Skia multiplatform demo 👋

This is an Expo project created with create-expo-app, and can be built for web, mobile devices (iOS, iPadOS, and Android), and TV devices (Apple TV, Android TV).

You can see the web version at

https://skiamultiplatform.expo.app/

This project uses

• the React Native TV fork, which supports both phone (Android and iOS) and TV (Android TV and Apple TV) targets
• the React Native TV config plugin to allow Expo prebuild to modify the project's native files for TV builds
• the Shopify react-native-skia package to render high performance 2D graphics.
• the victory-native package, which uses Skia for charting and graphing data.
• the expo-router native tabs experimental feature in Expo SDK 54.

This app includes the following demos from the react-native-skia examples:

• Breathe
• Glassmorphism
• Reanimated

For mobile and TV, this app includes the following demos from the victory-native examples:

• Line Chart
• Bar Chart

The demos have been slightly modified to render and size correctly on TV, and resize correctly on iPad screen rotations.
