After integrating this plugin in our project, method channel of some other plugins can't be called from iOS to flutter, how to solve it? anyone knows?

When I comment out the following code in the method "startGeofencingService" of file "GeofencingPlugin.m", it works, but what will it cause?

if (!backgroundIsolateRun) { registerPlugins(_headlessRunner); }
