[Bug]: network_info_plus NetworkInfo().getWifiIP() returns incorrect IP on Android 12

[mdev88]

Platform

Android 12

Plugin

network_info_plus

Version

4.0.2

Flutter SDK

3.13.3

Steps to reproduce

1. Run the sample code in an Android 12 (physical) device
2. The IPv4 is incorrect, and WiFi BSSID, WiFi Broadcast and WiFi Gateway are null

In the connection details screen I see that my actual IP is 192.168.0.15:
