Parameter initialDirectory of getDirectoryPath() not working on Windows

[julianklose]

Describe the bug
I'm using the newest version (4.4.0) of the file_picker including the new initialDirectory option. I tried using it with the directory picker. Unfortunately, it doesn't seem to work, I always start at my home directory.

Platform

• Android
• iOS
• Web
• Desktop

Platform OS version
Windows 10

How are you picking?

var dir = await FilePicker.platform.getDirectoryPath(
        lockParentWindow: true, initialDirectory: Directory.current.path);

I just read in #953, that it doesn't work with the windows directory picker. Maybe it will with #915. Can you add a notice about this in the documentation until it works?

Hi @julianklose , thank you for noticing this. The Dart docs will be fixed with #915 and I already updated the API section of our wiki.

Fortunately, Microsoft's IFileDialog API supports setting the initial directory even when picking a directory. However, I don't understand how to use it. So, setting the initial directory for the directory picker dialog is still not possible in file_picker. Sorry for the inconveniences.
I added a TODO to our code for the missing implementation and I'll close this issue until I or someone else finds out how to use the SetFolder() / SetDefaultFolder() methods.
