-// Generated by dart2js, the Dart to JavaScript compiler.
-// The code supports the following hooks:
-// dartPrint(message)   - if this function is defined it is called
-//                        instead of the Dart [print] method.
-// dartMainRunner(main) - if this function is defined, the Dart [main]
-//                        method will not be invoked directly.
-//                        Instead, a closure that will invoke [main] is
-//                        passed to [dartMainRunner].
