项目在Flitter项目中上载图像时挂起

Question

我要加载图像的文件

class _HomeState extends State<Home> {
      @override
      Widget build(BuildContext context) {
        return Container(
          height: 250,
          child: Card(
            child: Image.asset(
              '../../assets/images/person.jpg',
              fit: BoxFit.cover,
            ),
            shape: RoundedRectangleBorder(
              borderRadius: BorderRadius.circular(10.0),
            ),
            elevation: 5,
            margin: EdgeInsets.all(10),
          ),
        );
      }
    }

pubspec.yaml

 # To add assets to your application, add an assets section, like this:
 assets:
  - assets/images/person.jpg
  - assets/images/burger.jpg
