# Fields

Field types form the backbone of Addons and Knobs 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.

| ------------------------ | ------------- | ------------------------------------------------------ |
| `BooleanField`           | `bool`        | `Switch`                                               |

| `IntSliderField`         | `int`         | `Slider`                                               |

| `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.
