Flutter – Stack of Card using Stack Widget

Based on the name I think you can get the idea of what kind of widget is it. Stackwidget will provide a way of overlapping several children in a simple way.

Based on the flutter document stack widget is

A widget that positions its children relative to the edges of its box


Key points

  • Each child can be positioned or non positioned.
  • Position element need to wrap with Positioned Widget and need to have one non-null property
  • Default non positioned children positioned in top left corner.
  • We can change the alignment using alignment attribute and child views will be act according that.
  • Stack paints its children in order with the first child being at the bottom.


In this tutorial I’m gone a show to how to create tinder like card view using stack widget.

First we create a Stack widget and we need to assign Alignment.center to the alignment attribute.

alignment: Alignment.center,
children: <Widget>[],

We can add arrays of child widget for stack. next I am gone a add a 3 card widget as a children widgets. The thing is we need to wrap this card with the Positioned widget. Otherwise all the widget will overlap and we cannot differentiate each card.

top: 20,
child: Card(
elevation: 8,
color: Color.fromARGB(255, 0, 255, 0),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10)),
child: Container(
width: 220,
height: 300,

In Positioned widget we can define the distance from the top. For each Card I will increase the distance by 10. Then we can see the nice stack of cards. Check the video If you need more clarification.
