Hello, thank you for your interest in the project.
In the initial version of the plugin, the tag contents were stored in memory, and the tag contents were recorded when the app was closed and restarted.
However, due to a request to record tag contents in permanent storage and read the tag contents from a file when the app starts, this feature has been applied to the currently published plugin.
After testing again, we found that if there is no file initially, a message is displayed as an exception. This issue does not affect the normal operation of NFC HCE.
I will work to improve this in future updates.
Thank you once again. Have a great day and good luck!
