// Generated by dart2js (, csp, intern-composite-values), the Dart to JavaScript compiler version: 3.9.2.
// 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, loadId, loadPriority):
//    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. The loadId argument is the deferred import that resulted in
//    this uri being loaded. The loadPriority argument is an arbitrary argument
//    string forwarded from the 'dart2js:load-priority' pragma option.
// dartDeferredLibraryMultiLoader(uris, successCallback, errorCallback, loadId, loadPriority):
//    if this function is defined, it will be called when a deferred library
//    is loaded. It should load and eval the javascript of every URI in `uris`,
//    and call successCallback. If it fails to do so, it should call
//    errorCallback with an error. The loadId argument is the deferred import
//    that resulted in this uri being loaded. The loadPriority argument is an
//    arbitrary argument string forwarded from the 'dart2js:load-priority'
//    pragma option.
//
// dartCallInstrumentation(id, qualifiedName):
//    if this function is defined, it will be called at each entry of a
//    method or constructor. Used only when compiling programs with
//    --experiment-call-instrumentation.
