Hello @klydra ,

I found ur package very useful, but I want to know whether there is any options/feature that I can listen to a particular SSID to get the live updates ?

After running the example app that you have provided, sometimes the app shows negative timestamp values. The timestamp value which is the microseconds passed after the device reboot shouldn't be negative and I suspect its happening because of int overflow. (timestamp is being cast to Int, shouldn't it be long?)

This is exactly what we need 👍
Any chances you port it for iOs?

I just clone this repo and build.
It just give me the error below

I get this error while building:

.pub-cache/hosted/pub.dartlang.org/wifi_hunter-1.1.0/android/src/main/java/klydra/wifi_hunter/WiFiHunterPlugin.java uses or overrides a deprecated API.

I am using package example and i'm taking this issue ;

PlatformException(2, WiFi Scan failed. Most likely your app is being throttled. Check out https://developer.android.com/guide/topics/connectivity/wifi-scan#wifi-scan-throttling for more information., null, null)

How can i solve this?

Is there any change iOS support will get built in?

Hi,
I am Federico and I'm using this Flutter libraty to get the list of APs from my phone, but I can't see any info. I implemented my code in a very similar way as the example code, but with no success.
Can you give me more details on how to get AP list in the proper way?
Thank you.

It's possible to get the Wifi channel?

Thanks;
