Allow setting the start/opening offset of DropdownMenuItem

Is there an existing issue for this?

• I have searched the existing issues

Use case

DropdownButton should have the possibility to open below itself. At the moment this is not an option.
See your own example: https://api.flutter.dev/flutter/material/DropdownButton-class.html
In there the dropdownbutton opens above the button itself.

Proposal

PopupMenuButton has the possibility to change the starting offset. By changing the offset to 40 the PopupMenuButton opens below itself:
PopupMenuButton( offset: const Offset(0, 40),

Please can you add this to DropdownButton as well? And thuse allow Dropdownbutton to open below itself.

It seems that Dropdownbutton2 from pub.dev does open as desired just below the dropdownbutton2 itself. However that is not a flutter package and thus I prefer not to use it in production apps.

Hi @bochelie1000. This seems to be about DropdownButton being customizable in which there is a currently open issue #25151, you can upvote and comment on the existing issue. Kindly confirm this suits your case as well.

My question is for a different option however, it is a customization. If it is better to add it to that question than lets do it.
