You don't need Stack to get that view - it can be done using Column & Material widget.

return Scaffold(
        body: new Container(
      decoration: new BoxDecoration(color: Colors.blue),
      child: new Center(
          child: MergeSemantics(
            child: Padding(
              padding: const EdgeInsets.all(16.0),
              child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        crossAxisAlignment: CrossAxisAlignment.stretch,
        children: <Widget>[
              Card(
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.stretch,
                  children: <Widget>[
                    Material(
                      elevation: 24.0,

                      ),

If you want to resize or alter the card view Then just put Card inside the Container view then adjust your container size. This link will help you :https://stackoverflow.com/a/50017126/7418129

Just Put Card in Container

Padding(
            padding: EdgeInsets.all(20),
            child: Container(
              height: 50,
              width: double.infinity,
              child: Card(
                child: Align(
                    alignment: Alignment.centerLeft,
                    child: Text("Edit Profile")),
              ),
            ),
          )

In my case, using the DevTools I found out that the Card has a margin of 1 by default, u can use the Card inside the Container, but if u want the Card to completely fill the Container set the Card's margin to: margin: EdgeInsets.zero. – Ramiro G.M. May 04 '22 at 21:05
It's better to use a SizedBox instead of a container. – Praveen Thirumurugan May 07 '22 at 07:35
