React Native version mismatch.

have been encountering a lot “react native version mismatch” isuse:

console.error: "React Native version mismatch.

JavaScript version: 0.59.8
Native version: 0.57.1

Make sure that you have rebuilt the native code. If the problem persists try clearing the Watchman and packager caches with `watchman watch-del-all && react-native start --reset-cache`."

few steps to resolve these:

1. update the expo and react native to updated and matching versions
2. remove all node_modules
3. re-run npm install
4. kill the simulator (this would make sure the expo start update the expo client)
5. expo start -c
