How to add animation to “DropdownButtonFormField” (Flutter)

Question

How to add animation to DropdownButtonFormField in Flutter?

I want to animate the button when it is clicked and open the list of DropdownMenuItem .

So, how can I do that? Is it possible?

Answer 1

The base widget doesn't let you customize its animation. To do this you could recode a DropdownButtonFormField widget by looking through the original source code and adding your animation wherever you want.
