Combining icons

You can combine multiple icons into a single icon by using SVG in SVG. This is useful for if you want to be creative and make your own custom icons by combining existing icons.

import React, {useState, useEffect} from 'react';
import { View, StyleSheet } from 'react-native';
import { Scan, User} from "lucide-react-native";

const App = () => {
  return (
    <View style={styles.container}>
      <Scan size={48}>
        <User
          size={12}
          x={6}
          y={6}
          absoluteStrokeWidth
        />
      </Scan>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    height: '100%',
    alignItems: 'center',
    display: 'flex',
    justifyContent: 'center'
  },
});

export default App;

This is valid SVG and all SVG properties are supported on the icons. The x and y coordinates can be adjusted to position the icons as you like.

Caveats

When combining icons, you need to make sure that the icon you is in the viewBox of the outer icon (24x24).

With custom SVG elements

You can also use SVG elements to create your own icons.

Example with notification badge

import React, {useState, useEffect} from 'react';
import { View, StyleSheet } from 'react-native';
import { Mail } from "lucide-react-native";
import { Circle } from 'react-native-svg';

const App = () => {
  const hasUnreadMessages = true;

  return (
    <View style={styles.container}>
      <Mail size={48}>
        {hasUnreadMessages && (
          <Circle
            r="3"
            cx="21"
            cy="5"
            stroke="none"
            fill="#F56565"
          />
        )}
      </Mail>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    height: '100%',
    alignItems: 'center',
    display: 'flex',
    justifyContent: 'center'
  },
});

export default App;

Example with text element

You can also use the text SVG element to add text to your icon.

import React, {useState, useEffect} from 'react';
import { View, StyleSheet } from 'react-native';
import { File } from "lucide-react-native";
import { Text } from 'react-native-svg';

const App = () => {
  const hasUnreadMessages = true;

  return (
    <View style={styles.container}>
      <File size={48}>
        <Text
          x={7.5}
          y={19}
          fontSize={8}
          fontFamily="Verdana,sans-serif"
          strokeWidth={1}
        >
          JS
        </Text>
      </File>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    height: '100%',
    alignItems: 'center',
    display: 'flex',
    justifyContent: 'center'
  },
});

export default App;
