I would prefer if this was an internal error:

if (compiler.enqueuer.resolution.getCachedElements(element) === null) {
  compiler.internalError('Unresolved element: $element', node: node);
}

Done.

     FunctionElement functionElement = element;
     element = functionElement.defaultImplementation;
     HInstruction target = new HStatic(element);
