当用户使用react-dates键入过去的日期时，onDateChange返回null

import React, { useState } from 'react';
import { SingleDatePicker } from 'react-dates';
import 'react-dates/initialize';
import 'react-dates/lib/css/_datepicker.css';

const App = () => {
  const [date, setDate] = useState(null);

  const handleDateChange = (selectedDate) => {
    setDate(selectedDate);
  };

  const isOutsideRange = (selectedDate) => {
    return false; // 允许选择过去的日期
  };

  return (
    <div>
      <SingleDatePicker
        date={date}
        onDateChange={handleDateChange}
        isOutsideRange={isOutsideRange}
        focused={true}
        numberOfMonths={1}
      />
    </div>
  );
};

export default App;
