  <p>I added plugin sliding up panel plugin for flutter. Here is the following code</p>
  <pre><code>collapsed:Container(
              decoration: BoxDecoration(
                  color: Colors.white,
                  borderRadius: radius
              ),
              child: Padding(
                  padding: EdgeInsets.only(left: 5,right: 5),
                  child:Container(
                    height: 90,
                    child: Column(
                        mainAxisAlignment: MainAxisAlignment.end,
                        children: &lt;Widget&gt;[
                          Container(//first container 
                            height: 20,
                            width: 60,
                            child: Padding(
                              padding: EdgeInsets.only(bottom: 5,top: 5),
                              child:RaisedButton(
                                  color: Colors.white,
                                  onPressed: (){},
                                  shape: RoundedRectangleBorder(borderRadius: new BorderRadius.circular(30.0))
                              ) ,
                            ),
                          ),
                          Container(//second container
                            height: 60,
                            child: ListTile(
                              onTap: (){},
                              title: Text('Cart: ',style: TextStyle(color: Colors.black),),
                              trailing: Text(&quot;Total( &quot;+&quot; :sum)&quot;),
                            ),
                          )
                        ]
                    ),
                  )
              )
          ),
