... user is in offline situation, to show local image , but I get this error

The placeholder property is for while the image is loading, so after the image is fully loaded, you will still get an error in offline mode since it still tries to load a NetworkImage which won't work in offline mode.

to solve the problem, you can use an Image.network, which has an errorBuilder - and will get called if the network image isn't found, and then, you should load an Asset image.

FadeInImage(
              height: 250,
              width: 300,
              placeholder: NetworkImage('https://picsum.photos/200/300.jpg'),
              image: Image.network(
                'https://fastly.picsum.photos/id/493/200/300.jpg?hmac=grrcfhF-iSyQuaMEkd8b4OH6Gn2W3xm7dUL4-955Vxw',
                errorBuilder: (BuildContext context, Object exception,
                    StackTrace? stackTrace) {
                  return Image.asset('/path/to/image.png');
                },
              ).image)
