Integrate the Dynatrace React Native Plugin into a React Native or Expo project — dependency setup, dynatrace.config.js, Babel registration, npx instrumentation, navigation tracking, user privacy options, and verification. Handles both bare React Native and Expo (babel-preset-expo) Babel configuration automatically. Trigger: "add Dynatrace to React Native", "React Native plugin setup", "instrument React Native app", "integrate Dynatrace RN", "mobile observability React Native", "react-native-plugin", "dynatrace react native", "add Dynatrace to Expo", "instrument Expo app", "Dynatrace Expo setup". Do NOT use for: querying RN RUM data (use dt-obs-frontends), non-React Native mobile setups, or Dynatrace server-side configuration.
