Example : A dismissed Slidable widget is still part of the tree.

[giorgio79]

Hello,

Fixed the example so it works with the latest Flutter :)

I am noticing that the Slideable widget when dismissed emits a small error. Please see video. Any tips how to make this issue go away? :

dismissed.widget.still.part.of.the.tree.error.webm

(https://github.com/wwwdata/implicitly_animated_reorderable_list/assets/283347/ee9b58ed-46bf-42a1-92cd-abfbcbb67af7)

The recommended solution by Stackoverflow is to use UniqueKey instead of ValueKey https://stackoverflow.com/questions/55792521/how-to-fix-a-dismissed-dismissible-widget-is-still-part-of-the-tree-error-in

When switch to that, I am getting a small flicker in animation, as both Dismissible and AnimatedList is doing some animation.

double.animation.webm

The following assertion was thrown building SlidableDismissal(state: _SlidableDismissalState#c7a52(ticker inactive)):
A dismissed Slidable widget is still part of the tree.


Make sure to implement the onDismissed handle of the ActionPane and to immediately remove the Slidable widget from the application once that handler has fired.

Stackoverflow to the rescue!!!!

need to use confirmDismiss instead of onDismiss...

Testing the proposal right now

Still not perfect, but this one hopefully flutter/flutter#29844

So what about the suggestion to set removeDuration to zero and work with this confirmDismiss callback?

[giorgio79]

Yes, tried that. For some reason I still see the flicker in the Implicitly Animated widget. I tested going back to simple AnimatedList and no flicker there. Probably gonna go with AnimatedList for now.
