Чтение конфигурации управляемого приложения во Flutter Android

Я смог понять это. В MainActivity.kt:

class MainActivity: FlutterActivity() {
    private val CHANNEL = "com.yourstuff.whatever/something"

   override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
    super.configureFlutterEngine(flutterEngine)
    MethodChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setMethodCallHandler {
      call, result ->
      var myRestrictionsMgr =
        activity?.getSystemService(Context.RESTRICTIONS_SERVICE) as RestrictionsManager
        var appRestrictions: Bundle = myRestrictionsMgr.applicationRestrictions
    
       result.success(appRestrictions.getString(call.method))
    }
  }
}

И в трепете назвать это:

const platform = const MethodChannel("com.yourstuff.whatever/something"); 
platform.invokeMethod("restrictionname");
