简单的徽章展示，当 count 为 0 时，默认不显示，但是可以使用 showZero 修改为显示。

en-US

Simplest Usage. Badge will be hidden when count is 0, but we can use showZero to show it.

import { ClockCircleOutlined } from '@ant-design/icons';
import { Avatar, Badge } from 'antd';
import React from 'react';

const App: React.FC = () => (
  <>
    <Badge count={5}>
      <Avatar shape="square" size="large" />
    </Badge>
    <Badge count={0} showZero>
      <Avatar shape="square" size="large" />
    </Badge>
    <Badge count={<ClockCircleOutlined style={{ color: '#f5222d' }} />}>
      <Avatar shape="square" size="large" />
    </Badge>
  </>
);

export default App;
