Create iOS Translucent Headers in React Native with Expo Progressive Blur

Description:

Expo Progressive Blur is a React Native component that recreates the modern, layered, and translucent headers found in native iOS applications like Settings, Wallet, and Music.

Features

• 📱 Native iOS Feel: Implements the signature Apple-style translucent and blurred header effect for a polished user experience.
• 🌀 Progressive Animations: Utilizes react-native-reanimated to animate header properties like blur, opacity, and scale in response to scroll events.
• 🎨 Gradient Masking: Employs a masked view with linear gradients to create smooth transitions that reveal the blurred content below.
• 🧩 Composable Tech Stack: Built with a collection of well-regarded libraries including expo-blur, expo-linear-gradient, and expo-symbols.
• 💨 Smooth Transitions: Incorporates soft spring animations for fading elements, which contributes to a fluid and responsive interface.

Use Cases

• Settings Screens: Replicate the native iOS Settings app header, where the title collapses and the background blurs as you scroll through options.
• Music & Media Apps: Create dynamic headers for playlists or artist pages that blur album art or other background images during scroll.
• Profile Pages: Design user profile screens where a large profile picture in the header progressively blurs as the user scrolls through details.
• Content Feeds: Apply the effect to social media or news feeds to maintain a visible, yet unobtrusive, header as content scrolls beneath it.
• Wallet & Finance Apps: Mimic the Apple Wallet interface, where cards or passes scroll behind a translucent, blurred header.
