EasyFormFieldController<T> class

Base controller class for use with custom form fields.

It can be used as an ancestor for a controller of a specific type, or directly without creating a descendant:

EasyCustomFormField<Color, EasyFormFieldController<Color>>(
  name: 'color',
  initialValue: Colors.teal,
  controllerBuilder: (value) => EasyFormFieldController<Color>(value),
  builder: (fieldState, onChangedHandler) => ColorField(
    controller: fieldState.controller,
    onChange: onChangedHandler,
  ),
)
