In my Flutter project, I was using scan: 1.6.0 plugin for scanning barcodes/qr codes, which was working fine.
Recently I wanted to change the plugin to google_mlkit_barcode_scanning: 0.12.0, in android it works, fine, but when I try to use this in iOS, the scan is successful, but after 30-40 seconds, it throws an exception, due to which my app fails to respond
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString objectForKey:]: unrecognized selector sent to instance 0x3008ec410'
*** First throw call stack:

libc++abi: terminating due to uncaught exception of type NSException
I tried to create a demo project, and it worked fine in that project.
Any suggestion, what am I doing wrong here?
