import DatePicker from 'react-native-date-picker';

 const [date, setDate] = useState(new Date());
  const [dateForEndDate, setDateForEndDate] = useState(new Date());
  const [open, setOpen] = useState(false);
  const [openForEndDate, setOpenForEndDate] = useState(false);


  {/* {dealprice === '' || ( */}
            <TouchableOpacity onPress={() => setOpen(true)}>
              <View
                style={{
                  width: wp('75%'),
                  flexDirection: 'row',
                  backgroundColor: '#F2F3F5',

You will need to have a single Datepicker at the end of the component and you just need to handle that what cause this picker to open ie Start Date or End Date. Here is code example

  import moment from 'moment'
   .... 
  const DateFormat = "DD/MM/YYYY";
  const [startDate, setStartDate] = 
  useState(moment().format(DateFormat))
 const [endDate, setEndDate] = useState(moment().add(1, 
 'year').format(DateFormat))
 const [dateVisible, setDateVisibleState] = useState(0) // 0-hide , 1-start 
 //date, 2-end date
 const dateVisibleRef = useRef(0)
 const setDateVisible = (val) => {
 dateVisibleRef.current = val
 setDateVisibleState(val)
 }
 const [calendarDate, setCalendarDate] = useState(new Date())

 ....
 
  <DateTimePicker
    modal
    mode="date"
    open={dateVisibleRef.current > 0}
    date={calendarDate}
    onDateChange={setCalendarDate}
    onConfirm={(date) => {
      let state = dateVisibleRef.current
      setDateVisible(0)
      if (state == 1)
        setStartDate(moment(date).format(DateFormat))
      else if (state == 2)
        setEndDate(moment(date).format(DateFormat))
    }}
    onCancel={() => {
      setDateVisible(0)
    }}
  />
