老师，根据课程把 todolistui 拆出来后，报了这个错误，还请老师指点一二。

代码

import React, {Component} from 'react';
import {getInputChangeAction, addTodoItemAction, deleteTodoItemAction} from './store/actionCreators';
import store from './store/index.js';
import TodoListUI from './TodoListUI';

class TodoList extends Component {
    constructor(props){
        super(props);
        this.state = store.getState();
        this.handleInputChange = this.handleInputChange.bind(this);
        this.handleStoreChange = this.handleStoreChange.bind(this);
        this.handleBtnClick = this.handleBtnClick.bind(this);
        this.handleDeleteItem = this.handleDeleteItem.bind(this);
        store.subscribe(this.handleStoreChange);
    }

    render(){
        return (
            <TodoListUI
                inputValue={this.state.inputValue} 
                list={this.state.list}
                handleInputChange={this.handleInputChange}  
                handleBtnClick={this.handleBtnClick}
                handleDeleteItem={this.handleDeleteItem}
            />
        )
    }
    handleInputChange(e){
        const action = getInputChangeAction(e.target.value);
        store.dispatch(action);

    }

    handleStoreChange(){
        this.setState(store.getState());
    }
    handleBtnClick(){
        const action = addTodoItemAction();
        store.dispatch(action);
    }

    handleDeleteItem(index){
        const action =deleteTodoItemAction(index);
        store.dispatch(action);
    }
}

export default TodoList

import React, {Component} from 'react';
import 'antd/dist/antd.css';

                <Button onClick={this.props.handleBtnSubmit} type="primary">Submit</Button>
