Flutter 10 — 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
- 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.
Stack( 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.
color: Color.fromARGB(255, 0, 255, 0),
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.
