Resizing not working in DropDownMenuItem

[jabirmayar]

It is not working on DropDownButton Children i.e DropDownmenuItem, I tried wrapping AutoTextsize within a Expanded Widget and Fittedbox but still no use. Example Code:
new DropdownMenuItem( child: Expanded(child: new AutoSizeText('Portuguese', style: TextStyle(color: parseColor("#dadce0"),fontSize: 15), minFontSize: 10, maxFontSize: 18, maxLines: 4, overflow: TextOverflow.ellipsis, )), value: 'pt', ),
