Answer 1

You want to wrap your card in a Column because the inner Column take full height

 Column(children: [
      Card(
        margin: const EdgeInsets.all(10.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            AspectRatio(
              aspectRatio: 18.0 / 13.0,
              child: Image.network(
               "https://picsum.photos/200",
                fit: BoxFit.fill,
              ),
            ),
            Padding(
              padding: EdgeInsets.fromLTRB(16.0, 12.0, 16.0, 8.0),
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Text(
                    "Just add your desired image size (width & height) after our URL, and you'll get a random image.",
                    textAlign: TextAlign.center,
                  ),
                ],
              ),
            ),
          ],
        ),
      )
])
