writeTag method
      
  
void
writeTag(})
       
    
override
    Writes a NbtTag from fileReader.
If the parent is a NbtList or NbtArray, withName should be set to false to avoid writing
any names of this Tag.
Implementation
@override
void writeTag(NbtWriter nbtWriter,
    {bool withName = true, bool withType = true}) {
  if (withType) nbtWriter.writeByte(nbtTagType.index);
  if (withName) {
    nbtWriter.writeString(name);
  }
  nbtWriter.writeInt(children.length, signed: true);
  for (final val in children) {
    nbtWriter.writeInt(val, signed: true);
  }
}
