Complete usage example that works on iOS and Android:

`javascript
import React, { Component } from "react";
import { View, Image, Text, StyleSheet } from "react-native";
import { BlurView } from "@react-native-community/blur";

export default function Menu() {
return (

key={'blurryImage'}
source={{ uri }}
style={styles.absolute}
/>
Hi, I am some blurred text
{/ in terms of positioning and zIndex-ing everything before the BlurView will be blurred /}
style={styles.absolute}
blurType="light"
blurAmount={10}
reducedTransparencyFallbackColor="white"
/>
I'm the non blurred text because I got rendered on top of the BlurView

)
}

const styles = StyleSheet.create({
container: {
justifyContent: "center",
alignItems: "center"
},
absolute: {
position: "absolute",
top: 0,
left: 0,
bottom: 0,
right: 0
}
});
`

In this example, the Image component will be blurred, because the BlurView in positioned on top. But the Text will stay unblurred.

If the accessibility setting Reduce Transparency is enabled the BlurView will use reducedTransparencyFallbackColor as it's background color rather than blurring. If no reducedTransparencyFallbackColor is provided, theBlurViewwill use the default fallback color (white, black, or grey depending on blurType)

$3

Uses the same properties as BlurView (blurType, blurAmount, and reducedTransparencyFallbackColor).

The vibrancy effect lets the content underneath a blurred view show through more vibrantly

VibrancyView is only supported on iOS. Also note that the VibrancyView must contain nested views

`javascript
import { VibrancyView } from "@react-native-community/blur";

export default function Menu() {
return (


Hi, I am some vibrant text.


)
}
