BlurView

A React component that blurs everything underneath the view. On iOS, it renders a native blur view. On Android, it falls back to a semi-transparent view. Common usage of this is for navigation bars, tab bars, and modals.

Usage

Basic BlurView usage

import { Text, StyleSheet, View, SafeAreaView } from 'react-native';
import { BlurView } from 'expo-blur';

export default function App() {
  const text = 'Hello, my container is blurring contents underneath!';
  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.background}>
        {[...Array(20).keys()].map((i) => (
          <View
            key={`box-${i}`}
            style={[styles.box, i % 2 === 1 ? styles.boxOdd : styles.boxEven]}
          />
        ))}
      </View>
      <BlurView intensity={100} style={styles.blurContainer}>
        <Text style={styles.text}>{text}</Text>
      </BlurView>
      <BlurView intensity={80} tint="light" style={styles.blurContainer}>
        <Text style={styles.text}>{text}</Text>
      </BlurView>
      <BlurView intensity={90} tint="dark" style={styles.blurContainer}>
        <Text style={[styles.text, { color: '#fff' }]}>{text}</Text>
      </BlurView>
    </SafeAreaView>
  );
