fieldPath property
The field path contains the field IDs and indices (for repeated fields) that lead to the proto member corresponding to a piece of generated code. Repeated fields in the descriptor are further identified by the index of the message in question. For more information see https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/descriptor.proto#L728
Implementation
List<int>? get fieldPath;
