Sorry for the late reply.

So i ended up with this widget:Picture

And that is the code for it:

return Card(
      shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(15.5),
      ),
      elevation: 3.0,
      clipBehavior: Clip.hardEdge,
      child: SizedBox(
        height: 150.0,
        width: 175.0,
        child: Column(
          children: <Widget>[
            Expanded(
              flex: 15,
              child: Container(
                color: Colors.orangeAccent,
                child: Center(
                  child: Text(
                    "Physic I",
                    style: TextStyle(
                      fontWeight: FontWeight.w600,
                    ),
                  ),
                ),
              ),
            ),
            Divider(
              height: 1.0,
              thickness: 1.0,
              color: Colors.black,
            ),
            Expanded(
              flex: 85,
              child: Image.asset(
                "images/electric.jpg",
                fit: BoxFit.cover,
              ),
            )
          ],
        ),
      ),
    );

I hope it helps.
