Isn't it:
append(String name, String value)
append(String name, Blob value, String filename)?

If so, then:
DartStringAdapter value =
DartUtilities::dartToStringWithNullCheck(Dart_GetNativeArgument(args, 2),
exception);
...
receiver->append(name, value);

 
         return;
     }
+
+fail:
+    Dart_ThrowException(exception);
+    ASSERT_NOT_REACHED();
+}

+void appendBlobCallback(Dart_NativeArguments args)

these files don't seem to follow the 80 char convention. but I can break them if
preferred.

[blois, 2013/07/08 23:09:30]

Blink does not abide by the 80 char rule.
