• textStyle: [TextStyle | null],
• label: [String | null],
• icon: [Widget | null],
• enable: [bool | null],

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(
  type: SelectFormFieldType.dropdown, // or can be dialog
  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.
So, if you tap on Box Label item on select menu the result will be boxValue.
