 From [`Debugging using a custom JavaScript debugger`](https://facebook.github.io/react-native/docs/debugging.html#debugging-using-a-custom-javascript-debugger) of React Native docs, you can use `REACT_DEBUGGER` env on react-native packager, it will try to launch RNDebugger when you turn on `Debug JS Remotely`.
