riverpodのパッケージをまとめてインストールする

\亡くなってるんですけど😇

riverpod公式のページで、必要なパッケージをまとめてインストールできる便利なコマンドが消えてた😱
お亡くなりになられたか。。。

⭐️なので再現しました!

これを。。。

flutter pub add flutter_riverpod
flutter pub add riverpod_annotation
flutter pub add dev:riverpod_generator
flutter pub add dev:build_runner
flutter pub add dev:custom_lint
flutter pub add dev:riverpod_lint

💡バックスラッシュで改行して追加するに変更します!

flutter pub add \
flutter_riverpod \
riverpod_annotation \
dev:riverpod_generator \
dev:build_runner \
dev:custom_lint \
dev:riverpod_lint

hooks_riverpodの場合はこちら

flutter pub add \
hooks_riverpod \
riverpod_annotation \
dev:riverpod_generator \
dev:build_runner \
dev:custom_lint \
dev:riverpod_lint

flutter_hooksも追加してください!

flutter pub add flutter_hooks

yamlファイルにパッケージが追加されていればOK!

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.

  sdk: '>=3.1.0 <4.0.0'

# Dependencies specify other packages that your package needs in order to work.
# To automatically upgrade your package dependencies to the latest versions
# consider running `flutter pub upgrade --major-versions`. Alternatively,
# dependencies can be manually updated by changing the version numbers below to
# the latest version available on pub.dev. To see which dependencies have newer
# versions available, run `flutter pub outdated`.
dependencies:
  flutter:
    sdk: flutter


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^1.0.2
  flutter_riverpod: ^2.4.5
  riverpod_annotation: ^2.3.0

dev_dependencies:
  flutter_test:
    sdk: flutter

  # The "flutter_lints" package below contains a set of recommended lints to
  # encourage good coding practices. The lint set provided by the package is
  # activated in the `analysis_options.yaml` file located at the root of your
  # package. See that file for information about deactivating specific lint
  # rules and activating additional ones.
  flutter_lints: ^2.0.0

# For information on the generic Dart part of this file, see the
# following page: https://dart.dev/tools/pub/pubspec

# The following section is specific to Flutter packages.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #   - images/a_dot_burr.jpeg
  #   - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700

  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

🔨プロバイダーを作ってみる

コマンドを打ってファイルが自動生成されたら成功!

import 'package:riverpod_annotation/riverpod_annotation.dart';
part 'hello.g.dart';

// flutter pub run build_runner watch --delete-conflicting-outputs
@riverpod
String hello(HelloRef ref) {
  return 'Hello World!';
}

コマンドを実行する

flutter pub run build_runner watch --delete-conflicting-outputs

hello.g.dartが生成された!

// GENERATED CODE - DO NOT MODIFY BY HAND

part of 'hello.dart';

// **************************************************************************
// RiverpodGenerator
// **************************************************************************

String _$helloHash() => r'983573bd1d45c7a75a21c09998e23fbbaa8a6ed9';

/// See also [hello].
@ProviderFor(hello)
final helloProvider = AutoDisposeProvider<String>.internal(
  hello,
  name: r'helloProvider',
  debugGetCreateSourceHash:
      const bool.fromEnvironment('dart.vm.product') ? null : _$helloHash,
  dependencies: null,
  allTransitiveDependencies: null,
);

typedef HelloRef = AutoDisposeProviderRef<String>;

最後に

なんであんな便利なコマンドを公式が消したのかは謎ですね。すごく便利だったのに。。。
誰かのお役に立てるかなと思って記事を書いてみました🧑‍🎓
