android-studio - 在我的 Assets 上获取 "No file or variants found for asset"发现错误

Question

尝试运行我的应用程序时，出现此错误。有任何想法吗？
(以下)

Launching lib\main.dart on SM J200Y in debug mode...
Running Gradle task 'assembleDebug'...
√ Built build\app\outputs\apk\debug\app-debug.apk.
Error detected in pubspec.yaml:
No file or variants found for asset: assets/credentials.json.

我已经检查了yaml文件，并且格式似乎还不错。我茫然想要这个问题。 (也如下)

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:
  - assets/credentials.json

Answer 1

检查 Assets 的缩进。通常，从新行开始应有3个空格。

assets:
 - assets/credentials.json // <-- count three spaces from start
