React Native Avatar

The ultimate React Native component for displaying user avatars written in TypeScript with a strong focus on performance. This fully featured and highly customizable component allows you to show Gravatar images by providing an email address, fallback to user's initials, fine-tune the shape and size of avatars, add badges and custom statuses to the avatar image.

---

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.

Badge Component

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.

import React, { useState } from 'react';
import { StyleSheet, Text, TouchableHighlight, View } from 'react-native';
import { Badge } from '@kolking/react-native-avatar';

const MyComponent = () => {
  const [badge, setBadge] = useState(0);

  return (
    <View style={styles.wrapper}>
      <TouchableHighlight
        style={styles.button}
        underlayColor="#00849C"
        onPress={() => setBadge(badge + 1)}
      >
        <>
          <Text style={styles.buttonText}>Press me</Text>
          <Badge value={badge} position="top-right" parentRadius={styles.button.borderRadius} />
        </>
      </TouchableHighlight>
    </View>
  );
};

const styles = StyleSheet.create({
  wrapper: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  button: {
    width: 200,
    height: 44,
    marginTop: 20,
    borderRadius: 22,
    alignSelf: 'center',
    alignItems: 'center',
    justifyContent: 'center',
    backgroundColor: '#2FAFC7',
  },
  buttonText: {
    color: '#fff',
    fontSize: 17,
    fontWeight: '600',
  },
});
