[Bug]: onConnectivityChanged - iOS not showing when WiFi is not available
Platform
iOS 16.4 simulator
Plugin
connectivity_plus
Version
^4.0.2
Flutter SDK
3.10.6
Steps to reproduce
- Run App with WiFi turned on
- Turn off WiFi
-
onConnectivityChangedstill shows 'wifi' instead of 'none' for internet connection
But if you do the following it works ok but will break again:
Run the App with WiFi turned off Turn on the WiFi on Mac (it works) Turn off the WifFi on Mac onConnectivityChanged still shows 'wifi' instead of 'none' for internet connection
Code Sample
connectionService.connectivity.onConnectivityChanged
.listen((connectivityResult) {
debugPrint('connectivityResult: ${connectivityResult.name}');
});
By the way, when you run it on an actual iPhone device it looks like it's working fine.

This is an issue with iOS simulators. As long as it works on a real device, there is nothing to fix.
It is the same case as with network_info_plus plugin where wifiInfo will always return null on simulator even when the project has all the required entitlements, configs.
I will update the documentation with this note, though.
In fact, it turns out that it is already mentioned in the first sentence under iOS section: https://github.com/fluttercommunity/plus_plugins/tree/main/packages/connectivity_plus/connectivity_plus#ios
