How to have different text overflow style in DropdownButton in hint text and in the DropdownMenuItem in Flutter?

Question

I want to set the overflow of hint text of DropdownButton to ellipsis, but I want to show the whole choice in the DropdownMenuItem when I open the dropdown list, so I set it to visible But what happens is that the hint text gets the "visible" effect despite that I set it to ellipsis, How can I fix this?
