// Windows share behavior note:
// The Windows Share contract requires a primary share format (Text/Uri/Image)
// to be present before it accepts file attachments. If we pass only a file,
// the Share UI may not open or may fail silently. Adding even a dummy text
// ensures Windows recognizes the share content and then includes the file
// as an attachment. This is a Windows API requirement, not a share_plus bug.

In my case this works and i got this after doing a lot of attempt. So go for it and let us know it works for you too.
this small text is required for the share sheet to open in windows and normalized path is necessary for the windows to load your files or images.

please look into the image to see how to form normalized path, because in written a backslash is missing, no matter what i do.

final normalizedPath = fullPath.replaceAll('/', '\');
await SharePlus.instance.share(
ShareParams(
text: 'PDF downloaded successfully.',
files: [XFile(normalizedPath)],
sharePositionOrigin: const Rect.fromLTRB(820, 100, 10, 0),
),
);

I encountered the same problem on Windows. I managed to fix it by setting the text parameter in ShareParams.

Hi, I encountered the same issue and fixed it by using path normalization. It is working fine on my system but on my teammate's system it is showing same error. May I know are there any windows version contraints for this

[MSOB7YY]

if any one looking for a temporary solution, i made a fork with the latest working windows version (v10.1.4) but with updated win32 and kotlin versions, so it should be compatible with other new packages
fork is diverted from 66487533cecb0be5a2aaadbc08da4144fb60c993 which is the latest commit before refactoring SharePlus

use like this

  share_plus:
    git:
      url: https://github.com/MSOB7YY/plus_plugins
      ref: working_windows
      path: packages/share_plus/share_plus
