parseBundle function

ReturnResults<Resource> parseBundle(Bundle bundle)

Extracts all Resources that were returned by the Bundle, as long as they aren't OperationOutcomes, and includes all entries as informational OperationOutcomes that don't contain a Resource

Implementation

ReturnResults<Resource> parseBundle(Bundle bundle) {
  final ReturnResults<Resource> returnResults = ReturnResults<Resource>();

            returnResults.informationOperationOutcomes
                .add(entry.resource! as OperationOutcome);

                .add(entry.resource! as OperationOutcome);
