Accessing native plugin from TaskHandler

[insidewhy]

Hi,

I want to access the Wi-Fi SSID, BSSID and RSSI from my TaskHandler so I can measure how the wifi strength varies over time. In the onEvent method of my TaskHandler I'm calling WifiInfoAndroid.getWifiInfo which is from the wifi_info_android plugin. The code for that is pretty simple, it can be found here: https://github.com/sol-x/wifi_info_android/blob/main/android/src/main/kotlin/co/solx/wifi_info_android/WifiInfoAndroidPlugin.kt

When trying to access the wifi info from the TaskHandler I always get a null value though. I'm not sure if there is a general issue with calling native code via a MethodChannel from a TaskHandler or if it's something specific to do with activity aware plugins.

Maybe I should be accessing the wifi info from receivePort.listen and only using the sendPort in the TaskHandler to indicate that the main thread should be accessing the wifi info?

When your app is in the background, it doesn't have an Activity object. The plugin you introduced is implemented so that null is always returned if there is no Activity object. - Line45

Try implementing it using flutterPluginBinding.applicationContext in onAttachedToEngine function instead of binding.activity.
