Allow the file picker to show only custom file extension

[sschuberth]

It seems like currently there's no way to only display files matching custom extensions in the picker. In my case, I'd like only *.json and *.yml files to show up for picking. Is this a functionality that could be added?

For now only custom mime types are supported, but I will add custom extensions in the future.
You can use:

FilePickerFileType.Custom(
    listOf(
        "application/json",
        "application/x-yaml",
    ),
),

"application/x-yaml"

Thanks, but I guess this will also allow to select *.yaml whereas I really only want *.yml, correct?

Yes, you can search for a specific mime type for that extension. I will try to add extensions support ASAP.
