Set SlidableController.activeState.open() with onTap

[DARdk]

Thank you for an awesome Flutter implementation!
Is it possible to open the drawer and show all the iconslider actions through a onTap event on the Slidable? See the scenario on the two images below:

Currently the only example that is given is to close the drawer as seen in Issue 33:
#33
However, if the Slidable is not in an activestate, the output of:
slidableController.activeState is null, and hence I am not able to do:
slidableController.activeState.open() because it will simply say:
"The method 'open' was called on null"

See the example code below:

I see. This widget wasn't created with this kind of feature in mind. I need to rewrote some parts in order to be animated by sliding or with a call to a function.
For the moment, you can call Slidable.of(context) inside the child of a Slidable to get its state and call open(). But you won't get any animation and you won't be able to tell whether you want to open the primary or secondary actions.
I won't be able to do it now, but give me some time and I will do it 🙂.

Thank you for the prompt answer letsar.
I did not have any luck with your suggestion (my child of Slidable is a ListTile). The Slidable.of(context) was null in all cases.
However, I will just implement a in-app guidance, and keep this functionality as a future feature. Thank you for considering this enhancement in a future version.

If Slidable.of(context) was null, it's maybe because the context is a parent of the Slidable. It can be related to

Thank you, I will keep you posted on my advancement 🙂 .

I've implemented a solution for this on my fork, so if you could have a look...
Note that I've also made some other changes.
Perhaps I've broken something😁.

[DARdk]

Amazing! Thanks both. I added your version to my pubspec.yaml, and change from Slidable to Slidable.builder. Then wrapped the child of Slidable.builder inside a builder like:
child: new Builder(builder: (contextNew) => new Column(....)
And it perfectly animates the slide-effect for my secondaryactions during onTap.
However, somehow I need to slide it the first time to make it "recognize" the object, THEN a onTap will slide it out. But If I entered the page and directly press it: Nothing happens... Any clue?
Thanks a lot.

[letsar]

Great. I've been working on a complete refactor of the API (you can see the work in progress in the https://github.com/letsar/flutter_slidable/tree/feature/refactor branch) and I added the feature to animate on when opening. I will keep you posted on the advancement.

@DARdk are you calling open() without the actionType?

[DARdk]

@miDeb Yes, I did not add the actionType. By adding it as: Slidable.of(context).open(actionType: SlideActionType.secondary);
It works every time! Thanks, this is perfect

@DARdk thanks so much, you save me!

How to check if the Slidable Item is opened or closed?

[letsar]

Closing as this is resolved

[armandojimenez]

How can I check if the slideable is already open to close it?

[saigopin]

@armandojimenez any solution?

[armandojimenez]

I use this:

if (Slidable.of(context)!.renderingMode == SlidableRenderingMode.none) {
              Slidable.of(context)!.open(actionType: SlideActionType.secondary);
} else {
              Slidable.of(context)!.close();
}

When I tap the cell, it opens or close depending if it's already open. Do only weird issue, is that if I open it via a tap, and them try to close it by sliding, it does without animation, and looks weird. But if you closed it back by tap it works fine.

@armandojimenez what should instead of rendering mode in latest null satety version 1.0.0. I want to open the slider at a time on tapping the list item , when i tap on second item , first item just closes its slide but second item not opening it slide
