Drag/Dropping a file failing on Linux

[hobleyd]

Hi,

I have written some code to drag/drop files which works on MacOS but fails on Linux. The code which handles the drop is:

Future<void> onPerformDrop(PerformDropEvent event) async {
  if (event.session.items.isNotEmpty) {
    for (var item in event.session.items) {
      final reader = item.dataReader!;
      if (reader.canProvide(Formats.fileUri)) {
        reader.getValue(Formats.fileUri, (uri) async {
          if (uri != null) {
            Uri toFileUri = Uri.parse('${destination.uri}${basename(Uri.decodeComponent(uri.path))}');

            // do stuff with the dropped file.
            };
          }
        });
      }
    }
  }
}

On linux, the reader.getValue function appears to provide a null URI even though the supported formats indicate that text/uri-list is acceptable:

[text/plain;charset=utf-8, text/uri-list, application/vnd.portal.files, application/vnd.portal.filetransfer, application/x-gtk-local-dnd, text/plain]

An ideas what I am doing wrong please?

Cheers,
David
