I usually use DropdownMenu as my go-to widget when I need a TextField with a dropdown where I can search for items. I use it in a form where there is at least one other form field (usually TextFormField) coming after it. It would be such a nice feature for DropdownMenu to have a textInputAction property so we can use something like TextInputAction.next to go to the next form field. Right now, it can only be TextInputAction.done (as a default value for the internal TextField it uses) which is not really helpful.
