react-native-sfsymbol v0.3.0

react-native-sfsymbol

NOTE: This library is under development, so the API may change until it hits v1.0.0.

SF Symbols are a set of over 2,500 consistent, highly configurable symbols you can use in your app. SF Symbols are designed to integrate seamlessly with the San Francisco system font, so the symbols automatically ensure optical vertical alignment with text for all weights and sizes.

Highlights

• :fire: Built with Expo's Module API
• :art: Support for all rendering modes
• :loud_sound: Support for variable color values
• :apple: iOS only (see why)

Installation

Add the package as a dependency

yarn add react-native-sfsymbol

Then run

npx pod-install

NOTE: This library works with bare React Native and Expo managed apps. It will not work with Expo Go.
