React Native Screens Adds Split View Support, 4.17.0 Released#
React Native Screens is planning to add Split View support for iPad. Since React Native Screens is used by React Navigation and Expo Router (which uses React Navigation internally), we can expect those libraries to gain Split View support down the line as well.
React Native Screens will provide Native Split View 🚀 Coming soon to your favorite navigation libraries!

react-native-mmkv v4 Is Here#

set(...)does not succeed - MMKVCore upgraded for faster performance

- Bug fixes
React Native Bottom Tabs 1.0.0 is out ✨ - Drops old architecture 🌅 - Simplifies build configuration, making it fully compatible with Expo Image ✅ - Bunch of bug fixes 🐛 It works with @expo router, @reactnavigation and in standalone mode ⬇️
Skia Template Added to create-expo#
A new template using Skia and Expo Router has been added to npx create-expo for bootstrapping Expo projects.
Created a new starter for using Skia with Expo Router: ~ / npx create-expo -e with-skia This uses suspense to load skia on web so all UI state lives in React.
LegendList 2.0.12 and 2.1.0-beta#
LegendList 2.0.12 brings even more performance improvements. Compared to FlatList and FlashList2, it appears to scroll more smoothly with fewer blank areas showing up.
LegendList 2.0.12 is much faster than earlier versions, so I recommend updating ❤️ It now runs tighter loops, does less math, and better uses scroll velocity to predict what will be in view next frame. So it leaves more frame time for your components to render ✨ twitter.com/jmeistrich/status/…
2.1.0-beta2 is also out. This version adds support for infinite scrolling on the Web, along with scrollToIndex and StickyHeader functionality.
I've got LegendList's scrollToIndex and sticky headers features working in react-dom now (though not fully optimized yet) - try it out in @legendapp/[email protected] 🎉 If you've used another web virtualized list library before, what are your pain points?
Uniwind RC1#
Uniwind RC1, which lets you style your app with a Tailwind-like API, has been released. It’s reportedly twice as fast as the previous beta.
I'm thrilled to announce that Uniwind has reached its first RC and it's faaaast 🔥
