注意：包没有缩进

pubspec.yaml 第 18 行第 3 列的错误：包可能不会将自己列为依赖项。 flutter_google_places：^0.2.1
^^^^^^^^^^^^^^^^^^^^^

pubspec.yaml 文件：

name: flutter_google_places
description: A new Flutter application.

# 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.
# Read more about versioning at semver.org.
version: 1.0.0+1

environment:
  sdk: ">=2.0.0-dev.68.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  flutter_google_places: ^0.2.1
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter

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

# 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/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

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

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/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,

【解决方案1】：

您不能拥有与您的项目同名的依赖项

name: flutter_google_places

您需要更改name: ...

【讨论】：

【解决方案2】：

项目名称和依赖名称必须不同。

姓名：

 name: flutter_google_places

和

dependencies:
  flutter:
    sdk: flutter
  flutter_google_places: ^0.2.1

不要使用 project_name 和 dependency_name 相同的字符串
示例：- pubspec.yaml 文件

name: sqflite          //project_name
description: A new Flutter application.
publish_to: 'none'
version: 1.0.0+1
environment:
  sdk: ">=2.7.0 <3.0.0"
dependencies:
  flutter:
    sdk: flutter
sqflite: ^1.3.1+1       //dependency_name

【解决方案3】：

我遇到了一个非常相似的问题...因为我创建了名为“Flutter_modular”的项目，并尝试在我的 pubspec.yaml 中插入“flutter_modular”。

dependencies: 
  flutter:
    sdk: flutter
  flutter_modular:

项目名称不能与依赖项相同。

【讨论】：

感谢@Rafael 是的，项目名称不能与依赖项相同。

【解决方案4】：

您的项目名称一定有问题。项目名不能与包名相同。
