“使用材料设计：真实”不适用于 pubspec.yaml 中的其他资产

如何解决“使用材料设计：真实”不适用于 pubspec.yaml 中的其他资产

在删除/评论此行之前，我无法向我的项目应用程序添加任何资源，例如图像、字体等

uses-material-design: true

错误

Error detected in pubspec.yaml:
Restarted application in ٨ms.
Error on line 25,column 4: Expected a key while parsing a block mapping.
   ╷
25 │    assets:
   │    ^
   ╵
Exception: Please correct the pubspec.yaml file at .\pubspec.yaml

除了这个问题，在pubspec.yaml中一切正常

name: mi_card
description: A new Flutter application.

version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  Flutter:
    sdk: Flutter

  cupertino_icons: ^0.1.2

dev_dependencies:
  Flutter_test:
    sdk: 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/

   fonts:
     - family: Pacifico
       fonts:
         - asset: fonts/Pacifico-Regular.ttf

     - family: Source Sans Pro
       fonts:
        - asset: fonts/SourceSanspro-Regular.ttf

但是因为我需要用到材质图标，所以需要和我的assets一起添加，那么如何解决这个问题？

解决方法

pubspec.yaml 对缩进敏感。

并且您在 uses-material-design: true 之后的 in 文件缩进一个空格，尝试将其删除，它会起作用。

复制并尝试：
