Flutter，如何将UI放在按钮上？

Question

  Padding(
                      padding: const EdgeInsets.symmetric(horizontal: 80.0),
                      child: RaisedButton(
                        onPressed:() {
                          Navigator.push(context, MaterialPageRoute(builder: (context) => SecondPage()),
                          );
                        },
                      child: Container(
                        margin: EdgeInsets.symmetric(vertical: 0),
                        decoration: BoxDecoration(
                          borderRadius: BorderRadius.circular(50),
                          color: Color.fromRGBO(49, 39, 79, 1),
                        ),
                        child: Center(
                          child: Text(
                            "Login", style: TextStyle(color: Colors.white),),
                        )
                    )
                      ))]),

您可以从代码中看到，UI登录容器位于按钮的前面，但是尺寸非常小。无论如何，我可以将所有这些捆绑在一起吗？
