Thanks for reporting the issue. Can you add some error logs, please?

Currently, V1.0.0 has been released, can you try it on the latest version?

instead of showing dialog in plugin side it would be nice to throw error so developers can catch it.

The errors are managed in the native part for both android and ios as the scanning is done in the native part. Currently, there is no functionality to get the error from the native to the flutter app as the required permissions/ error handling is already done at the native code.
