I am facing the problem

If two widgets added in a column, there is space between the widgets . I need to remove the space between them. how to acheive it.

```
    Container(height: 50,
                width: 50,
                color: Colors.grey,
                child: Column(mainAxisAlignment: MainAxisAlignment.center,
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: <Widget>[

                    Flexible(flex: 2,
                        child: Container(color: Colors.indigo,
                            child: SizedBox(child: Icon(
                              Icons.filter_list, color: Colors.white,),))),            
                    Flexible( flex:1, child:
                  Text('5',style: TextStyle(color: Colors.black),)
                ),]));
