Riverpod 的 ConsumerWidget 在我的 flutter 项目中无法识别

Question

我已经在我的 flutter 项目中安装了 Riverpod，并且正在尝试创建一个扩展 ConsumerWidget 的类，但后者无法被我的 IDE（Android Studio）识别，并且它以红色下划线，尽管一切似乎都是正确的。

这是我的课：

import 'package:flutter/material.dart';
import 'package:testproject/models/message_model.dart';
import 'package:riverpod/riverpod.dart';

class MessageList extends ConsumerWidget {
  @override
  Widget build(BuildContext context, WidgetRef ref) {
    List<Message> messages = ref.watch(todosProvider);
    return widget();
  }
}

这是我的 pubspec 文件：

name: testproject
description: A new Flutter project.

# The following line prevents the package from being accidentally published to
# pub.dev using `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 used as CFBundleVersion.

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
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/notification_icon.png
  #   - images/a_dot_ham.jpeg
  fonts:
    - family: Pacifico
      fonts:
        - asset: fonts/Pacifico-Regular.ttf
    - family: Source Sans Pro
      fonts:
        - asset: fonts/SourceSansPro-Regular.ttf

不确定我是否错过了什么或者我是否做错了什么，但我无法找到它是什么。

“riverpod”包用于 dart 程序，因此删除了所有与 Flutter 相关的类。

尝试使用flutter_riverpod代替，我认为应该可行。
