Riverpod


A reactive caching and data-binding framework. https://riverpod.dev
Riverpod makes working with asynchronous code a breeze by:

  • handling errors/loading states by default. No need to manually catch errors
  • natively supporting advanced scenarios, such as pull-to-refresh
  • separating the logic from your UI
  • ensuring your code is testable, scalable and reusable

Welcome to Riverpod (anagram of Provider)!

For learning how to use Riverpod, see its documentation:
>>> https://riverpod.dev <<<

Long story short:

  • Define network requests by writing a function annotated with @riverpod:

    @riverpod
    Future<String> boredSuggestion(BoredSuggestionRef ref) async {
      final response = await http.get(
        Uri.https('https://boredapi.com/api/activity'),
      );
      final json = jsonDecode(response.body);
      return json['activity']! as String;
    }
    
  • Listen to the network request in your UI and gracefully handle loading/error states.

    class Home extends ConsumerWidget {
      @override
      Widget build(BuildContext context, WidgetRef ref) {
        final boredSuggestion = ref.watch(boredSuggestionProvider);
        // Perform a switch-case on the result to handle loading/error states
        return boredSuggestion.when(
          loading: () => Text('loading'),
          error: (error, stackTrace) => Text('error: $error'),
          data: (data) => Text(data),
        );
      }
    }
