Same issue here, we do listen to .onConnectivityChanged events on many occasions, and since the migration from connection: 3.0.2 to connection_plus: 5.0.2 iOS app version does briefly report ConnectivityResult.none, to then follow up with actual connection state, e.g. ConnectivityResult.wifi. The incorrect .none report only happens for subsequent stream requests, first one works correctly.

Above issue was observed on iPadOS 15.8.1 and iOS 17.3, Flutter SDK 3.16.7. Issue does not affect Android.
