【解决方案1】：

您需要使用 FileImage 而不是 AssetImage

            decoration: new BoxDecoration(
                color: Colors.transparent,
                image: new DecorationImage(
                  image: new FileImage(File(image.path)),
                  fit: BoxFit.cover,
                ),
        
              ),

 You can also do one thing check the _image value if it null shows image through your assets if not then you call it through FileImage(_image!)

//////code   
File ?_image;
       
     _image==null?Stack(
