The path returned by FilePicker.platform.saveFile does not exist on ios

[kjxbyz]

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.
