[Question] How to use the plugin effectively?

[surister]

Hello, I have a few question that I hoping someone can help me with.
flutter doctor

./flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 1.22.5, on Linux, locale en_US.UTF-8)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
[!] Android Studio (version 4.0)
    ✗ Flutter plugin not installed; this adds Flutter specific functionality.

Testing device: Samsung galaxy a70 (android 10) latest.

I am trying to use this library and I am not quite sure if I am using it effectively.

Questions:

1. Can you connect to a normal wifi?

I have tried to connect it to my home wifi and yielded this results:

FlutterWifiConnect.connectToSecureNetwork(ssid, password: WPA2)
It always connects (regardless if the password is correct or not) but always without internet connection.

FlutterWifiConnect.connect(ssid) (Having open my wifi):
It always connects but without internet connection.

2. If it is only for IOT devices, can you communicate with them via Sockets?

If I connect to a device that generates their own wifi (wifi is always without internet obviously) can I communicate with it using sockets?

I can manually connect to its wifi and talk to it using TCP sockets,
does the connection made by this plugin holds the same behaviour in order to automatize the wifi connection process?

Thank you very much in advance.
