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.

Anybody else facing this issue?

Yes, of course! I have same problem with file picking from android file manager. I install pub file_picker: ^6.1.1 and try
FilePicker.platform.pickFiles(allowMultiple: true).then((value) =>
value != null
? _onFilesRecieve(value.files.map((e) => File(e.path!)).toList())
: null);
and on Android 14 (and some Android 13 shells), the result of the value always is "null"
I have set the values for compileSdkVersion 34 and targetSdkVersion 34 and it didn't have any effect.

Here is my flutter doctor -v results:
