Easy way of changing the style of the selected item's text about dropdown_button2

[Apollo108]

I'm just wondering, why selectedItemBuilder always returns a List<Widget>, including the case, where there is only one selected item? What should I do in this case?

Thank you anyway)

What's the problem with selectedItemBuilder ?
It's familiar and been used at flutter's DropdownButton.

The only problem with it - it's not user friendly for this simple case. Any chances of adding the selectedItemTextStyle (or something similar) property soon? Or maybe to make it a part of the buttonStyleData... Thanks.

The thing is: making selectedItemTextStyle will not just update TextStyle of the items but will also ignore the other characteristics applied to items like padding, alignment, etc.. so, you'll have to use selectedItemBuilder anyway.

[AhmedLSayed9]

If you don't want to duplicate items.map(...).toList() part at both items and selectedItemBuilder properties, you can make a helper function that take your TextStyle as a parameter and return that list:

items: getItemsList(textStyle: TextStyle(...)),
selectedItemBuilder: getItemsList(textStyle: TextStyle(...)),

There's no way to do that internally at the package.

It allows more flexibility in specifying how a certain selected item is displayed, same as items, i.e:

selectedItemBuilder: (BuildContext context) {
  return items.map<Widget>((String item) {
    if (item == "something")
      return Text(
        item,
        style: TextStyle(color: Colors.red),
      );
    return Text(item);
  }).toList();
},

That'll show text in red only when something item is selected.

If you don't care and want to show the same for all items then just return the same widget :)
