A universal React component that renders a gradient view.
expo-linear-gradient
provides a native React view that transitions between multiple colors in a linear direction.

npx expo install expo-linear-gradient
If you are installing this in an existing React Native app, start by installing expo
in your project. Then, follow the additional instructions as mentioned by the library's README under "Installation in bare React Native projects" section.
import { StyleSheet, Text, View } from 'react-native';
import { LinearGradient } from 'expo-linear-gradient';
export default function App() {
return (
<View style={styles.container}>
<LinearGradient
// Background Linear Gradient
colors={['rgba(0,0,0,0.8)', 'transparent']}
style={styles.background}
/>
<LinearGradient
// Button Linear Gradient
colors={['#4c669f', '#3b5998', '#192f6a']}
style={styles.button}>
<Text style={styles.text}>Sign in with Facebook</Text>
</LinearGradient>
</View>
);
}
const styles = StyleSheet.create({

flex: 1,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: 'orange',

LinearGradient
Type: React.Component<LinearGradientProps>
Renders a native view that transitions between multiple colors in a linear direction.
colors
readonly
A readonly array of colors that represent stops in the gradient. At least two colors are required
(for a single-color background, use the style.backgroundColor
prop on a View
component).
dither
boolean
• Default: true
Enables or disables paint dithering. Dithering can reduce the gradient color banding issue.
Setting false
may improve gradient rendering performance.
end
LinearGradientPoint | null
For example, { x: 0.1, y: 0.2 }
means that the gradient will end 10%
from the left and 20%
from the bottom.
On web, this only changes the angle of the gradient because CSS gradients don't support changing the end position.
locations
readonly | null
• Default: []
A readonly array that contains number
s ranging from 0
to 1
, inclusive, and is the same length as the colors
property.
Each number indicates a color-stop location where each respective color should be located.
If not specified, the colors will be distributed evenly across the gradient.
For example, [0.5, 0.8]
would render:
The color-stop locations must be ascending from least to greatest.
start
LinearGradientPoint | null
For example, { x: 0.1, y: 0.2 }
means that the gradient will start 10%
from the left and 20%
from the top.
On web, this only changes the angle of the gradient because CSS gradients don't support changing the starting position.
LinearGradientPoint
An object { x: number; y: number }
or array [x, y]
that represents the point
at which the gradient starts or ends, as a fraction of the overall size of the gradient ranging
from 0
to 1
, inclusive.
Type: NativeLinearGradientPoint
or object shaped as below:
Name | Type | Description |
---|---|---|
x | number | A number ranging from |
y | number | A number ranging from |
