Upgrading from 4.0.0-beta27 to 4.0.0 breaks app

I am attempting to upgrade my app from 4.0.0-beta27 to 4.0.0 but it seems to break from an internal error:

What is context.changedBits and where can I find it? This seems to be what is breaking everything. Note that the app errors instantly upon opening.

As discussed here, this is because of the new context API. I can't say much, cause I don't know anything about your environment, but try to use React > 16 and React Native > 0.55.

Probably we will need to update README to say that as well.

I am already on React ^16.4.2 but updating from React Native 0.54.0 to 0.55.0 doesn't seem to want to play nice. I get React Native version mismatch even after resetting cache with:

react-native-scripts start --reset-cache

Any ideas, @daviscabral?

[dextermb]

In reference to updating README, I think that most of the documentation around this package needs updating. For example in the latest versions there's an onStateChange prop for Router but it's not documented (and I bet this is one that people ask about a lot).

[daviscabral]

React Native 0.55 does not support React 16 as you can see here https://github.com/facebook/react-native/blob/v0.55.4/package.json#L145.

Please provide failing example (with valid package versions).

For docs, PRs are welcome. The upgrade for React Navigation is pretty recent.
