All system mouse cursors from Win32 have been included except for one, IDC_UPARROW, whose description goes "a vertical arrow".

The reason it is not included is naming. Flutter's system mouse cursors follow a naming convention based on the cursors's usage instead of appearance, which deems verticalArrow inappropriate. However this cursor is so rare that I'm not aware of any use cases.

If you find this cursor necessary, comment below with a use case (or better, a name) and we can discuss adding this cursor.
