在 Android Studio 中运行颤振应用程序显示奇怪的错误CacheNetworkImageProvider，即使我没有使用它。编译消息是：

  BoxDecoration(
    borderRadius:
    new BorderRadius.circular(4.0),
    image: DecorationImage(
        image: NetworkImage(
            featuredcontent[index].images),
        fit: BoxFit.cover),
  ),

编译器消息：

/C:/flutter/.pub-cache/hosted/pub.dartlang.org/cached_network_image-1.1.3/lib/src/cached_network_image_provider.dart:42:24: Error: The method 'CachedNetworkImageProvider.load' has fewer positional arguments than those of overridden method 'ImageProvider.load'.
