英文:

Flutter error on custom font : 'Error on line 78, column 4: Expected a key while parsing a block mapping.' in pubspec.yaml

问题

抱歉，我无法识别HTML实体并将其转换为文本。以下是您提供的文本的中文翻译：

"我是Flutter的新手，在尝试使用自定义字体时遇到了一个新错误。我查看了官方文档，甚至尝试复制那里的代码结构，但仍然不起作用。
这是错误消息：“在第78行，第4列上发生错误：在解析块映射时需要一个键。”
这是错误的截图：[自定义字体错误]

我尝试在pubspec.yaml中对行进行了缩进，但仍然不起作用。

这是我的pubspec.yaml文件：

# “family”键与字体系列名称以及包含字体资源和其他描述的“fonts”键。例如：
  fonts:
    - family: OpenSans
      fonts:
        - asset: fonts/OpenSans-Regular.ttf
        - asset: fonts/OpenSans-Bold.ttf
          weight: 700
    - family: Quicksand
      fonts:
        - asset: fonts/Quicksand-Regular.ttf
        - asset: fonts/Quicksand-Bold.ttf
          weight: 700
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700

我找到了问题。问题出在我的字体文件夹地址上。
我在pubspec.yaml文件中写错了字体的地址。
