| // 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. |
