About This Article
React Native developers had to build dark mode support from scratch. They needed to detect color scheme preferences separately for Android and iOS instead of using a shared approach.
React Native added the Appearance module and useColorScheme hook. These tools let developers access user appearance preferences in a consistent way across both platforms.
Developers can now check system color scheme settings and listen for changes with a single API. This removes the need for platform-specific code and makes the implementation simpler.
