REACT SingleDatePicker calendar not opening - reactjs

Question

I am trying to add a drop down calendar but I get warning from the code below and
there is not drop down calendar when cursor was placed over the input box.
Warning from the developer tool, console panel:
VM2542 react-dom.development.js:86 Warning: componentWillReceiveProps has been renamed, and >is not recommended for use. See https://reactjs.org/link/unsafe-component-lifecycles for details.
Move data fetching code or side effects to componentDidUpdate.
If you're updating state whenever props change, refactor your code to use memoization
techniques or move it to static getDerivedStateFromProps. Learn more at: >https://reactjs.org/link/derived-state
Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 18.x, only the UNSAFE_ name will work. To rename all >deprecated lifecycles to their new names, you can run npx react-codemod rename-unsafe->lifecycles in your project source folder.
Please update the following components: DateInput
ExpenseForm.js
import React from "react";
import moment from "moment";
import 'react-dates/lib/css/_datepicker.css'
import 'react-dates/initialize';
import { SingleDatePicker } from "react-dates";
export default class ExpenseForm extends React.Component {
state = {
createdAt: moment(),
calendarFocused: false
}
onDateChange = (createAt) => {
this.setState(()=>({createAt}))
}
onFocusChange = ({focused}) => {
this.setState(()=>{calendarFocused: focused})
}
render(){
return (
<div>
<SingleDatePicker
date={this.state.createdAt} // momentPropTypes.momentObj or null
onDateChange={this.onDateChange} // PropTypes.func.isRequired
focused={this.state.calendarFocused} // PropTypes.bool
onFocusChange={this.onFocusChange} // PropTypes.func.isRequired
numberOfMonths={1}
isOutsideRange={()=>false}
/>
<button>Submit</button>
</div>
)
}
}
I am also getting a hint warning on VSCode on the line:
import 'react-dates/initialize';
Could not find a declaration file for module 'react-dates/initialize'. 'c:/Users/PEI WAI LEE/Programming/ReactCourse/my-provider/node_modules/react-dates/initialize.js' implicitly has an 'any' type.
If the 'react-dates' package actually exposes this module, consider sending a pull request to amend 'https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/react-dates'ts(7016)

Answer 1

I change this line
onFocusChange = ({focused}) => {
this.setState(()=>{calendarFocused: focused})
}
to
onFocusChange = ({focused}) => {
this.setState(()=>({calendarFocused: focused}))
}
without the brackets the statement won't return calendarFocused
The calendar is now showing when I hover the cursor to the input box
can someone advise the warning and the hit warning on VSCode?
