How to find the order of a Stack during testing in Flutter?
Say I have a Stack of widgets that are not the same:
return Stack(
children: <Widget>[
Container(),
Text('Hey'),
Positioned(top: 300.0, child: CustomWidget()),
],
);
How do I test the order of the child widgets? I could assign keys to each item, but how can I tell which item appears in front of another?
I could assign a key to my Stack, wrap each child in a Positioned, and then use find.byKey(stackKey) to get my Stack, and then use find.byType(Positioned) to get its children. This returns an Iterable which I can convert to a List. But, is find.byType() guaranteed to return the same order each time?

z-index is just a web/css term, indicating its height on the z plane. its not applicable to flutter (that i know of).

Right, in Flutter the property iselevation. The question is, how do we know the order of relative elevations, when we retrieve a list of Widgets in a Stack, during testing?

Right, in Flutter the property is
elevation. The question is, how do we know the order of relative elevations, when we retrieve a list of Widgets in a Stack, during testing?– Mary
