[V3] Override for isOnline and isDocumentVisible

[xorob0]

Hi everyone 👋

We are setting up a project in React Native that would need to work offline. We saw that the V3 will have offline support, but the implementation of isOnline and isDocumentVisible depend on the browser APIs and would not work on React Native. It would be nice if we could simply override those implementation with our owns when initializing the environment.

I see there is already something similar for the console

Hi @xorob0! This should be possible in V3 with the onlineManager and focusManager instances: https://react-query-beta.tanstack.com/reference/onlineManager

Just tried onlineManager.setOnline(false) manually, but it doesn't affect any of the existing behaviours? Could not find more information in the documentation therefore asked here.

Hi @xmflsct! It should not retry while online is set to false. Do you expect it to do something different?

I played around a bit more, I think it is the most reasonable solution as of now. 👍
