如何将只有一个输入的日期范围添加到react-datepicker

import React, { useState } from 'react';
import DatePicker from 'react-datepicker';
import 'react-datepicker/dist/react-datepicker.css';

function App() {
  const [startDate, setStartDate] = useState(null);

  return (
    <div className="App">
      <h2>Select a Date Range</h2>
      <DatePicker
        selected={startDate}
        onChange={(date) => setStartDate(date)}
        selectsStart
        startDate={startDate}
        endDate={null} // 不设置结束日期
        placeholderText="Select a start date"
      />
    </div>
  );
}

export default App;

<DatePicker
  selected={startDate}
  onChange={(date) => setStartDate(date)}
  selectsStart
  startDate={startDate}
  endDate={null} // 设置为 null
  placeholderText="Select a start date"
/>

import 'react-datepicker/dist/react-datepicker.css';
