### What is the current behaviour?

I have got transform error while implementing mobx support for flow runtime in react native ios,
it is:

> error: bundling failed: "TransformError: /../../node_modules/react-native/Libraries/Renderer/shims/ReactNativeTypes.js:/../../node_modules/react-native/Libraries/Renderer/shims/ReactNativeT.ypes.js: Property value expected type of string but got null"

### What is the expected behaviour?

- It has to work like mentioned here:
_https://codemix.github.io/flow-runtime/#/flow-runtime-mobx_

Have looked into this, https://github.com/codemix/flow-runtime/issues/17 tried solutions suggested by @phpnode and @skovhus and others, but no progress 👎
