我无法添加容器

Question

嗨，我是 Flutter 新手。完成第一个容器后，我无法再添加另一个容器。它一直说错误。这是我的代码供您查看。

class UserProfile 扩展了 StatelessWidget { const UserProfile({ Key? key }) : super(key: key);

@覆盖小部件构建（BuildContext 上下文）{ return材质应用( debugShowCheckedModeBanner: false, 家：脚手架（应用栏：应用栏（

    backgroundColor: Colors.black,
      title: Row( 
      mainAxisAlignment: MainAxisAlignment.center, 
      
      children: [
      Text (' SmartParking '),
        Icon(Icons.directions_car,
         color: Colors.yellow, size: 30),
      ],), ),
  
  
  body: Container(
    child: Padding( 
        padding: EdgeInsets.all(20),
        child: Row( 
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: <Widget> [ 
                  Column(  
                    children: [ 
                      Icon(Icons.local_parking),
                  Text("Wallet"),
                  Text("RM40.00",
                      style: TextStyle( 
                        fontWeight: FontWeight.bold)
                        ,
                        ),
                     ],
                  ),
                   Column(

                    GestureDetector( 
                        onTap: () { 
                          Navigator.push(context, MaterialPageRoute(builder: (context) => LocationPage() 
                          ), );
                        },
                      ), 
                    Text ('points',
                    
                    ),
                    ],
                  ),
            ],
              ),
              ),

        
              ),
              
  
                ),

Wrap Container 在 Scaffold()

Scaffold(
child: Container(
    child: Padding( 
        padding: EdgeInsets.all(20),
        child: Row( 
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: <Widget> [ 
                  Column(  
                    children: [ 
                      Icon(Icons.local_parking),
                      Text("Wallet"),
                  Text("RM40.00",
                      style: TextStyle( 
                        fontWeight: FontWeight.bold),),
                     ],
                  ),
                   Column(  
                    children: [ 
                      Icon(Icons.account_balance_wallet_outlined),
                      Text("110", 
                  style: TextStyle( 
                    fontWeight: FontWeight.bold)), 
                    Text ('points',
                    ),
                    ],
                  ),
            ],
              ),
              ));
