Question 1

react-native-blur or react-native-blurhash for background blur?

Accepted Answer

react-native-blur uses native APIs for real-time, dynamic blur effects ideal for overlays and modals. react-native-blurhash generates static blur placeholders for images, better for loading states. Choose based on whether you need live blurring or pre-rendered placeholders.

Question 2

How to install react-native-blur with Expo?

Accepted Answer

It requires using Expo's config plugins or ejecting for custom native code, as it relies on native modules. For managed Expo projects, consider alternatives like expo-blur, but check compatibility with your Expo version first.

Question 3

Why does vibrancy effect only work on iOS?

Accepted Answer

VibrancyView uses iOS-specific UIVisualEffectView APIs that aren't available on Android. The library prioritizes platform-native implementations, so this feature is limited to iOS for consistency with system behavior.

Question 4

How to fix blur not showing on Android in react-native-blur?

Accepted Answer

Ensure blurAmount is set to 32 or lower, as Android clamps higher values. Verify the BlurView's positioning in the view hierarchy and reinstall native dependencies if integration issues persist.

Question 5

Does react-native-blur support React Native's New Architecture?

Accepted Answer

Compatibility may require updates, as native modules need adaptation. Check the GitHub repository for recent issues or maintainer announcements, as support can vary with React Native versions.

Question 6

How to change blur intensity dynamically in react-native-blur?

Accepted Answer

Update the blurAmount prop via state changes, and use React Native's Animated API for smooth transitions. Note that on Android, values above 32 will be clamped, affecting the intensity range.
