Try something like this:

      RaisedButton(
        child: Text("Open"),
        onPressed: () => showDialog(
          context: context,
          builder: (context) {
            return Center(
              child: Container(
                margin: EdgeInsets.all(16),
                child: ClipRRect(
                    borderRadius:
                        BorderRadius.all(Radius.circular(10)),
                    child: Stack(
                      children: <Widget>[
                        Image.network("https://images.absolutdrinks.com/drink-images/Raw/Absolut/2f2f4c7b-9a52-467e-8c8f-6ad1f127bc35.jpg?imwidth=500",
                          fit: BoxFit.cover,),
                        Positioned(
                          right: 0,
                          bottom: 0,
                          child: FlatButton(
                            child: Text("Open"),
                            onPressed: () {},
                          ),
                        )
                      ],
                    ),
                  ),
                )
            );
          }
        ),
      )
