Question

昨天我尝试放置一个图像，但效果很好，但是当我尝试再次运行它时，出现了这个错误：

Restarted application in ٢٬٧٦٥ms.

这是Yaml：

flutter:
  uses-material-design: true
  assets:
    - images/cat.jpg

和主要

child: Image(
  image: AssetImage('cat.jpg'),
),

那这里有什么问题？

Answer 1

尝试更改此代码：

child: Image(
   image: AssetImage('cat.jpg'),
),

进入这个：

// add the full reference of the image
child: Image(
   image: AssetImage('images/cat.jpg'),
),

如果这对您不起作用，请尝试将图像文件夹移动到lib文件夹中，并更改引用，如下所示：

内部yaml：

flutter:
   uses-material-design: true
   assets:
      - lib/images/cat.jpg

在您的飞镖代码中：

//the full reference of the image
child: Image(
   image: AssetImage('lib/images/cat.jpg'),
),

Answer 2

您必须像在 pubspec.yaml

中声明的那样，为图像小部件提供完整路径

child: Image(
  image: AssetImage('images/cat.jpg'),
),

将图片文件添加到这样的应用顶级目录中

->(Your_App_Name)
  ->images
   ->cat.jpg

Answer 3

在主文件中添加完整路径。

Image(
   image: AssetImage('images/cat.jpg'),
),
