ComboboxItem disabled property.

[Piero512]

Is your feature request related to a problem? Please describe.
I am in the process of creating a desktop app that has customizable options, and I wanted to show a greyed out combobox option that could not be selected, with an additional tooltip explaining why that item is not selectable.

Describe the solution you'd like
I would love that the ComboboxItem class be updated to carry a disabled/enabled property that would style the Text or any other widget of the Combobox item, so that item will tell the user that is not a selectable option, but it could be supported if circunstances change. Although that might not be in compliance with WinUI3 and stuff, so a similar class like CommandBarBuilderItem would be acceptable.

Describe alternatives you've considered
Trying to cancel the onTap on the Selected State and raising a dialog explaining why the option can't work. Displaying only the currently supported options.

In my specific case, I could just remove from the option selector, say, the use CUDA option if my code detects that there isn't an NVIDIA GPU installed.

Added ComboboxItem.enabled. If you set it to false, the tap method is not invoked.

To create a custom combobox item, you can extend the ComboboxItem and override the build method.

final MyItem extends ComboboxItem {

  ...

  @override
  Widget build(BuildContext context) {
    return Tooltip(
      message: .....,
      child: super.build(context),
    );
  }

}
