Hello, I have no idea, honestly, but a couple of things to consider nevertheless:

1. Avoid using XFile.fromData and instead write down the file in a folder you control. This shold be mentioned in the README.md file. The name parameter in XFile does nothing, only works on web, this is a known issue in the XFile dart package.
2. shareXFile() doesn't work at all on Linux. Also mentioned on the README file. Saying this because you have || Platform.isLinux in the example code.
