React Native Ignite: Building an AI app
summary
A working Expo React Native app that scans documents using react-native-mlkit document scanner and Google on-device ML Kit, detects rectangles, crops/rotates, removes shadows and offers a magic-eraser; the module returns a result URI and supports multi-page and gallery import options. The hard math (homographies via a 4x4 matrix) is handled by the library so only a few lines of code are needed. Live demo succeeds on Android (document scanner beta); iOS support is pending.
