solve the problem of bundle size.

Create a separated component for every single icon
import StarFilled from 'antd/icons/StarFilled';

<StarFilled />
Deprecate reference a icon as a string
A deprecated warning will show when you reference an icon as a string in the following components:

<Icon type="star" />
<Alert iconType="success" />
<Avatar icon="star" />
<Button icon="star" />
Modal.confirm({ iconType: 'star' })
For compatibility, we'll load an SVG sprite on demand when you reference an icon as a string.

Instead of referencing an icon as a string, you should pass ReactNode explicitly to these props:

import StarFilled from 'antd/icons/StarFilled';

<Avatar icon={<StarFilled />} />
