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`:

  ```dart
  @riverpod
  Future<String> breweryName(Ref ref) async {
    final response = await http.get(
      Uri.https('api.openbrewerydb.org', '/v1/breweries/random'),
    );
    final json = jsonDecode(response.body) as List;
    return (json.first as Map)['name']! as String;
  }
  ```

- Listen to the network request in your UI and gracefully handle loading/error states.

  ```dart
  class Home extends ConsumerWidget {
    @override
    Widget build(BuildContext context, WidgetRef ref) {
      final breweryName = ref.watch(breweryNameProvider);
      // Perform a switch-case on the result to handle loading/error states
      return switch (breweryName) {
        AsyncData(:final value) => Text('data: $value'),
        AsyncError(:final error) => Text('error: $error'),
        _ => const Text('loading'),
      };
    }
  }
  ```
