constrainSchemaObject method Null safety

void constrainSchemaObject(
  1. APIDocumentContext context,
  2. APISchemaObject object
)

Adds constraints to an APISchemaObject imposed by this validator.

Used during documentation process. When creating custom validator subclasses, override this method to modify object for any constraints the validator imposes.

Implementation

void constrainSchemaObject(
    APIDocumentContext context, APISchemaObject object) {
  switch (type!) {
    case ValidateType.regex:
