React native 如何使用React Native calendar将事件添加到应用程序内日历？

我已经使用react native calendar构建了一个应用程序内日历，我希望用户能够在日历中添加或删除约会，但无法理解这一部分。用户最多可以提前一周安排。我该怎么做

以下是生成日历的代码：

import { Calendar, CalendarList, Agenda } from 'react-native-calendars';

const ScheduleScreen = ({navigation}) => {

const numWeeks = 1
const weekAhead = new Date; weekAhead.setDate(weekAhead.getDate()+ numWeeks * 7)

const [ item, setItem ] = useState({});

return(
....

<Agenda
          onDayPress = {(day)=>console.log('Day changed')}
          minDate = {new Date()}
          maxDate = {weekAhead}
          pastScrollRange = {0}
          futureScrollRange = {0}
        
          items = {{
            'new Date()': [],
            weekAhead: [],
          }}
        
        />
....

)
}

从'react native calendars'导入{Calendar，CalendarList，Agenda}；
const ScheduleScreen=（{navigation}）=>{
常数numWeeks=1
const weekahed=新日期；weeKahed.setDate（weeKahed.getDate（）+numWeeks*7）
const[item，setItem]=useState（{}）；
返回(
....
console.log（'Day changed'）}
minDate={new Date（）}
maxDate={weekAhead}
pastScrollRange={0}
未来滚动范围={0}
项目={{
“新日期（）”：[]，
weekAhead:[]，
}}
/>
....
)
}
