No dimensions set for key window
react-native
Solution
There apparently is an issue with `react-router-flux` since a few days.
You probably need to rollback to the `3.38.0` version before the bug was introduced.
yarn add react-native-router-flux@3.38.0
If it doesn't work, some people also said that you might need to close all your terminals, delete your build folder and clear your npm cache.
Problem
I am having some issues with react native. It keeps giving me the following error. What could be causing this?
