dismiss on button tap

[CedSW]

Hi is it possible to dismiss row on button tap?
I would like to display confirmation dialog first and if user hit ok, dismiss the row.
Thank you!

Hi,
I thought we could do this with Scrollable.of but we cannot use this after a dialog show.
I will try to implement some kind of controller, and see if we can use this.

Oh I succeeded to do what you want by getting the state before showing the AlertDialog.
The code below is what I put in the tap callback of my slide action:

onTap: () async {
                  var state = Slidable
                      .of(context);
                  var dismiss = await showDialog<bool>(
                    context: context,
                    builder: (context) {
                      return new AlertDialog(
                        title: new Text('Delete'),
                        content: new Text('Item will be deleted'),
                        actions: <Widget>[
                          new FlatButton(
                            child: new Text('Cancel'),
                            onPressed: () => Navigator.of(context).pop(false),
                          ),
                          new FlatButton(
                            child: new Text('Ok'),
                            onPressed: () => Navigator.of(context).pop(true),
                          ),
                        ],
                      );
                    },
                  );

                  if (dismiss) {
                    state.dismiss();
                  }
                },

thank you for you reply, but unfortunately I didn't manage to reproduce your solution.
Error is: NoSuchMethodError: The method 'dismiss' was called on null. I manage to come up with workaround using streams, but I still wonder where is the problem :/

here is my code

    SlideAction(
      onTap: () async {
        var state = Slidable
            .of(context);
        var dismiss = await showDialog<bool>(
          context: context,
          builder: (context) {
            return AlertDialog(
              title: Text(S.of(context).confirmDeletion),
              content: Text(S.of(context).deletionDescription),
              actions: <Widget>[
                FlatButton(
                  child: Text(S.of(context).cancel),
                  onPressed: () => Navigator.of(context).pop(false),
                ),
                FlatButton(
                  child: Text(S.of(context).ok),
                  onPressed: () =>  Navigator.of(context).pop(true),
                )
              ],
            );
          },
        );

        if (dismiss) {
          state.dismiss();
        }
      },
      color: _tag.color,
      child: Icon(Icons.delete, color: Colors.white,),
    )
  ],

I forgot to mention you should use the Slidable.builder constructor and SlideActionBuilderDelegates, otherwise you will end up with the same context as the Slidable. This is why Slidable.of(context) is null.
