Add a SlidableController about flutter_slidable

[pushpendraKh]

@tidharnitzan I got the problem.
You should not create new instance of slidableController.
You are doing this inside cell, hence ending up creating new instance of controller everytime.

Instead, create slidableController in the controller itself and pass it to the cell and use it.
It will work.

hi, it doesn't seem to work.
while I defined it correctly in the ctor I can still open several items and they all remain opened (I expected the other to auto close when another one is opened).

code:
...
final SlidableController slidableController = new SlidableController();
...
child: Slidable(
key: Key(_row.animalID),
controller: slidableController,
delegate: new SlidableBehindDelegate(),
actionExtentRatio: 0.25,
secondaryActions: [

....

Hi @hjJunior,
The activeState property is null until a Slidable has been slid. This is why you can't use it in the onTap callback of the ListTile.
For the Slidable.of, it's probably because the ListTile is created under the same context than the Slidable. You need to create the ListTile under a Builder widget to provide a new scope with a BuildContext that is "under" the Slidable.

Widget build(BuildContext context) => Slidable(
    delegate: new SlidableDrawerDelegate(),
    actionExtentRatio: 0.25,
    closeOnScroll: false,
    controller: slidableController,
    child: new Builder(builder:  buildChild),
    actions: <Widget>[
      new IconSlideAction(
        caption: 'Archive',
        color: Colors.blue,
        icon: Icons.archive,
        onTap: () => print('Archive'),
      ),
      new IconSlideAction(
        caption: 'Share',
        color: Colors.indigo,
        icon: Icons.share,
        onTap: () => print('Share'),
      ),
    ]
  );

But I didn't design the animation to be programmatically called, so you will probably have an unexpected behavior.

@BrianDevOK You are right. Currently, v1.1.0 does not solve this but the next version will definitely solve this automatically as the required change is already pushed in master branch here

You can test the same in example project by running main_demo.dart

This is maybe not the right solution, because we'll have to maintain a list of Slidables or Keys and this could lead to potential issues, or complexity.
To open/close a Slidable based on a parent widget state we could have a boolean value to indicate the initial state.
For a slide action, we could create an of method to get the state and add open/close methods on the state.

[rhwoodpecker]

If this slide action is open, when I click on this item or other item, the slide action will be closed. When we click, we can traverse the other slide actions according to the keys.

[letsar]

With the 0.3.0, I don't think we need a SlidableController now.

[hjJunior]

I'm trying to open when user clicks on child context, for more exacty when ListTile onTap event, so I stucked because I tried all of these two methods, and of these, before I got the call to function I got null

  slidableController.activeState?.open();
  Slidable.of(context)?.close();

[hjJunior]

I have tried but keeps returning null :(

    Widget build(BuildContext context) =>Slidable(
        delegate: new SlidableDrawerDelegate(),
        actionExtentRatio: 0.25,
        controller: slidableController,
        child: Builder(builder: (context) => _SlidableChild(widget.produtoPedido)),
        secondaryActions: <Widget>[
          ...
        ]
    );

And the child

class _SlidableChild extends StatelessWidget {
  final ProdutoPedido produtoPedido;
  _SlidableChild(this.produtoPedido);

  @override
  Widget build(BuildContext context) => ListTile(
    onTap: () {
      Slidable.of(context)?.open();
    },
    leading: (produtoPedido.pago) ? Icon(Icons.check_circle, color: Colors.green,) : null,
    title: Text('1x ${produtoPedido.produto.nome}'),
    subtitle: Text(produtoPedido.showDetalhes),
    trailing: Text(produtoPedido.valorFormatado),
  );
}

[letsar]

@hjJunior can you please, paste the minimal code to reproduce this? Because I tested it with a function or a another widget like you, want under a Builder, the Slidable.of(context) is not null 😕

[pushpendraKh]

@tidharnitzan Did it solve? I am also facing the same problem.

[tidharnitzan]

Not AFAIK. Still waiting for a response from developer for the code snippet above.

[pushpendraKh]

It's working in this code https://pub.dartlang.org/packages/flutter_slidable#-example-tab-
May be we are doing something wrong.

[tidharnitzan]

@pushpendraKh - You are right! I'm still new to Flutter and totally missed that. all working great. thanks. !

I need one Help I am using PopUpMenu in Slidable i want to close the slide when ever use clicks on PopupMenu item.
Slidable(
closeOnScroll: true,
key: Key(task.taskId),
controller: slidableController,
actionPane: SlidableScrollActionPane(),
actionExtentRatio: 0.2,
actions: [
//////////////// This is an PopUp///////////////////
PopupMenuButton(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10.0),
),
initialValue: selectedTaskStatus,
onSelected: (TaskStatus value) {
Slidable.of(context)?.close();
setState(() {
///////////////// I want to close the slide when onSelect Call///////////////////
selectedTaskStatus = value;
task.taskStatus = value.taskStatus;
_updateTask(context, task, viewModel);
});
},
child: IconSlideAction(
closeOnTap: false,
icon: Icons.playlist_add_check,
color: AppColors.swipe_geen,
caption: AppStrings.STATUS_LBL,
foregroundColor: AppColors.pureWhite,
),
itemBuilder: (BuildContext context) {
return getStatus.map((TaskStatus taskStatus) {
return PopupMenuItem(
value: taskStatus,
child: Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
],
),
],
));
}).toList();
},
),
],
);

Add this onTap() and call a separated widget in child property of Slidable and don't write child inside Slidable wid.

onTap: () {
Slidable.of(context).open();
},
//===================== Slidable Widget
Slidable(
controller: controller,
actionExtentRatio: 0.35,
actionPane: SlidableDrawerActionPane(),
actions: [
// Some Widget
],
secondaryActions: [
// Some Widget
],
child: Temps (),
);

//========= This is child in Slidable
class Temps extends StatefulWidget {
@OverRide
_TempsState createState() => _TempsState();
}

class _TempsState extends State {
@OverRide
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
print(Slidable.of(context));
Slidable.of(context).open();
},
child: Container(
color: Colors.white,
child: ListTile(
leading: CircleAvatar(
backgroundColor: Colors.amber,
child: Text("'{item.index}'"),
foregroundColor: Colors.white,
),
title: Text("item.title"),
subtitle: Text("item.subtitle"),
),
),
);
}

It worked for me <3

[BrianDevOK]

I'm having trouble getting the slidableController initialised. Looks to require a vsync param. I've done that with various animation controllers, but stuck here. Can someone give an example.

I need to get the slidable to close when I swipe a different slidable, and need it to close when I tap a different slidable. Once I can get the slidableController initialised, I think I can take it from there. Thanks

[pushpendraKh]

@BrianDevOK In latest version, SlidableController is not exposed and is meant to use internally.

So, you can wrap your ListView in SlidableAutoCloseBehavior which will close other Slidable.

[BrianDevOK]

Thanks... I had tried the SlidableAutoCloseBehavior but not around the ListView. That took care of closing when swiping another item.

How do I close it in this example: Swipe list item 1. Then tap on list item 2

In this example, my tap on list item 2 takes me to another view and when I hit back to my list, list item 1 is still open/slid.

Thanks
