Library Crashing when running in iOS

[toniree]

Hi, I've hooked this library up to my Flutter iOS application, but trying to run the app on my iPhone is crashing with this message:

Launching lib/main.dart on iPhone 8 in debug mode...
Running Xcode build...
Xcode build done.                                           25.9s

Is the FlutterGeofencing library still supported with the latest Flutter versions? Or is the message above tied to common mistakes in implementing this library? The above pops up when trying to run on an iPhone emulator. When trying to run on a physical iPhone, the above message does not pop up, rather, the app launches and crashes immediately with no message or exception.

Things run fine when I run the app with FlutterGeofencing detached and not used, so I know it's the library that is causing the failures.
