『dart2js.bat』による自動生成なので、こんなに長い!
普通に書いたら、ここまで長くならない!
(というか、これは、ありえないほど長くなっている!)

もちろんコード修正は、Dartコードを触ればいい!

// Generated by dart2js, the Dart to JavaScript compiler version: 1.21.0. 
// 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]. 
// 
// dartDeferredLibraryLoader(uri, successCallback, errorCallback): 
//    if this function is defined, it will be called when a deferred library 
//    is loaded. It should load and eval the javascript of `uri`, and call 
//    successCallback. If it fails to do so, it should call errorCallback with 
//    an error. 
// 
// defaultPackagesBase: 
//    Override the location where `package:` uris are resolved from. By default 
//    they are resolved under "packages/" from the current window location.
