reactPropTypes怎么校验传递的值

import React, { Component, Fragment } from 'react';
import List from './List.js';
 
class Test extends Component {
  constructor(props) {
    super(props);
    this.state={
      inputValue:'aaa',
      list:['睡觉','打游戏'],
    }
    // this.add=this.add.bind(this);
  }
 
  addList() {
    this.setState({
      list:[...this.state.list,this.state.inputValue],
      inputValue:''
    })
  }
 
  change(e) {
    this.setState({
      inputValue:e.target.value
    })
  }
 
  delete(i) {
    // console.log(i);
    const list = this.state.list;
    list.splice(i,1);
    this.setState({
      list:list
    })
  }
 
  render() { 
    return (
      <Fragment>
      <div>
        <input value={this.state.inputValue} onChange={this.change.bind(this)}/>
        <button onClick={this.addList.bind(this)}>添加</button>
      </div>
      <ul>
        {
          this.state.list.map((v,i)=>{
            return(
                <List key={i} content={v} index={i} delete={this.delete.bind(this)} />
            );
          })
        }
      </ul>
      </Fragment>
    );
  }
}
export default Test;

//设置默认值：
