如何在react-native-calendars的项目属性中动态更改日期键的日期

import { Calendar } from 'react-native-calendars';

state = {
  markedDates: {
    '2022-01-01': { marked: true, dotColor: 'red' },
    '2022-02-01': { marked: true, dotColor: 'blue' },
    // 初始的日期键和样式
  }
}

render() {
  return (
    <Calendar
      markedDates={this.state.markedDates}
    />
  );
}

changeDateKey = () => {
  const newMarkedDates = {
    ...this.state.markedDates,
    '2022-01-01': { marked: false }, // 更改日期键的值
    '2022-03-01': { marked: true, dotColor: 'green' }, // 添加新的日期键及样式
  };

  this.setState({ markedDates: newMarkedDates });
}
