dismiss on button tap about flutter_slidable HOT 5 CLOSED

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.

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.

there are no examples with SlideActionBuilderDelegates and Slidable.builder.

also in version 2 we dont have this builder method.

how to achive a working result with slidablecontroller dismiss method without A dismissed Slidable widget is still part of the tree.
