Hi there,

It is important to note that the dart:ffi package is not designed to be used with web-based Flutter applications, and attempting to use it may result in compilation errors or other issues.

If anyone has experience with the building dart:ffi package in Web to fix compile issues and might be able to offer some guidance, I would really appreciate it.

Thank you for your time and help.

Best regards, Khoren

r-ilagan commented 1 year ago

Is there a way to expose the library only when compiling for mobile?

khoren93 commented 1 year ago

@r-ilagan

I have released a new version v0.9.0 and would like to ask if you could please check if the issue still persists in the new version.

r-ilagan commented 1 year ago

Hi @khoren93 ,

I just tested out the new version and it works! Web is able to run perfectly. Thank you for the quick resolution! I also noticed a change in the onScan() parameter with CodeResult to Code. Perhaps it should be documented. Other than that, it's looking good on my end.

Thanks again!

khoren93 commented 1 year ago

I am closing this issue because it has been fixed in the latest version. Thanks for reporting the issue.
