it looks like you can add length directly here:
int len = strlen(str);
DCHECK_LT(len, 256);
record += static_cast<char>(len);

Sure. This strange code appeared because of double rewriting parts of it :)

+  record += str;
+  int len = strlen(str);
+  DCHECK_LT(len, 256);
+  record[length_ptr] = static_cast<char>(len);  // Set length byte.
+}
+
+const std::string& DnsTxtBuilder::Build() const {
+  return record;
+}
