flutter异常记录

1 格式错误

 uses-material-design: true

  # To add assets to your application, add an assets section, like this:
    assets:
       - img/

  #  - 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.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

运行后会产生如下错误
Error on line 44, column 4 of pubspec.yaml: Expected a key while parsing a block mapping.
assets:
^
原因是 assets相对flutter: 前面多了一个空格

修改后 如下正常

  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
       - img/
