react-native-linear-gradient is a mature, well-maintained React Native library that provides a `<LinearGradient>` component for rendering linear gradients on iOS and Android. The library supports both the old (Paper) and new (Fabric) React Native architectures, with native implementations in Objective-C/C++ (iOS) and Java (Android). It offers configurable start/end points, color stops, angle-based gradients, and automatic handling of border radii on Android. The codebase is cleanly structured with TypeScript types, proper prop validation, and a Jest mock for testing. The example app demonstrates various use cases including simple gradients, angle gradients, animated gradient transitions, and gradient buttons. The library is actively maintained with CI/CD pipelines, recent commits, and support for React Native 0.75+.
