Summary:
This is fixing #8615. The problem was that, on initialization, the `_connectionType` variable was still set to its default value of `RCTConnectionTypeUnknown`. The exposed API method did nothing to determine this unless a subscription had be established and then the method would simply return the last reported value. Instead, the exposed oneshot API call now actually checks the connection status through the same methods as the subscription and updates RCTNetInfo’s values before returning.
In order to avoid reporting events without a subscription, a flag is set and unset on calls to start/stopObserving.
- start app
- observe the (in)correct reporting of the manual status
- change network status to offline
- press refresh
- observe the manual fetch
- start subscription
- change network status to online
- press refresh to show that the manual refresh works (only now working for current RN version)
- change network status to offline
- stop subscription
- change network status to online
- press refresh to show manual refresh does(n't) work without subscription
- start subscription to show it updates to current
