[Question]: Issue in Flutter Application with Wi-Fi Connectivity on iOS

[srisudhanl]

What is your question?

I am developing a Flutter application that:

• Checks for Wi-Fi connectivity and displays the details to the user in a dialog.

Behavior Observed:

• On Android, the application works perfectly, even when connected to a Wi-Fi network without internet access.
• On iOS, the application behaves unexpectedly:
  • When connected to a Wi-Fi network with internet access, it works as expected.
  • When connected to a Wi-Fi network without internet access, the results are incorrect. (always showing as none. But Wi-Fi is connected to the mobile).

Details:
I am using the following packages for checking Wi-Fi connectivity:

1. connectivity_plus
2. network_info

Both packages lead to unexpected results when testing on iOS.

Question:
How can I resolve this issue or achieve reliable Wi-Fi connectivity detection, especially for Wi-Fi networks without internet access, on iOS?

When connected to a Wi-Fi network without internet access, the results are incorrect. (always showing as none. But Wi-Fi is connected to the mobile).

I assume this is Connectivity Plus saying that connectivity is none even when the WiFi connectivity appears on the device status bar, right?

It could be that the device disconnects from wifi and forces to use the phone network if it detects no internet connectivity.

iOS (and macOS) use NWPathMonitor to obtain the connectivity status, so that's something you can research and see why NWPathMonitor does not report wifi if there is no internet connection.

The code:

plus_plugins/packages/connectivity_plus/connectivity_plus/darwin/connectivity_plus/Sources/connectivity_plus/PathMonitorConnectivityProvider.swift

Line 12 in 2d69758

private func connectivityFrom(path: NWPath) -> [ConnectivityType] {

same happenes on simulator after second wifi turn off and turn on , onConnectivityChanged is not fired and checkConnectivity method gives none response.

in the README you can find the following information:

On iOS simulators, the connectivity types stream might not update when Wi-Fi status changes. This is a known issue.
