How can we change the width/padding of a Flutter DropdownMenuItem in a Dropdown?
This feature has been added. See https://github.com/flutter/flutter/pull/14849 You can now wrap it in a ButtonTheme and set alignedDropdown to true. return Container( width: 300.0, child: DropdownButtonHideUnderline( child: ButtonTheme( alignedDropdown: true, child: DropdownButton( value: name, items: listOfDropdownMenuItems, onChanged: onChanged, style: Theme.of(context).textTheme.title, ), ), ), );
