In this answer, I used to suggest using the NetworkInterface in 'dart:io', however NetworkInterface.list is not supported in Android (as pointed out by Mahesh). The wifi package provides that, but later this was incorporated to the flutter's connectivity plugin. In Oct/2020 the methods for that were moved from the connectivity to the wifi_info_flutter plugin.

So just go for wifi_info_flutter and call await WifiFlutter().getWifiIP().

By the way, you may also want to check if Wifi is available using the connectivity plugin in flutter/plugins. Here's an example of how to check if wifi is available.
