.flowconfig file in react-native project is missing

Question

I do not have .flowconfig file in my react-native project.
Even then if I add flow locally as :

yarn add --dev flow-bin babel-preset-flow

and then do flow init, it creates an empty .flowconfig file with the latest flow version displayed at end of the file as 0.79.1 . Is it fine? and the rules I had to copy from https://github.com/facebook/react-native/blob/master/.flowconfig which is regularly updated with current flow version(now 0.79.1).

Or should I not use flow at all in the project, cause may be new version of react-native takes care of it?
