You can use icon param

PopupMenuButton(
          icon: Icon(Icons.more_vert,color: Colors.white), // add this line
          itemBuilder: (_) =>  ......,
          onSelected:....
)

Hope this will work for you.

Theme(

      iconTheme: IconTheme.of(context).copyWith(
    color: Colors.amber,
  )),
  child: PopupMenuButton(
