[Bug]: (share_plus) unable to share files on Android in release-mode only

[ViscousPot]

Platform

Android 15

Plugin

share_plus

Version

11.0.0

Flutter SDK

3.7.0

Steps to reproduce

Simply trying to share a file on Android in release mode. Works totally fine in dev, but shows the error in the provided logs in release mode. I could not get any logs in flutter specifically, but only in logcat, filtered to my app

Code Sample

final txtFiles = <XFile>[];
for (final f in files) {
  txtFiles.add(XFile(f.path, mimeType: 'text/plain'));
}

final result = await SharePlus.instance.share(ShareParams(files: txtFiles));
print(result);

Same on iPhones.

Any fix?

[ViscousPot]

Personally switched to flutter_mailer and am copying the contents of the file into an email, but I understand that is quite different.

No clue what the root cause for this issue is sadly..

We were obfuscating the build in release-mode.
So, the below solution worked for me.
