scanNetworks() throwing PlatformException on Android 11 Samsung A52

[aschaepper]

Hello together

This could be related to this: #10 but I'm not sure and im getting a different type of exception, a "PlatformException".

I dig a bit deeper and found that it the error most probably comes from WifiManager.StartScan()
https://developer.android.com/reference/android/net/wifi/WifiManager#startScan()
Location in Code:
https://github.com/weplenish/flutter-plugins/blob/master/wifi_flutter/android/src/main/kotlin/com/weplenish/wifi_flutter/WifiFlutterPlugin.kt#L59

First I thought its because of the deprecation of this method and its not possible at all but I also use this Flutter library:
https://github.com/weplenish/flutter_wifi_connect
https://pub.dev/packages/flutter_wifi_connect

And the code here which also uses StartScan from WifiManager works (From the flutter library: FlutterWifiConnect.connectByPrefix)
https://github.com/weplenish/flutter_wifi_connect/blob/main/android/src/main/kotlin/com/weplenish/flutter_wifi_connect/FlutterWifiConnectPlugin.kt#L217

To me it looks very similar (just read through it in github, I couldn't debug it directly). So I'm not sure where the error is (I cant imagine its from the suppressed lints and deprecation messages?). Maybe for you this is a bit easier to spot?

I'm using Android 11 on a Samsung A52 here it doesnt work.
On a Huawai P9 with Android 7 it works.

Maybe this helps you to find this or even the other errors?

Unfortunately I can't fix it myself at the moment, I'm freelancing and encountered this problem in a project for the customer, we have kind of a tight budget and schedule so I will weasel around the problem instead of fixing it.
