.save() will not write to file if file is larger than bytes provided

[deathblade666]

Before creating an issue, make sure that you are on the latest file_picker version and that there aren't already any similar opened inssues. Also, check if it isn't described on the Wiki, specially on Troubleshooting page.

Also, sometimes a simple flutter clean and flutter build again with latest file_picker version, may end up by fixing cached issues, so I encourage you to first do so.

Describe the bug using the bytes flag, when trying to update an existing file, it will not write to the file if the file size is more than the bytes you are trying to write (i.e. if content was removed from the file).

How are you picking?

List<int> list = utf8.encode(OpenFile.text);
            Uint8List bytes = Uint8List.fromList(list);
            await FilePicker.platform.saveFile(bytes: bytes);

The plugin is intended to use an integral copy of the original file and not ever modify the original file itself.
