React Native Windows: value except only Date as object, onchange not triggered if unselect date

[kurpiel]

Bug report

Summary

datetimepicker.windows.js

1. I want to set undefined or null as date value but it is prevented by validation. If i comment that line eveything is working fine.
2. If unselect the date in the datepicker by clicking on the current selected date, the onChange Event is never fired. So i never know how the state of the picker is.

Reproducible sample code

<DateTimePicker
      style={styles.datePicker}
      value={null} // NOT POSSIBLE to set NULL
      display="calendar"
      firstDayOfWeek={1}
      onChange={(event: DateTimePickerEvent, date?: Date) => {
          // NOT FIRED if unselect the date
      }}
      onError={(arg: Error) => console.log('GKU Date Error', arg)}/>

Steps to reproduce

--

Describe what you expected to happen:

1. Null as initial value should be allows
2. Validation for value in utils.js should be removed because it is already checked. And if i remove the init validation (sharedPropsValidation) everything works fine:

export default function RNDateTimePickerQWE(
  props: WindowsNativeProps,
): React.Node {
  sharedPropsValidation({value: props?.value}); // **REMOVING THIS LINE FIXES THE ISSUE** 

  const localProps = {
    dayOfWeekFormat: props.dayOfWeekFormat,
    dateFormat: props.dateFormat,
    firstDayOfWeek: props.firstDayOfWeek,
    maxDate: props.maximumDate ? props.maximumDate.getTime() : undefined, // time in milliseconds
    minDate: props.minimumDate ? props.minimumDate.getTime() : undefined, // time in milliseconds
    onChange: props.onChange,
    placeholderText: props.placeholderText,
    selectedDate: props.value ? props.value.getTime() : undefined, // time in milliseconds
    style: [styles.rnDatePicker, props.style],
  };
