 The compiler is broken.
 
 When compiling the above element, the compiler crashed. It is not
 possible to tell if this is caused by a problem in your program or
 not. Regardless, the compiler should not crash.
 
 The Dart team would greatly appreciate if you would take a moment to
 report this problem at http://dartbug.com/new.
