+// Generated by dart2js, the Dart to JavaScript compiler version: 1.10.0-edge.45075.
 // The code supports the following hooks:
 // dartPrint(message):
 //    if this function is defined it is called instead of the Dart [print]
 //    method.
 //
 // dartMainRunner(main, args):
 //    if this function is defined, the Dart [main] method will not be invoked
 //    directly. Instead, a closure that will invoke [main], and its arguments
 //    [args] is passed to [dartMainRunner].
