运行 flutter 时，我不断收到 pubsepc.yaml 错误

Question

这是我的 pubsepc.yaml 代码

version: 1.0.0+1

environment:
sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  rxdart: ^0.27.1
  path_provider: ^2.0.2
  image_picker: ^0.8.0+3
  pendatic: ^1.8.0

  cupertino_icons: ^1.0.2

  dev_dependencies:
    flutter_test:
      sdk: flutter

  flutter:
     uses-material-design: true

     To add assets to your application, add an assets section, like this:
     assets:
       - assets/images/apple-in-hand.jpg
       - assets/images/apricots.jpg
       - assets/images/asparagus.jpg

我不断收到的错误消息如下

PS C:\Users\Geon-Young.Hong\e_commerce> flutter packages get
Error detected in pubspec.yaml:
Unexpected child "To add assets to your application, add an assets section, like this" found under "flutter".
Please correct the pubspec.yaml file at C:\Users\Geon-Young.Hong\e_commerce\pubspec.yaml

运行 flutter doctor 时没有发现问题

PS C:\Users\Geon-Young.Hong\e_commerce> flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, 2.0.4, on Microsoft Windows [Version 10.0.19042.1052], locale en-US)

[√] Chrome - develop for the web
[√] Android Studio (version 4.1.0)
[√] VS Code (version 1.57.0)
[√] Connected device (2 available)

这是 flutter & dart 版本信息

Flutter 2.0.4 • channel stable • https://github.com/flutter/flutter.git
Framework • revision b1395592de (2 months ago) • 2021-04-01 14:25:01 -0700
Engine • revision 2dce47073a
Tools • Dart 2.12.2

我无法导入 rxdart、image_picker 包。 （在lib之外有一个assets目录） 这可能是与版本相关的问题或其他问题。

有人可以帮我解决这个问题吗？

非常感谢！

Answer 1

从 To add assets to your application, add an assets section, like this: 中删除 pubspec.yaml 部分

Answer 2

该错误告诉您有一个意外的孩子，"To add assets to your application, add an assets section, like this:" 该行不应该在那里，将其注释掉或删除它，pub get 应该可以正常运行

Answer 3

将此代码替换为您的pubsepc.yaml我所有的代码如下。

version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  rxdart: ^0.27.1
  path_provider: ^2.0.2
  image_picker: ^0.8.0+3
  pendatic: ^1.8.0

  cupertino_icons: ^1.0.2

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:
  uses-material-design: true
    
  # To add assets to your application, add an assets section, like this:
