you can use MultiProvider to do so. as following.

MultiProvider(
  providers: [
    ChangeNotifierProvider(builder: (_) => FirstProvider()),
    ChangeNotifierProvider(builder: (_) => SecondProvider()),
  ],
  child: someWidget,
)

Hey builder was deprecated you can refer this link for more info Builder Deprecation

We can use Multiple providers like this

 MultiProvider(
          providers: [
            ChangeNotifierProvider<ProductDataProvider>(
                create: (_) => ProductDataProvider()),
            ChangeNotifierProvider<AuthenticationProvider>(
                create: (_) => AuthenticationProvider()),
          ],
          child: Container())

You can use it like this:

    MultiProvider(
      providers: [
        ChangeNotifierProvider(create: (context) => CartModel()),
        Provider(create: (context) => SomeOtherClass()),
      ],
      child: MyApp(),
    ),

Smart answer for considering, that Providers could be used without ChangNotifiers too! +1. thanks! – user3833732 Jul 22 '22 at 13:20
