finalinherited
onSaved → FormFieldSetter<List<T?>>?
An optional method to call with the final value when the form is saved via FormState.save.
finalinherited
reorderable → bool
final
restorationId → String?
Restoration ID to save and restore the state of the form field.
finalinherited
runtimeType → Type
