int pack(fb.Builder fbBuilder) {
final int? nameOffset = name == null ? null
: fbBuilder.writeString(name!);
final int? channelsOffset = channels == null ? null
: fbBuilder.writeList(channels!.map((b) => b.pack(fbBuilder)).toList());
fbBuilder.startTable(2);
fbBuilder.addOffset(0, nameOffset);
fbBuilder.addOffset(1, channelsOffset);
return fbBuilder.endTable();
