i'm facing issue to share pdf file on windows,
getting "ShareResultStatus.unavailable" error

[miquelbeltran]

ShareResultStatus.unavailable is not an error, that just indicates that the share result is unknown.

I'd advise checking with v11 of the plugin, as the implementation was refactored.

[selvam920]

after update to latest version, unable to share file on windows 11, previously it was working,
then how to share file on windows 11?

[selvam920]

is this bug or issue from my side?

[TheLastFlame]

I've encountered this problem before (#3197)

For some reason share_plus is not able to work with xFile just like that. It needs to be saved in a clear path so that share_plus can access it. Otherwise it tries to send something that doesn't exist.

I'm not sure if this requires an update to the documentation, or still some sort of solution to this problem on the share_plus side.

This is the code that gets around the problem:

var temp = (await getTemporaryDirectory()).path;
final filePath = path.join(temp, name);
var file = File(filePath);
await file.writeAsBytes(bytes);

await SharePlus.instance.share(
    ShareParams(files: [XFile(filePath)]),
);

[TheLastFlame]

@miquelbeltran, last time you answered similarly about ShareResultStatus.unavailable, however we are not interested in getting the share status, but just to share the file. And it doesn't work, without the manipulation above not being obvious.
This looks like a bug that needs to be either fixed or at least explained in the documentation.

[miquelbeltran]

It needs to be saved in a clear path so that share_plus can access it. Otherwise it tries to send something that doesn't exist.

Ah, thanks, that's probably why I didn't see the problem when I did my tests.

To help me understand this problem better, what would be an example of a file path that fails and an example of a file path that works?

Copying the file into a temporal directory is what we already do internally when you use XFile.fromData, because the file.path would be empty.

plus_plugins/packages/share_plus/share_plus_platform_interface/lib/method_channel/method_channel_share.dart

Lines 81 to 89 in c8c1a14

	Future<XFile> _getFile(
	XFile file, {
	String? tempRoot,
	String? nameOverride,
	}) async {
	if (file.path.isNotEmpty) {
	return file;
	} else {
	tempRoot ??= (await getTemporaryDirectory()).path;

Maybe the solution is to simply always copy the file into the temporal directory, no matter if you provided a path or not.

last time you answered similarly about ShareResultStatus.unavailable, however we are not interested in getting the share status, but just to share the file.

The thing is that people get confused by the responses' status name, so I need to clarify every time that unavailable != bug or error.

i used
await SharePlus.instance.share(
ShareParams(
files: [
XFile(
AppConstants.isWindows()
? filePath.replaceAll("/", "\")
: filePath,
),
],
),
);
filepath is a windows temporary directory file, why it's not workng

[selvam920]

share some sample code to share file on windows

[TheLastFlame]

@selvam920, do you happen to have the temporary file deleted after the save is complete?

It's just that await on share on Windows doesn't work. Accordingly, functions after await are executed immediately, not waiting for the send process to complete.

Judging by your screenshots, share on Windows menu is trying to load a file that doesn't exist anymore.

[selvam920]

can you check it's simple example

[selvam920]

same thing is working with previous version 10.1.4
