## Features

async_value_group is a a Dart library for grouping some [riverpod](https://github.com/rrousselGit/riverpod) `AsyncValue`s into single `AsyncValue`.

- Grouping some `AsyncValue`s into single `AsyncValue` and retrieve all `AsyncValue.data` as a tuple.

- Waiting to be done multiple asynchronous process.

- If you use hooks_riverpod, call `AsyncValue.when` only once in `Widget.build` method even if multiple AsyncValues are required.

## Usage

```dart

import 'package:flutter/material.dart';

import 'package:hooks_riverpod/hooks_riverpod.dart';

import 'package:async_value_group/async_value_group.dart';

class TweetsPage extends HookConsumerWidget {

  const TweetsPage({Key? key}) : super(key: key);

  @override

  Widget build(BuildContext context, WidgetRef ref) {

    return AsyncValueGroup.group2(

      ref.watch(tweetsProvider),

      ref.watch(userProvider),

    ).when(

      data: (t) => t.$1.isEmpty ? const TweetsEmpty() : TweetsBody(tweets: t.$1, user: t.$2),

      error: (error, st) => ErrorPage(error: error),

      loading: () => const Loading(),

    );

  }

}

```
