如何使用Flutter (Card Widget)进行此布局？

Card(
  child: ListTile(
    leading: Icon(Icons.person),
    title: Text('John Doe'),
    subtitle: Text('johndoe@example.com'),
  ),
),

Card(
  color: Colors.blue,
  elevation: 4.0,
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(10.0),
  ),
  child: ListTile(
    leading: Icon(Icons.person, color: Colors.white),
    title: Text('John Doe', style: TextStyle(color: Colors.white)),
    subtitle: Text('johndoe@example.com', style: TextStyle(color: Colors.white)),
  ),
),

Column(
  children: [
    Card(
      child: ListTile(
        leading: Icon(Icons.person),
        title: Text('John Doe'),
        subtitle: Text('johndoe@example.com'),
      ),
    ),
    Card(
      child: ListTile(
        leading: Icon(Icons.person),
        title: Text('Jane Smith'),
        subtitle: Text('janesmith@example.com'),
      ),
    ),
  ],
),
