在React Native日历选择器中，我想通过提供一个函数来禁用某些日期

import React, { useState } from 'react';
import { Calendar } from 'react-native-calendars';

const disabledDates = ['2022-12-25', '2023-01-01']; // 要禁用的日期列表

const CalendarPicker = () => {
  const [selectedDate, setSelectedDate] = useState(null);

  // 函数用于检查日期是否被禁用
  const isDateDisabled = (date) => {
    return disabledDates.includes(date.dateString);
  };

  // 当日期被选择时的处理函数
  const handleDateSelect = (date) => {
    setSelectedDate(date.dateString);
  };

  return (
    <Calendar
      markedDates={{ [selectedDate]: { selected: true } }}
      onDayPress={handleDateSelect}
      dayComponent={({ date, state }) => {
        const isDisabled = isDateDisabled(date);
        return (
          <View style={{ opacity: isDisabled ? 0.5 : 1 }}>
            <Text>{date.day}</Text>
          </View>
        );
      }}
    />
  );
};

export default CalendarPicker;
