copyWithNullable method

@override CheckboxGroupFieldState<T> copyWithNullable({ Set<T>? value, })

A null-tolerant version of copyWith, allowing you to explicitly set fields to null.

This is useful for form reset behaviors like clearing a field's value or removing its error.

Implementation

@override
CheckboxGroupFieldState<T> copyWithNullable({
  Set<T>? value,
}) {
  return CheckboxGroupFieldState<T>(
    checkboxes,
    value: value,
    error: error,
    label: label,
    rules: rules,
  );
}
