hi thanks for the package, after searching a lot a date time picker and date range picker I found that you package is the best, I have a request if you can add an option to edit the date time in a form field like the native date picker they have both options it'll be amazing, because for desktop some prefer to select the date with the keyboard, thanx

Hi, thanks a lot for your package, and happy holidays!

I find that the OmniDateTimePicker won't consider the Time information in my initial DateTime object. Here's an example:

DateTime date = DateTime.now().toUtc().add(const Duration(hours: -11))

final DateTime? dateTime = await showOmniDateTimePicker(
  context: context,
  is24HourMode: false,
  isShowSeconds: false,
  startInitialDate: date,
  startFirstDate: DateTime.now().toUtc().subtract(const Duration(days: 365)),
  startLastDate: DateTime.now().toUtc(),
  borderRadius: const Radius.circular(16),
);

This resulting picker will show the time as the current device time, instead of the date object's time which is 11 hours behind now.

Also, the FirstDate and LastDate time is not respected as a cutoff time for the time spinners. Also, opening the dialog and then tapping OK without changing anything will cause the resulting DateTime to be equal to the current day and time, regardless of the initial date passed. I can produce this on Android.

Function: DateTime? dateTime =await showOmniDateTimePicker(context: context);

I had put this function but the problem is when i pick date and time it doesn't save on the textfield. How can i solve this?

Thank you for this well designed and lightweight library.

In this PR, I propose we use localized default strings for the labels instead of hardcoded string values.

The MaterialLocalizations class is also used in the official calendar_date_picker. The changes in this PR are analogous to the Google implementation.

The "done" button text will be replaced by "save". I couldn't find a default "done" text, and I believe "save" to me more expressive anyway.

Hi, thanks a lot for your package; i like it.

DateTime? dateTime = await showOmniDateTimePicker(
      context: viewService.context,
      primaryColor: Colors.cyan,
      backgroundColor: Colors.grey[900],
      calendarTextColor: Colors.white,
      tabTextColor: Colors.white,
      unselectedTabBackgroundColor: Colors.grey[700],
      buttonTextColor: Colors.white,
      timeSpinnerTextStyle:
          const TextStyle(color: Colors.white70, fontSize: 18),
      timeSpinnerHighlightedTextStyle:
          const TextStyle(color: Colors.white, fontSize: 24),
      is24HourMode: true,
      isShowSeconds: false,
      startInitialDate: DateTime.parse(state.dateStr),
      startFirstDate: DateTime(1600).subtract(const Duration(days: 3652)),
      startLastDate: DateTime.now().add(
        const Duration(days: 3652),
      ),
      borderRadius: const Radius.circular(16),
    );

In this mode, the time selection is not centered by default, which makes obsessive-compulsive disorder uncomfortable. Can you fix it or provide custom options, thank you very much

Reproducing code:

final DateFormat workerHistoryDateTimeFormat =
    DateFormat('dd MMMM yyyy - h:mm a');
DateTime date = DateTime.now().toUtc().add(const Duration(hours: -11));

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {

Screenshots:

Expected behavior:

When clicking the button, the time showing by default will be equal to the time on the button, which is 11 hours behind, and should show in UTC as the DateTime date is set to UTC

Actual Behavior:

The time showing by default is equal to the current time and the current timezone.

• Use custom TabView to replace the current TabView in the date_range_picker which requires infinite height and hence BoxConstraints
• Added unselectedTabTextColor
• References Type0N1/OmniDateTimePicker#18

error happens when using package with earlier flutter versions

Hi. Thank you for this library.

I added fix for flutter 3.0 and fix for #6 issue.
