[Request]: Improve documentation for filename used in shareXFiles

[frieder-audriga]

Plugin

share_plus

Use case

When sharing a file that is created from data, like so

      var data = utf8.encode('Hello World');
      var fileName = 'myFile.txt';
      var mimeType = 'text/plain';
      var xFile = XFile.fromData(data, name: fileName, mimeType: mimeType);
      Share.shareXFiles([xFile]);

expected behavior would be that a file called "myFile.txt" would be shared. Instead "{randomUUID}.txt" gets shared.

This is caused by cross_file ignoring the name parameter, when creating an xFile via the fromData constructor see cross_file/lib/src/types/io.dart:43

This then causes share_plus to assign a name based on a random UUIDv6 and the mimetype.

Proposal

Ideally a convenient way (for example an optional parameter) would be introduced that allows us to set/ override the filename of a given file to share.

But if that is not wanted for some reason at least please add to the documentation that

• A random filename is assigned to files that have no filename set
• A note that XFile.fromData ignores the the filename
  • I am aware that cross_file is a separate project, but at least when navigating the API docs it is not possible to find this information.
  • For example https://pub.dev/documentation/share_plus/latest/share_plus/XFile/XFile.fromData.html lists no such note.
