NoSuchMethodError after update to 0.5.0 about flutter_slidable

[jaumard]

I can confirm the problem (and the solution ^^) would be nice to have this patch and deploy @letsar :)

PR created.

Fixed in 0.5.2

Until we have this PR merged, I am using a workaround, set dismissal to the following:

dismissal: SlidableDismissal(
     child: SlidableDrawerDismissal(),
     onWillDismiss: (actionType) {
         return false;
     },
),

this is enforcing to have a dismissal property by always is canceling the dismissal actions

[PabloPL]

In slidable.dart (in flutter_slidable lib) replace

double get _dismissThreshold =>
    widget.dismissal?.dismissThresholds[actionType] ?? _kDismissThreshold;

With something like this

double get _dismissThreshold {
    if (widget.dismissal == null) return _kDismissThreshold;
    else return widget.dismissal.dismissThresholds[actionType] ?? _kDismissThreshold;
  }

For me it's working fine

Thanks, @eponcedeleon. Your solution worked here, but I had to add a key property to theSlidable object in order for it to work

[tegab]

can you show code on how you solved it.. thnx

[jeffaknine]

First time trying the package and I'm running into this issue as well. @PabloPL maybe you could send a PR to get this fixed ?
