Bug summary

Working on an app where exceptions are occasionally reported when calling the this API. What's logged is that a null check was used on a null value on the following lines

https://github.com/adobe/aepsdk_flutter/blob/e385131d4f26ee4774fd19fd64ccd35c39fc1053/plugins/flutter_aepcore/lib/flutter_aepidentity.dart#L76 https://github.com/adobe/aepsdk_flutter/blob/e385131d4f26ee4774fd19fd64ccd35c39fc1053/plugins/flutter_aepcore/lib/flutter_aepidentity.dart#L43

This means the plugin itself expected a non-nullable values. Don't have steps to reproduce as tracing through the source code of the plugin shows that it does not check the error object on the iOS side and assumes calling the native iOS SDK works https://github.com/adobe/aepsdk_flutter/blob/e385131d4f26ee4774fd19fd64ccd35c39fc1053/plugins/flutter_aepcore/ios/Classes/FlutterAEPIdentityPlugin.m#L93. This effectively means the plugin is swallowing any errors being reported on the native and makes it difficult to know what went wrong. The following is an example of dealing with a NSError object on the iOS side can be done https://github.com/flutter/packages/blob/aa741d164ccd24aaaaee5fe4b4c1dcf9df931799/packages/camera/camera_avfoundation/ios/camera_avfoundation/Sources/camera_avfoundation/CameraPlugin.m#L19. This would allow the plugin to throw a PlatformException on Dart/Flutter side that apps can catch and get more detailed information on what went wrong. Note the docs for AEP also refer to catching a PlatformException (e.g. here), however it's not possible on iOS with how the plugin hasn't properly handled errors. This is in turn means it's not possible to see the AEPError code
