please help if u can ..

edit: listview height isnt fixed, it may has 1 children or may 10 children

Answer 1

Wrap the ListView in a container.

You can wrap your ListView in a Container widget and set a fixed height:

 Widget build(context) {
        return Container(
          height: 100px //here you set desired height
          ListView.builder(
            shrinkWrap: true,
            itemCount: issues.length,
            itemBuilder: (context, int currentIndex) {
                return Stack(
                    children: <Widget>[
                        Container(
                            width:double.infinity,
                            color: Colors.grey[50],
                            child: createViewItem(issues[currentIndex], context)
                        )
                    ],
                );
            },
        ),
      );
    }

Answer 2

This happens because you wraped Expanded around your ListView. If you remove the Expanded your ListView will only take the necessary space.

Column(
                mainAxisSize: MainAxisSize.min,
                mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                children: [
                   Container(
                      // .... codes
                    ),
                    _getExpanded(),
                    Container(
                        child:Column(
                            children: [
                                Text("Address"),
                            ],
                        )
                    ),

                ],
            ),
