final List<Map<String, dynamic>> _items = [
{
'value': 'boxValue',
'label': 'Box Label',
'icon': Icon(Icons.stop),
},
{
'value': 'circleValue',
'label': 'Circle Label',
'icon': Icon(Icons.fiber_manual_record),
'textStyle': TextStyle(color: Colors.red),
},
{
'value': 'starValue',
'label': 'Star Label',
'enable': false,
'icon': Icon(Icons.grade),
},
];
SelectFormField(
initialValue: 'circle',
icon: Icon(Icons.format_shapes),
labelText: 'Shape',
items: _items,
onChanged: (val) => print(val),
onSaved: (val) => print(val),
);
The result of val in onChanged, validator and onSaved will be a String.
