# Fields

Field types form the backbone of [Addons](/addons/overview) and [Args](/args/overview) in Widgetbook. These types define the
data that can be manipulated within the Widgetbook environment, enabling users to tweak
settings and see their impact in real-time. Each field type corresponds to a different
data input and is represented by a suitable user interface element.

| `StringField`            | `String`      | `TextField`                                            |
| `DurationField`          | `Duration`    | `TextField`                                            |
| `DateTimeField`          | `DateTime`    | `TextField` (with `showDatePicker` & `showTimePicker`) |
| `ColorField`             | `Color`       | `ColorPicker`                                          |
| `IterableSegmentedField` | `Iterable<T>` | `SegmentedButton<T>`                                   |
| `ObjectDropdownField`    | `T`           | `DropdownMenu<T>`                                      |
| `ObjectSegmentedField`   | `T`           | `SegmentedButton<T>`                                   |

Each field type makes Widgetbook a flexible and powerful tool for Flutter developers. They
allow for real-time changes and visualization of various widget properties, thus enabling
interactive development and testing.
