How to use multiple Consumers for a single widget in flutter Provider

There are some other Consumer widgets. Consumer2, Consumer3, Consumer4 till Consumer6. If you want to listen 4 ChangeNotifier you can use Consumer4

Consumer4(
  builder: (context, changeNotifier1, changeNotifier2, changeNotifier3, changeNotifier4, child) {
    // your widget
  }
)

Yes you can add up to 6 consumers and will be as following

    Consumer2<AuthProvider, StorageProvider>(
    builder: (context, authProvider, storageProvider, child) {

    }
    )

There is another way to get access to your providers: Provider.of<SomeProvider>(context):

Widget build(BuildContext context) {
  final authProvider = Provider.of<AuthProvider>(context);
  final apiProvider = Provider.of<ApiProvider>(context);
  final storageProvider = Provider.of<StorageProvider>(context);

  // Do your usual stuff without wrapping it into Consumer,
  // just pass providers directly to your targets.
  return MyAwesomeWidget(
    authProvider,
    apiProvider,
    storageProvider,
  );
}
