    initView: initView,
    appBaseURLChangedCallback: () {
      showToast("current: $kBaseURLType");
      1.delay(() {
        main();
      });
    },
    completionCallback: () {
      runApp(createApp());
      if (isAndroid) {
        SystemChrome.setPreferredOrientations([
          DeviceOrientation.portraitUp,
          DeviceOrientation.portraitDown,
        ]);
        // Set overlay style status bar. It must run after MyApp(), because MaterialApp may override it.
        SystemUiOverlayStyle systemUiOverlayStyle =
            SystemUiOverlayStyle(statusBarColor: Colors.transparent);
        SystemChrome.setSystemUIOverlayStyle(systemUiOverlayStyle);
