SliderSuperFormField class

Regular material Slider 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 slider.

Most fields are kept the same as in Slider so see there for documentation of specific properties.

SliderSuperFormField(
  name: "power",
  rules: [MaxValueRule(limit, "Cannot exceed the user limit")],
