            child: ListTile(
                leading: SizedBox(
                    height: 150.0,
                    width: 150.0, // fixed width and height
                    child: Image.asset("assets/images/test.png"))),
          ),
        ),
      ],
    ),
  ),
);

Try this:

    Scaffold(
      appBar: AppBar(
        title: Text("Card over stack"),
      ),
      body: Padding(
        padding: const EdgeInsets.all(20),
        child: Stack(
          children: <Widget>[
            Positioned(
              top: 20,
              left: 40,
              right: 0,
              child: Container(
                decoration: BoxDecoration(
                    borderRadius: BorderRadius.all(Radius.circular(20)),
                    color: Colors.lightBlueAccent,
                    boxShadow: [
                      BoxShadow(
                        color: Colors.grey.shade300,
                        blurRadius: 5,
                        spreadRadius: 2,
                        offset: const Offset(4, 4),
                      )
                    ]),
                height: 150,
                child: Padding(
              padding: const EdgeInsets.only(left: 75),
              child: Column(
                mainAxisAlignment: MainAxisAlignment.spaceAround,
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Text('abcdefghiklmn'),
                  Text('abcdefghiklmn'),
                  Text('abcdefghiklmn'),
                  Text('abcdefghiklmn'),//code any here
                ],
              ),
            ),
              ),
            ),
            Positioned(
              top: 0,
              child: Container(
                height: 150,
                width: 100,
                decoration: BoxDecoration(
                  boxShadow: [
                    BoxShadow(
                      color: Colors.grey.shade200,
                      blurRadius: 5,
                      spreadRadius: 2,
                      offset: const Offset(-3, -3),
                    )
                  ],
                  borderRadius: const BorderRadius.all(Radius.circular(20)),
                ),
                child: ClipRRect(
                  borderRadius: const BorderRadius.all(Radius.circular(20)),
                  child: Image.asset(
                    'assets/images/test.png',
                    fit: BoxFit.cover,
                  ),
                ),
              ),
            ),
          ],
        ),
      ),
    );

This is my result:
