File Not Saving to Download folder in MI 9i

I'm trying to save the pdf file in the downloads folder, DocumentFileSavePlus.saveFile(pdfBytes, filename,"appliation/pdf") runs successfully without error, but the file is not saved, this issue is only happening in MI phone.

It is Working flawlessly in pixel emulators and Samsung phones including android 13.

Upgrade to Null Safety

Hi :)

Thank you for providing this package! You suceeded, where others did not: I had a lot of trouble writing data files (json) to the download dir on some Android versions. With your package it's working like a charm!

I've just opened a Pull request, that contains the migration to null safety.

I would be super happy, if you would publish a new version. This is the last dependency, I need to update, in order to migrate my project to sound null safety ;)

Thank you!

Kind regards,
Anne
