android pp\src\main es\mipmap-xxxhdpi\ic_launcher.png：AAPT：错误：无法读取 PNG 签名：文件不以 PNG 签名开头

Question

正在使用包 flutter_launcher_icons 为我的 flutter 应用程序生成启动器图标，

使用文档中提到的方法，我添加了该文件并在我的

pubspec.yaml

上提到了它

flutter_icons:
  android: launcher_icon
  image_path: assets/images/launcher_icon.png
  ios: true
  remove_alpha_ios: true

然后使用

调用它

flutter pub get
flutter pub run flutter_launcher_icons

所有文件的生成都没有问题，但是当我运行时

flutter build appbundle --release

收到此错误：

FAILURE: Build failed with an exception.

这是我第二次收到此错误。我只是生成新的启动器图标并将其替换为导致错误的旧图标。使用 https://www.appicon.co/.
