RadioSuperFormField<T> class

Base class for creating radio groups that extends SuperFormField.

This widget's state automatically registers field for name so there is no need for manual registration.

Specify rules to add validation for this field. Errors will not be displayed automatically. Consider putting SuperFormErrorText below the field.

The field will automatically clear group value it no longer have corresponding option.

RadioSuperFormField.listTile(
  name: "size",
  options: const [
    RadioOption("s", Text("Small")),
    RadioOption("m", Text("Medium")),
    RadioOption("l", Text("Large")),
    RadioOption("xl", Text("X-Large")),
  ],
  rules: [RequiredRule("Please choose size")],
  dense: true,
),

Constructors

RadioSuperFormField({Key? key, required RadioBuilder<T> builder, required String name, required List<RadioOption<T>> options, List<SuperFormFieldRule>? rules, void onChanged(T? value)?, bool? enabled})
Creates a RadioSuperFormField that delegates its build to a builder while providing helpful RadioState abstraction.
RadioSuperFormField.listTile({Key? key, required String name, required List<RadioOption<T>> options, List<SuperFormFieldRule>? rules, bool toggleable = false, Color? activeColor, Widget subtitle(RadioOption<T> option)?, bool isThreeLine = false, bool? dense, Widget? secondary, bool selected(RadioOption<T> option)?, ListTileControlAffinity controlAffinity = ListTileControlAffinity.platform, bool autofocus = false, EdgeInsetsGeometry? contentPadding, ShapeBorder? shape, Color? tileColor, Color? selectedTileColor, void onChanged(T? value)?, bool? enabled})
Creates a Column of connected RadioListTiles which represent the options.
