this could be fixed, so i can enjoy the previous bugfix 😊

On latest beta 1.17.0

Removed default CupertinoPicker selection overlay introduced in Flutter 2 to adhere to the original design of holo date picker. Fixes #32.

Note: the selectionOverlay property docs say to remove it one can set it to null, but there seems to be a bug in the Flutter framework itself that doesn't allow it when using null safety, so until a fix is rolled out for that issue, we're just going to have to settle for overwriting that property with an empty Container().

Hi, I love the flutter_holo_date_picker and use it for multiple projects.

However, while trying to display date format of : "MM-dd(E)", widget crashes showing

RangeError (index): Invalid value: Not in inclusive range 0..6: 7

I was using DatePickerWidget with locale unset(to default).

Here's my full code for the widget

DatePickerWidget(
   looping: false, 
   firstDate: DateTime(2020, 1, 1),
   lastDate: DateTime.now(),
   initialDate: DateTime.now(),
   dateFormat: "MM-dd(E)",
   onChange: (DateTime newDate, _) =>_selectedDate = newDate,
   pickerTheme: DateTimePickerTheme(
      itemTextStyle:TextStyle(color: Colors.white, fontSize: 19),
      showTitle: false,
   ),
),

Thanks for everything!

I have found an issue first step check current date is 18 August 2022. It shows that "2022-08-18" is correct. and the second step I selected was 18 August 2023. It shows that "2023-05-18" is not correct. @kfiross

When handling dates in Flutter, I'm used to using the buildt-in Localizations.localeOf(context).languageCode to get the correct format on dates and so on. An example of formatting dates: DateFormat.yMMMMd(Localizations.localeOf(context).languageCode).format(value). The date is then formatted to to match the language of the device. I'd like to be able to do the same with this package, but it doesn't accept a language code string. Instead I'd have to do something like this;

DateTimePickerLocale dateTimePickerLocale;

switch (locale.languageCode) {
  case 'nb':
    dateTimePickerLocale = DateTimePickerLocale.no_nb;
    break;
  case ...

  default:
    dateTimePickerLocale = DateTimePickerLocale.en_us;
    break;
}

This is not a great solution, since it would have to be updated every time a language is added. It would be a much more flexible solution to let the showSimpleDatePicker method accept a language code string instead.

It appears that french support was implemented in l18n folder but not linked in localeFromString method.

Before :

print(DatePicker.localeFromString('fr')); // DateTimePickerLocale.en_us

After :

print(DatePicker.localeFromString('fr')); // DateTimePickerLocale.fr

What does this PR do?

Implement dividerHeight and dividerThickness to change the size of dividers.

Usage

DatePicker.showSimpleDatePicker(
  context,
  initialDate: DateTime(1994),
  firstDate: DateTime(1960),
  dateFormat: "dd-MMMM-yyyy",
  dividerHeight: 1.0,
  dividerThickness: 1.0,
);

I've found that, after setting the attribute pickerHeight in the DateTimePickerThemeand then setting it to the DatePickerWidget's pickerTheme, the numbers (day/month/year) are not vertically aligned.

Screenshot:

Code:

...
DateTimePickerTheme myTheme = const DateTimePickerTheme(
      pickerHeight: 200
);
...
DatePickerWidget(
    initialDate: DateTime.now(),
    lastDate: DateTime.now(),
    dateFormat: "dd-MM-yyyy",
    pickerTheme: myTheme,
)

If you slide between the items, the element gets repositioned in the middle as well:

My year is an additional 543 years from the year by A.D. I already set the locale property to my country(TH). I see the dateFormat property config this but can't add 543 years.

I can set the initialDate property by DateTime(DateTime.now().year + 543) but it is not correct. February have 28 days and 29 days every 4 years. For the example: A.D. 2020 => 29 days in TH we add 543: 2563 => 29 days if I use DateTime(DateTime.now().year + 543), it will wrong: A.D. 2020 => 29 days TH 2563 => 28 days //2564 => 29 days

My project saves date time with A.D. and shows with year + 543. How to add years or shows the custom year?

I need it.
