Description

addEventListener triggers only for the first time/ first couple times that connection changes. After that it doesn’t trigger the event.

Reproducible Demo

Use following code:

  useEffect(() => {
     NetInfo.addEventListener((networkState) => {console.log(networkState)}
  }, [])

Try to switch the wifi on and off for more than 4-5 times. See if it triggers all the events.

@mhatami-ecotrak Are you able to reproduce this bug on a physical device? I tried your demo on a simulator, and it was buggy, but I could not reproduce it on a physical device.

(You will have to run the app from Xcode and watch the logs there because you’ll get disconnected from the Metro server doing this test)

@mikehardy V6 didn’t work either.
