**Control the shape of the avatars**  
The default circular shape can be changed by specifying a custom border radius. The `style` prop enables you to override the default styles.

**Custom fallback image or emoji**  
For users without an image, you have the option to display the default avatar icon, provide a custom fallback image, or even show an emoji.

**Fallback to user's initials**  
Another option for users without an image is to display their initials. By enabling the `colorize` option, unique color can be generated based on the user's name.

**Gravatar support**  
Include the user's email address to display their Gravatar image. This can be combined with your own avatar image to provide a fallback option.

**Numeric badges**  
You can add a badge to display the count of unread messages or the online/offline status of the user. The position of the badge can also be customized.

**Custom badges**  
Another option for utilizing avatar badges is to display a custom status icon, such as an emoji, for example.

`color` | string | `#aeaeb2` | Background color of the avatar
`radius` | number | `size / 2` | Border radius of the avatar

## Badge Component

<img width="200" align="left" src="https://github.com/kolking/react-native-avatar/assets/4656448/6ee48b43-d2ac-40bb-ab21-152a93637e4a" />

The badge can be used as a standalone component. The font size of the badge text value is calculated based on the `size` prop, so you normally don't have to specify it. By default, the badge appears with a spring animation, which can be disabled using the `animate` prop. To position the badge absolutely over its parent, use the `position` prop along with the `parentRadius` prop.
