When the FDateField is positioned at the bottom of the page, its popover is obscured by the on-screen keyboard.

Additionally, after the popover overlaps the FDateField, the field's cursor (caret) appears above the popover, causing a visual layering issue.

Good catch! I think the first one is a fairly straightfoward fix, second one is pretty complicated.

Seems like this is a known issue in Flutter, see flutter/flutter#13182.
