Constructors

InputRadio({Key key, bool autovalidate: false, Color activeColor, Color color, InputDecoration decoration, Axis direction: Axis.vertical, bool enabled, T initialValue, List<DropdownMenuItem<T>> items, Map<String, dynamic> map, ValueChanged<T> onChanged, ValueSetter<T> onSaved, String path, List<InputValidator> validators, bool wantKeepAlive: false})

Properties

activeColor → Color
final
autosave → bool
Automatically saves a changed value. If autovalidate is true then a changed value will only be saved if there is no validation failure. Also invokes method onSaved. Default is true.

final, inherited
onChanged → ValueSetter<T>
An optional method to call on every change of the fields value.
final, inherited
onSaved → ValueSetter<T>
An optional method to call with the final value when the form is saved through InputFormState.save().
final, inherited
path → String
The path to the fields value in map. If the form is nested then path elements must be dot separated.
