  @override
  Widget build(BuildContext context) {

  }
}

this is my MyApp Class where want to call 2 builder

1. BotToastInit(),
2. EasyLoading.init() how i call both of this? builder: //here ,

Answer 1

The builder parameter must return one widget. If you like to do initialization or return two widgets, you've to nest them yourself inside the builder:

builder: (context, child) {
    // do your initialization here
    child = EasyLoading.init();  // assuming this is returning a widget
    child = botToastBuilder(context,child);
    return child;
  }

if you look at the getting started guide of bot_toast package, they've an example at step 3.

Update: Or utilize the builder methods provided by BotToast or EasyLoading such as:

builder: EasyLoading.init(builder: BotToastInit()),
