import 'package:flutter/material.dart'; import 'package:flutter/widgets.dart'; import 'dart:ui';  void main(){     runapp(new branchsetup());       }  class branchsetup extends statefulwidget {     @override     state<statefulwidget> createstate() {          return new _branchsetupstate();           }        }       class _branchsetupstate extends state<branchsetup>                                  widgetsbindingobserver {       @override            widget build(buildcontext context){            return new materialapp(               theme: new themedata(                   primarycolor: const color(0xff229e9c),                                 ),               title: 'branch setup',               home: new scaffold(               body: new container(               child: new listview(                 children: <widget>[                  new container(                    margin: const edgeinsets.all(16.0),                     child: new row(                      children: <widget>[                       new expanded(                         child: new textformfield(             decoration: new inputdecoration([enter image description here][1]                                                   labeltext: 'branch name',                    ),                 ),               ),             ],           ),          ),           new container(             margin: const edgeinsets.all(16.0),             child:               new dropdownbutton<string>(                 items: <string>['mens','womans']                       .map((string value) {                     return new dropdownmenuitem<string>(                         value: value,                         child: new text(value),                     );                   }                   ).tolist(),                onchanged: null,                 ),             ),            ],         ),         ),      ),     );    }    }

this looks bug in flutter. filed issue.

in meantime, can work around wrapping dropdownbutton in column.

import 'package:flutter/material.dart';  void main() {   runapp(new materialapp(home: new demoapp())); }  class demoapp extends statelesswidget {   @override   widget build(buildcontext context) {     return new scaffold(       appbar: new appbar(title: new text('dropdownbutton example')),       body: new listview(         children: [           new column(             children: <widget>[               new dropdownbutton<string>(                 items: <string>['foo', 'bar'].map((string value) {                   return new dropdownmenuitem<string>(                     value: value,                     child: new text(value),                   );                 }).tolist(),                 onchanged: (_) {},               ),             ],           ),         ],       ),     );   } }
