JsonSchemaValidator class final

A compiled JSON Schema validator that validates Dart maps against a schema.

JsonSchemaValidator is a convenience wrapper around SchemaParser that accepts either a Map<String, dynamic> or a JSON string, compiles the schema at construction time, and exposes a single validate call.

This type is intended for consumers who need to validate documents against a JSON Schema without understanding the internal SchemaRule hierarchy.

Example:

final validator = JsonSchemaValidator.fromMap({
  'required': ['name', 'email'],
  'properties': {
    'name': {'type': 'string', 'minLength': 1},
    'email': {'type': 'string', 'format': 'email'},
  },
});

final violations = validator.validate({'name': 'Alice'});
// → [SchemaViolation(path: 'email', message: 'required field is missing')]
