validateStrict method

@override Object? validateStrict(Map<String, dynamic>? value, { bool returnAllErrors = false, bool returnAsList = false, })

Validates the object strictly, including type checks for each field.

Implementation

@override
Object? validateStrict(Map<String, dynamic>? value, {bool returnAllErrors = false, bool returnAsList = false}) {
  if (value == null) return invalidTypeMessage;

  List<String> errors = [];

  // Check for missing required fields
  for (var key in _schema.keys) {
    if (!_optionalFields.contains(key) && !value.containsKey(key)) {
      errors.add("$key is required");
    }
  }

  // Validate unexpected keys
  if (!_allowExtraKeys) {
    final extraKeys = value.keys.toSet().difference(_schema.keys.toSet());
    if (extraKeys.isNotEmpty) {
      errors.add("Unexpected keys found: ${extraKeys.join(', ')}");
    }
  }

  // Validate fields against their respective validators
  _validateSchemaStrict(value, errors, returnAllErrors, returnAsList);

  return returnAllErrors ? errors : (errors.isNotEmpty ? errors.first : null);
}
