# Combining icons
|
|
|
|
You can combine multiple icons into a single icon by nesting SVG elements.
|
|
This is useful if you want to create custom icons by combining existing ones.
|
|
|
|
```SnackPlayer name=State&ext=js&dependencies=react-native-svg,lucide-react-native
|
|
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} nonScalingStroke>
|
|
<User
|
|
size={12}
|
|
x={6}
|
|
y={6}
|
|
nonScalingStroke
|
|
/>
|
|
</Scan>
|
|
</View>
|
|
);
|
|
};
|
|
|
|
const styles = StyleSheet.create({
|
|
container: {
|
|
height: '100%',
|
|
alignItems: 'center',
|
|
display: 'flex',
|
|
justifyContent: 'center'
|
|
},
|
|
});
|
|
|
|
export default App;
|
|
```
|
|
|
|
This is valid, since [SVGs can be nested](https://developer.mozilla.org/en-US/docs/Web/SVG/Reference/Element/svg#nested_svg_element), and all SVG properties are supported on the icons.
|
|
The `x` and `y` coordinates can be adjusted to position the icons as you like.
|
|
|
|
::: info Limitation
|
|
When combining icons, you need to make sure that the `x` and `y` coordinates are within the `viewBox` of the outer icon (24x24).
|
|
:::
|
|
|
|
## With native SVG elements
|
|
|
|
You can also combine Lucide icons with native SVG elements to build custom icon variations.
|
|
|
|
### Example with notification badge
|
|
|
|
For example, you can add a notification badge to an icon by using the `circle` SVG element.
|
|
|
|
```SnackPlayer name=State&ext=js&dependencies=react-native-svg,lucide-react-native
|
|
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.
|
|
|
|
```SnackPlayer name=State&ext=js&dependencies=react-native-svg,lucide-react-native
|
|
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;
|
|
```
