PlatformException: WRITE_ERROR, Error whole finalizing destination for writing metadata

[Flajt]

Hello,

I've tried to add the following key: FileSource (lkCGImagePropertyExifFileSource) since there doesn't seem to be support for the Software Tag?

However, every time I try to save the code, it crashes on me with this error and creates an empty file.
I can't do much debugging without a real error message, since I've not worked with Swift so far.

Link to my file: here

Do you know by any chance why?
EDIT: The library version in pubspec.yaml is ^0.6.0

Could due to invalid data, since I passed a Text not a number / number string.
