[Peter Tan]

The code is here, but I just report an error ， Did I make a mistake? Can you tell me
代码如下，就是会报错：

Element type is invalid ，

import React from 'react';
import { DynamicSizeList as List } from 'react-window';
import AutoSizer from 'react-virtualized-auto-sizer';

const Row = ({ data, index, style }) => (
  <div className={index % 2 ? 'ListItemOdd' : 'ListItemEven'} style={style}>
    {index}
  </div>
);

class App extends React.PureComponent{
     render(){
       return (
          <AutoSizer>
             {({ width, height }) => (
              <List
                width={width}
                height={height}
                className="msgList"
                itemCount={20}
              >
                {Row}
              </List>
            )}
          </AutoSizer>
)
}
}

export default App;
