[file_selector_windows] Save file dialog does not populate with initial filename and filter(s).

[andrewmk]

Creating a 'file save' dialog on Windows using the file_selector_windows plugin doesn't populate the filename part of the dialog with the suggested filename and doesn't populate anything into the filters drop down (it's empty). This happens in my custom app but also in the example app provided at https://github.com/google/flutter-desktop-embedding/tree/master/plugins/file_selector/example as at commit 7daa15e90672542f730ec871b1a6e84a5b7b8f3c. I see a similar sounding issue #842 with file_selector_macos was closed recently with the comment that the problem was not with file_selector_macos. If this current problem is not with file_selector_windows I'd be happy to try to diagnose where the problem is if someone could give me some pointers.

Creating a 'file save' dialog on Windows using the file_selector_windows plugin doesn't populate the filename part of the dialog with the suggested filename and doesn't populate anything into the filters drop down (it's empty).

I'm not able to reproduce this; please provide your Dart code.

This happens in my custom app but also in the example app provided at https://github.com/google/flutter-desktop-embedding/tree/master/plugins/file_selector/example as at commit 7daa15e.

You've shown a screenshot of a dialog in the example that doesn't pass a filename (which is a bug in the example) or filter, so those images are the expected result of the code in the example.

I see a similar sounding issue #842 with file_selector_macos was closed recently with the comment that the problem was not with file_selector_macos

That was an issue with the use of cross_file and had nothing to do with the dialogs, so I'm not sure what similarity you're referring to.

Thank you. With your fixed example I was able to see what I wasn't understanding about the API and what to change to make my app work properly.
