Demo App

Usage

TextButton(
    onPressed: () {
        DatePicker.showDatePicker(context,
                              showTitleActions: true,
                              minTime: DateTime(2018, 3, 5),
                              maxTime: DateTime(2019, 6, 7), onChanged: (date) {
                            print('change $date');
                          }, onConfirm: (date) {
                            print('confirm $date');
                          }, currentTime: DateTime.now(), locale: LocaleType.zh);
    },
    child: Text(
        'show date time picker (Chinese)',
        style: TextStyle(color: Colors.blue),
    ));

Customize

If you want to customize your own style of date time picker, there is a class called CommonPickerModel, every type of date time picker is extended from this class, you can refer to other picker model (eg. DatePickerModel), and write your custom one, then pass this model to showPicker method, so that your own date time picker will appear, it’s easy, and will perfectly meet your demand

How to customize your own picker model:

class CustomPicker extends CommonPickerModel {
  String digits(int value, int length) {
    return '$value'.padLeft(length, "0");
  }

  CustomPicker({DateTime currentTime, LocaleType locale}) : super(locale: locale) {
    this.currentTime = currentTime ?? DateTime.now();
    this.setLeftIndex(this.currentTime.hour);
    this.setMiddleIndex(this.currentTime.minute);
    this.setRightIndex(this.currentTime.second);
  }

  @override
  String leftStringAtIndex(int index) {
    if (index >= 0 && index < 24) {
      return this.digits(index, 2);
    } else {
      return null;
    }
  }

  @override
  String middleStringAtIndex(int index) {
    if (index >= 0 && index < 60) {
      return this.digits(index, 2);
    } else {
      return null;
    }
  }

  @override
  String rightStringAtIndex(int index) {
    if (index >= 0 && index < 60) {
      return this.digits(index, 2);
    } else {
      return null;
    }
  }

  @override
  String leftDivider() {
    return "|";
  }

  @override
  String rightDivider() {
    return "|";
  }

  @override
  List<int> layoutProportions() {
    return [1, 2, 1];
  }

  @override
  DateTime finalTime() {
    return currentTime.isUtc
        ? DateTime.utc(currentTime.year, currentTime.month, currentTime.day,
            this.currentLeftIndex(), this.currentMiddleIndex(), this.currentRightIndex())
        : DateTime(currentTime.year, currentTime.month, currentTime.day, this.currentLeftIndex(),
            this.currentMiddleIndex(), this.currentRightIndex());
  }
}

Custom title bar

By default every picker shows a Cancel/Done bar above the wheels. Pass a titleActionsBuilder to any DatePicker.show* method to replace it with your own widget. The builder receives onCancel / onConfirm callbacks (which dismiss the picker the same way the default buttons do) and the currently selected DateTime:

DatePicker.showDatePicker(
  context,
  titleActionsBuilder: (context, onCancel, onConfirm, currentTime) {
    return Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: [
        TextButton(onPressed: onCancel, child: const Text('Close')),
        Text('${currentTime.year}-${currentTime.month}-${currentTime.day}'),
        TextButton(onPressed: onConfirm, child: const Text('Pick')),
      ],
    );
  },
);

The bar is laid out within the theme's titleHeight, so keep your widget within that height (or raise titleHeight via a custom DatePickerTheme). The builder is only used when showTitleActions is true (the default).
